Abstract:
We use the International Centre for Theoretical Physics (ICTP) Regional Climate Model (RegCM3) to study the impact of different domain sizes on the simulation of the West African summer monsoon rainfall and circulation features. RegCM3 simulates drier conditions over the default domain (RegCM-D1) and its westward extension (RegCM-D2), much less dryness over the eastward extended domain (RegCM-D3) and excessive wetness in the domain extended northward into the extratropical regions (RegCM-D4). This overestimation is related to the existence of larger source of humidity due to the inclusion of a more significant portion of the Atlantic Ocean and to a weakening of the African Easterly Jet (AEJ), which both favor stronger westerlies advecting moisture towards the land. The best performance is, however, captured in the RegCM-D3 experiment, and this originates from a simulation of moderate westerly moisture fluxes along with a stronger AEJ and occurrences of more frequent African Easterly Waves (AEWs). Therefore, the choice of the domain for regional climate model simulation of the West African summer monsoon rainfall is of critical importance, and caution needs to be taken to account for the main regional forcings including mostly the necessary humidity sources of the tropical Atlantic Ocean and the AEWs genesis region upstream of Sudanese Highlands.

Abstract:
Using the Regional Climate Model (RegCM) coupled with the Community Land Model (CLM) including modules of carbon–nitrogen cycling (CN) and vegetation dynamics (DV), this study evaluates the performance of the model with different capacity of representing vegetation processes in simulating the present-day climate over China based on three 21-yr simulations driven with boundary conditions from the ERA-Interim reanalysis data during 1989–2009. For each plant functional type (PFT), the plant pheonology, density, and fractional coverage in RegCM-CLM are all prescribed as static from year to year; RegCM-CLM-CN prescribes static fractional coverage but predicts plant phenology and density, and RegCM-CLM-CN-DV predicts plant phenology, density, and fractional coverage. Compared against the observational data, all three simulations reproduce the present-day climate well, including the wind fields, temperature and precipitation seasonal cycles, extremes, and interannual variabilities. Relative to RegCM-CLM, both RegCM-CLM-CN and RegCM-CLM-CN-DV perform better in simulating the interannual variability of temperature and spatial distribution of mean precipitation, but produce larger biases in the mean temperature field. RegCM-CLM-CN overestimates leaf area index (LAI), which enhances the cold biases and alleviates the dry biases found in RegCM-CLM. RegCM-CLM-CN-DV underestimates vegetation cover and/or stature, and hence overestimates surface albedo, which enhances the wintertime cold and dry biases found in RegM-CLM. During summer, RegCM-CLM-CN-DV overestimates LAI in south and east China, which enhances the cold biases through increased evaporative cooling; in the west where evaporation is low, the albedo effect of the underestimated vegetation cover is still dominant, leading to enhanced cold biases relative to RegCM-CLM.

Abstract. To model stratocumulus clouds in the regional climate model, RegCM4.1, the University of Washington (UW) turbulence parametrization has been coupled to RegCM. We describe improvements in RegCM's coastal and near-coastal climatology, including improvements in the representation of stratiform clouds. By comparing output from a 27-yr (1982–2009) simulation of the climate of western North America to a wide variety of observational data (station data, satellite data, and aircraft in situ data), we show the following: (1) RegCM-UW is appropriate for use in general regional climate studies, and (2) the UW model distinctly improves the representation of the marine boundary layer in RegCM. These model–data comparisons also show that RegCM-UW has a slight cold bias, a (wet) precipitation bias, a systematic low bias in the vertically-integrated liquid water content near the coast, and a high bias in the fractional cloud coverage. The model represents well the diurnal, monthly, and interannual variability in low clouds. These results show RegCM-UW as a nascent mesoscale stratocumulus model that is appropriate for stratocumulus investigations at scales ranging from hourly to decadal.

Abstract:
The characteristics of near surface air temperature and wind field over the Southeastern Levantine (SEL) sub-basin during the period 1979–2018 were simulated. The simulation was carried out using a dynamical downscaling approach, which requires running a regional climate model system (RegCM-SVN6994) on the study domain, using lower-resolution climate data (i.e., the fifth generation of ECMWF atmospheric reanalysis of the global climate ERA5 datasets) as boundary conditions. The quality of the RegCM-SVN simulation was first verified by comparing its simulations with ERA5 for the studied region from 1979 to 2018, and then with the available five WMO weather stations from 2007 to 2018. The dynamical downscaling results proved that RegCM-SVN in its current configuration successfully simulated the observed surface air temperature and wind field. Moreover, RegCM-SVN was proved to provide similar or even better accuracy (during extreme events) than ERA5 in simulating both surface air temperature and wind speed. The simulated annual mean T2m by RegCM-SVN (from 1979 to 2018) was 20.9 °C, with a positive warming trend of 0.44 °C/decade over the study area. Moreover, the annual mean wind speed by RegCM-SVN was 4.17 m/s, demonstrating an annual negative trend of wind speed over 92% of the study area. Surface air temperatures over SEL mostly occurred within the range of 4–31 °C; however, surface wind speed rarely exceeded 10 m/s. During the study period, the seasonal features of T2m showed a general warming trend along the four seasons and showed a wind speed decreasing trend during spring and summer. The results of the RegCM-SVN simulation constitute useful information that could be utilized to fully describe the study area in terms of other atmospheric parameters.

Abstract. The RegCM-CHEM4 is a new online climate-chemistry model based on the International Centre for Theoretical Physics (ICTP) regional climate model (RegCM4). Tropospheric gas-phase chemistry is integrated into the climate model using the condensed version of the Carbon Bond Mechanism (CBM-Z; Zaveri and Peters, 1999) with a fast solver based on radical balances. We evaluate the model over continental Europe for two different time scales: (1) an event-based analysis of the ozone episode associated with the heat wave of August 2003 and (2) a climatological analysis of a six-year simulation (2000–2005). For the episode analysis, model simulations show good agreement with European Monitoring and Evaluation Programme (EMEP) observations of hourly ozone over different regions in Europe and capture ozone concentrations during and after the summer 2003 heat wave event. For long-term climate simulations, the model captures the seasonal cycle of ozone concentrations with some over prediction of ozone concentrations in non-heat wave summers. Overall, the ozone and ozone precursor evaluation shows the feasibility of using RegCM-CHEM4 for decadal-length simulations of chemistry-climate interactions.

Abstract. We describe the development of a non-hydrostatic version of the regional climate model RegCM4, called RegCM4-NH, for use at convection-permitting resolutions. The non-hydrostatic dynamical core of the Mesoscale Model MM5 is introduced in the RegCM4, with some modifications to increase stability and applicability of the model to long-term climate simulations. Newly available explicit microphysics schemes are also described, and three case studies of intense convection events are carried out in order to illustrate the performance of the model. They are all run at a convection-permitting grid spacing of 3 km over domains in northern California, Texas and the Lake Victoria region, without the use of parameterized cumulus convection. A substantial improvement is found in several aspects of the simulations compared to corresponding coarser-resolution (12 km) runs completed with the hydrostatic version of the model employing parameterized convection. RegCM4-NH is currently being used in different projects for regional climate simulations at convection-permitting resolutions and is intended to be a resource for users of the RegCM modeling system.

Abstract:
Anticipating seasonal climate anomalies is essential for defining short-term adaptation measures. To be actionable, many stakeholders require seasonal forecasts at the regional scale to be properly coupled to region-specific vulnerabilities. In this study, we present and preliminarily evaluate a regional-scale Seasonal Forecast System (SFS) over Central Italy. This system relies on a double dynamical downscaling performed through the Regional-scale Climate Model (RCM) RegCM4.1. A twelve-member ensemble of the NCEP-CFSv2 provides driving fields for the RegCM. In the first step, the RegCM dynamically downscales NCEP-CFSv2 predictions from a resolution of 100 to 60 km over Europe (RegCM-d1). This first downscaling drives a second downscaling over Central Italy at 12 km (RegCM-d2). To investigate the added value of the downscaled forecasts compared to the driving NCEP-CFSv2, we evaluate the driving CFS, and the two downscaled SFSs over the same (inner) domain. Evaluation involves winter temperatures and precipitations over a climatological period (1982–2003). Evaluation for mean bias, statistical distribution, inter-annual anomaly variability, and hit-rate of anomalous seasons are shown and discussed. Results highlight temperature physical values reproduction benefiting from the downscaling. Downscaled inter-annual variability and probabilistic metrics show improvement mainly at forecast lead-time 1. Downscaled precipitation shows an improved spatial distribution with an undegraded but not improved seasonal forecast quality.

Abstract:
Les variations du rayonnement solaire en surface (SSR) peuvent avoir un impact significatif sur divers aspects du système climatique, et notamment sur le développement socio-économique d’un pays. Pour identifier les impacts possibles du changement climatique sur le rayonnement solaire en surface à l'échelle régionale (~ 50 km) en Afrique australe jusqu'à la fin du 21ème siècle, on a analysé les données mensuelles produites dans le cadre du projet CORDEX-Afrique sur la période 1979-2099. Ces données sont issues des sorties de 5 modèles régionaux de climat (RCM) forcés par 10 modèles globaux de climat (GCM) CMIP5, pour deux scénarios d’émissions, RCP4.5 et RCP8.5, en Afrique australe (SA) et sur une partie du SWIO (0-40°S ; 0- 60°E). Pour contribuer au projet futur proposé qui vise à approfondir l'étude des changements de SSR à l'échelle locale (~ 1 km de résolution horizontale) à l'île de la Réunion et à l'île Maurice, situées dans le Sud-ouest de l'océan Indien (SWIO), près du bord d’Est du domaine CORDEX-Afrique, des simulations climatiques ont été réalisées sur trois fenêtres temporelles de 10 ans : a) le passé 1996-2005 ; et b) le futur 2046-2055 et 2090-2099, en utilisant la version 4 du RCM RegCM (RegCM4), forcé par : 1) les réanalyses climatiques ERA-Interim (ERAINT) du centre européen pour les prévisions météorologiques à moyen terme (ECMWF) pour simuler un passé récent seulement ; et 2) deux GCMs (HadGEM2-ES et GFDL-ESM2M) de l’exercice CMIP5 de simulations du climat passé et futur pour le scénario d’émissions RCP8.5 à l’échelle régionale de 50km en Afrique australe et dans le sud-ouest de l’océan Indien (0-40°S ; 0- 100°E). L’analyse de l’impact du changement climatique sur le SSR sur la base de ces simulations reste cependant limitée, à cause de leur couverture temporelle (3 périodes de 10 ans) et du nombre de modèles (2 GCMs, 1 RCM) et de scénarios (1 RCP) utilisés. Il ressort de l’analyse des simulations de l’ensemble CORDEX-Afrique que : 1) sur la période passée récente, les GCMs forceurs surestiment généralement SSR d'environ 1 W/m2 en été austral (DJF : Décembre-Janvier-Février), et de 7,5 W/m2 en hiver austral (JJA : Juin-Juillet-Août), tandis que les RCMs, forcés par ces GCMs, sous-estiment SSR d'environ -32 W/m2 et de -14 W/m2 en été et en hiver, respectivement. 2) Les projections multi-modèles de changement de SSR simulées par les RCMs et leurs GCMs forceurs sont assez cohérentes. Les GCMs prévoient, en moyenne multi-modèles, une augmentation statistiquement significative de SSR d'environ 8 W/m2 en 2099 selon le scénario RCP4.5 et de 12 W/m2 en 2099 selon le scénario RCP8.5 sur le Centre de l’Afrique australe (SA-C), et une diminution de SSR, avec un degré de confiance élevé, d'environ -5 W/m2 en 2099 selon le scénario RCP4.5 et de -10 W/m2 en 2099 selon le scénario RCP8.5, pendant la saison DJF, en Afrique équatoriale (EA-E). Dans ces deux régions, les RCMs produisent, en moyenne multi-modèles, des tendances similaires (avec un degré de confiance élevé) à celles des GCMs, mais sur des zones d’extension spatiale plus faible que celle des GCMs. Cependant, pour la saison JJA, une augmentation de SSR, d'amplitude similaire dans les simulations GCMs et RCMs (~5 W/m2 en 2099 selon le scénario RCP4.5 et 10 W/m2 selon le scénario RCP8.5), est attendue dans la région EA-E. 3). Une diminution significative de la nébulosité (environ -6% en 2099) est attendue sur le continent sud-africain pour les GCMs comme pour les RCMs. 4) Le scénario RCP8.5 produit des changements d’amplitude supérieure de 2.5W/m2 pour les GCMs forceurs et de 5W/m2 pour les RCMs en 2099 à celle pour le scénario RCP4.5. 5). Comme pour les sorties du modèle RegCM4, les structures des biais ou des changements de SSR issu des RCMs du programme CORDEX-Afrique sont globalement corrélées avec celles de couverture nuageuse totale des RCMs. L’analyse des sorties du modèle RegCM4 indique que :
Changes in Surface Solar Radiation (SSR) have the potential to significantly impact diverse aspects of the climate system, and notably the socio-economic development of any nation. To identify the possible impacts of climate change on SSR at regional scales (~50 km) over Southern Africa and the South West Indian Ocean (SA-SWIO; 0-40°S ; 0- 100°E) up to the end of the 21st century, a slice downscaling experiment consisting of simulations covering three temporal windows: a) the present 1996-2005; b) the future 2046-2055 and 2090-2099 conducted with the Regional Climate Model (RCM) RegCM version 4, driven by the European Center for Medium-range Weather Forecasting (ECMWF) ERA-Interim reanalysis (ERAINT, only present) and 2 Global Climate Model (GCMs: HadGEM2-ES and GFDL-ESM2M) from the Coupled Model Intercomparison Project Phase 5 (CMIP5) under RCP8.5 scenario, are performed and evaluated. Since the slice simulation is of limited temporal coverage, number of regional and driven global models and climate change forcings, mainly because of the limit of available computational resources, the study towards a comprehensive knowledge of SSR changes in context of climate change is thus extended: an ensemble consisting of outputs from 20 regional climate downscaling realisations based on 5 RCMs that participated in the Coordinated Regional Downscaling Experiment (CORDEX) program (CORDEX-Africa) along with their 10 driving GCMs from CMIP5 covering southern Africa (0-40°S; 0- 100°E) during the period of 1990-2099 is analyzed under RCP4.5 and RCP8.5 up to 2099.The slice experiment indicates that 1) RegCM4 simulates present-day seasonal climatology, (surface air temperature, precipitation and SSR) quite well, but has a negative total cloud cover bias (about -20% in absolute percentage) when forced by the ERAINT and the two GCMs. 2) Internal variability of RegCM4-simulated annual means SSR (about 0.2 W/m2) is of one order smaller than the model bias compared with reference data. 3) RegCM4 simulates SSR changes in opposite signs when driven by the different GCMs under RCP8.5 scenario. 4) Electricity potential calculated using first-order estimation based on the RegCM simulations indicates a change less then 2% to 2099 with respect on present level.It is also found from the ensemble study that: 1) GCMs ensemble generally overestimates SSR by about 1 W/m2 in austral summer (December, January, and February, short as DJF) and 7.5 W/m2 in austral winter (June, July and August, short as JJA), while RCMs ensemble mean shows underestimations of SSR by about -32 W/m2 and -14 W/m2 in summer and winter seasons respectively when driven by GCMs. 2) Multi-model mean projections of SSR change patterns simulated by the GCMs and their embedded RCMs are fairly consistent. 3) GCMs project, in their multi-model means, a statistically significant increase of SSR of about 8 W/m2 in RCP4.5 and 12 W/m2 in RCP8.5 by 2099 over Centre Southern Africa (SA-C) and a highly confident decreasing SSR over Eastern Equatorial Africa (EA-E) of about -5 W/m2 in RCP4.5 and -10 W/m2 in RCP8.5 during the DJF season. RCMs simulate SSR change with statistical confidence over SA-C and EA-E area as well with a little spatial extension compared to GCMs. However, in the JJA season, an increase of SSR is found over EA-E of about 5 W/m2 by 2099 under RCP4.5 and 10 W/m2 under RCP8.5, of similar amplitudes in both the GCMs and RCMs simulations. 4) Significant cloudiness decrease (about -6 % to 2099) is found over continent of SA for GCMs and also shown in RCMs. 5) Larger SSR changes are found in the RCP8.5 scenario than in the RCP4.5 scenario in 2099, with about 2.5 W/m2 enhanced changes in GCMs and about 5 W/m2 in RCMs. 6) Either the biases or the changes pattern of SSR are overall correlated with the patterns of total cloud cover from RCMs in CORDEX-Africa program (for RegCM4 as well).

Abstract:
The work presented in this thesis document reflects the results of a study carried out to better quantify the magnitude and fate of the anthropogenic air pollutants emitted from East Asia. Simulations of anthropogenic sulfur compounds by a regional on-line coupled chemistry-climate model suggest that large portions of East Asia have high SOx concentrations, and most subregions within East Asia are net exporters of SOx (SO2+SO4) (i.e. the anthropogenic S emissions from the region are greater than the deposition to the region). Among them, China is responsible for ~ 85% of the total emissions, and ~ 50 % of its total emitted SOx is exported to locations outside its borders. During the later winter to early spring when the continental outflow conditions predominate, about 20% of the total emitted SOx within the investigated area has been exported to North Pacific Ocean based on our model simulations. Those exported anthropogenic SOx from East Asia (mainly in the form of sulfate) is likely large enough to perturb the sulfate aerosol concentration over the North Pacific Ocean. Our investigation by integrating numerical simulations through a regional off-line full chemistry transport model, which is driven by the meteorological conditions calculated by a regional climate model, with field measurements of both gaseous and particulate species at a rural site adjacent to the largest industrialized area in China suggests that CO emissions from China, especially eastern China are likely underestimated by ~ 50 % in the current East Asia anthropogenic emission inventories. In addition, a 60-90 % underestimation of particulate carbonaceous emission in the inventories is suggested. Further statistical diagnoses, together with the back-trajectory analysis show that the missing CO sources are likely associated with SO2 sources that are already accounted for in the current inventories. This in turn suggests the emission factors of coal-combustors used in the current inventories are likely underestimated.

Abstract:

The aim of this Master´s thesis is to examine which type of regime the state Iran is. There has been much research on this issue and the discussion is not over yet. I have departed from three theoretical perspectives in order to understand which type of regime the Middle Eastern nation is: theocracy, democracy and hybrid regime. The theocratic regimetype is composed by David L. Websters archeological theory about governments ruled by God. For the democratic theory in this study Robert Dahls analytical framework about democracy and polyarchy is used. The hybrid regime is mainly represented by Andreas Schedler indicators. A qualitative case study approach is used for the purpose of this study where I have constructed an analytical framework containing indicators in order to apply these on the three regime models. The results and conclusion I can draw from this study is that Iran is more like a hybrid regime. However, there are several reservations and there need to be more studies to qualify this suggestion.

This paper focuses on the role freedom plays in Michel Foucault’s analyze of liberal and particularely neoliberal governmentalities. From his perspective, neoliberalism operates through the strategic production of entrepreneural subjectivity and distribution of self-governing. Here autonomy is central for governing, which raises questions about what freedom can mean at all in Foucault, and how resistance can be possible. Through Foucault’s thinking on liberal freedom, we can gain a better understanding of his philosophy on subjectivation and resistance.

Abstract:
Physical pressure caused by human activity is a significant and growing environmental problem that has a major impact on aquatic environments and habitats. To deal with this problem, the EU Water Framework Directive demands that hydromorphological status assessment of surface waters be implemented by all member states as part of the ecological status assessment. The aim of this thesis was to develop a method for assessing the hydromorphological status in lakes and coastal waters of Åland in accordance with the WFD guidelines, and to perform the status assessment of two water bodies according to the developed method.  An evaluation manual based on three quality factors – connectivity, hydrological regime and morphological conditions – and associated parameters was developed from a combination of WFD parameters, Swedish and Finnish assessment criteria and custom solutions. The assessment parameters were adapted to local conditions as well as available data and the assessment was conducted using GIS to ensure consistent and time-efficient execution. In accordance with the developed manual, the assessment was carried out for the coastal water body, Västra Hamnen, and Lake Långsjön. Lake Långsjön received a hydromorphological status of “good”, the primary pressure being a small regulation dam adjacent to the water body. As expected, Västra Hamnen showed a greater physical impact due to hydrodynamic effects caused by ship traffic and a road embankment, as well as a greater morphological impact due to artificial shoreline and land use in the surrounding area. As a result, Västra Hamnen received a hydromorphological status of “unsatisfactory”. The results of the project show that an assessment of the hydromorphological status of the surface waters of Åland is not only possible with the data currently available, but can be conducted in a resource and time efficient way using GIS and will facilitate the assessment of all of Åland’s lakes and coastal waters according to WFD guidelines. This report will: form the basis for reporting to the EU; account for both the methodology that will be used for hydromorphological status assessment on Åland and for the outcome of the assessment of the selected water bodies; and provide guidance for the further assessment of hydromorphological status. The method used has a promising future in development and extension opportunities as new research becomes available, and will put Åland at the forefront of hydromorphological assessment in Europe.

Esta dissertação é dedicada à compreensão do processo de imigração dos brasileiros para Portugal. Optou-se por abordar as motivações resultantes de fatores de ordem legal que levaram imigrantes a escolherem Portugal como país de destino. Propõe-se um foco no Brasil, associado ao papel executado pelo Estado, tanto brasileiro quanto português nesta questão. Recorreu-se à revisão teórica sobre a imigração, ao histórico da imigração brasileira para Portugal, às medidas legais que propiciaram a imigração dos brasileiros para Portugal e, por fim, às possíveis implicações que podem ocorrer nos processos de imigração devido à propagação da pandemia de COVID-19.
This dissertation is aimed at understanding the immigration process of Brazilians to Portugal We chose to address the motivations resulting from legal factors that led immigrants to choose Portugal as their destination country. It is focused on Brazil associated with the role played by the State, both Brazilian and Portuguese in this matter. Theoretical review on immigration was used, the history of Brazilian immigration to Portugal, the legal measures that led to the immigration of Brazilians to Portugal and, finally, the possible implications that may occur to the immigration processes due to the spread of the pandemic COVID-19.

Abstract:
Global Ocean Governance (GOG) är till för att styra och organisera aktörers nyttjande av havens resurser som inte täcks av nationell lagstiftning på ett hållbart sätt. Men efter årtionden av staters förbiseende av regimen för ett hållbart nyttjande som främst FNs Generalförsamling (UNGA) ämnat skapa, har regimen inte fungerat. Även om stater rationellt skulle gynnas av att samarbeta för ett hållbart nyttjande av havens resurser genom ett moratorium av bottentrålfiske i internationellt vatten, har detta inte skett. Det är alltså tydligt att regimen inte fungerar. Frågan är varför - det vill säga hur regimen brister i att säkerställa ett hållbart nyttjande av havens resurser. För att ta reda på hur regimen brister krävs en undersökning av regimens (in)effektivitet.Det finns ingen konsensus mellan regimteoretiker av vad som utgör en (in)effektiv regim och hur en regims effektivitet kan mätas. Denna studies huvudsakliga bidrag till den vetenskapliga forskningen är att bidra med information om vad som utgör en effektiv respektive ineffektiv regim. Denna studies syfte är inte att ta reda på denna fråga, men att genom analysen om hur regimen av ett moratorium av bottentrålfiske i internationellt vatten brister, bidra till den vetenskapliga forskningen utifrån teorikonsumtion.Genom Greenes (1996) kriterier för vad som utgör en (in)effektiv regim har jag undersökt hur regimen, dess skapande institutioner samt regimens omgivning, brister. Ett viktigt resultat av min analys är att UNGA brister på grund av sin försiktighet att styra staters beteende genom en global regim, det vill säga betoningen av dess resolutioner i frågan om ett moratorium mot bottentrålfiske i internationellt vatten är bristfälliga.
The main task of Global Ocean Governance (GOG) is to govern and organize actor’s exploitation of the resources that the seas that are not covered by national jurisdiction provide, in a sustainable manner. But after decades of state’s ignorance towards theregime on a sustainable use of the resources of the seas that the United Nation’s General Assembly (UNGA) has been aiming to create, the regime has shown to be dysfunctional.Even if states would benefit rationally from cooperation for a sustainable use of the resources that the seas provide through a moratorium on bottom trawling of the high seas, such cooperation is not in place. It is clear that the regime is dysfunctional. The question is why – that is, in what way the regime is insufficient in providing a sustainable use of the resources of the high seas. In order to analyse why the regime is flawed, an evaluation of the regime’s (in)efficiency is required.There is no consensus among regime theorists of what makes an (in)effective regime and how a regime’s effectiveness can be measured. The main scientific contribution of this study is to contribute with information on what criteria makes an effective or an ineffective regime. The purpose of this study is not to examine this question per se, but to, through the analysis of how the regime on a moratorium of bottom trawling in the high seas is lacking, provide to the scientific regime discussion through theory consumption.Through Greene’s (1996) criteria on what makes a regime (in)effective, I have analysed how the regime, it’s creator’s, and the surroundings of the regime, fails. A key- finding of my analysis is that UNGA fails because of its caution to steer state’s behaviour through a regime, that is, the stress of its resolutions for a moratorium on bottom trawling in the high seas are lacking.

Abstract:
New simulation results, obtained from the chemical version of the regional climate model RegCMCHEM4, are presented for Siberian region. The verification of the chemical subsystem of the model with non-hydrostatic dynamical core is carried out using the atmospheric chemical transfer scheme CBMZ (Carbon Bond Mechanism-Z). To define chemical emissions the global RCP (Representative Concentration Pathways) emission dataset prepared by the International Institute for Applied Systems Analysis (IIASA), is used. For gas phase species, we have prepared the 6 hourly chemical boundary conditions from our modified version of the Model for Ozone and Related chemical Tracers, version 4 (MOZART-4). Quantitative estimates of methane emission in the atmosphere of the Siberian region have been obtained.

Abstract:
The paper considers the behavior of total methane content in the atmosphere of Western Siberia obtained using the global chemical transport model MOZART-4 (Model for OZone And Related chemical Tracers, version 4). We discuss details of the model configuration for simulation of methane content until the end of the XXI century within the Representative Concentration Pathways (RCP4.5 and RCP8.5). Boundary conditions at the lower levels of the model (methane content in the surface air layer) was obtained using data from the Earth System Research Laboratories (ESRL) project and the results of the Atmospheric Chemistry-Transport Models (ACTM) for 2007–2010. The methane content in the stratosphere was also defining according to the ACTM results. The climate data used in MOZART-4 is based on the results of the Goddard Earth Observing System, Version 5 (GEOS-5). The modification of the boundary conditions carried out in the work made it possible to reproduce the summer and winter maximum in the annual course of CH4. These results are confirmed by satellite and aircraft observations made on the territory of Western Siberia. It was found that the total methane content in the atmosphere of the studied region (45–65 N, 60–90 E) in 2000–2020 increased with a trend of about 3.5 ± 0.2 ppb/year. In 2000–2006, there is virtually no trend. The increase of CH4 in 2007–2020 has a trend of ∼ 5.0 ± 0.2 ppb/year. The global data obtained as a result of the simulation can be used as initial and boundary conditions of the chemical version of the regional climate model RegCM-CHEM4.
