Full textThe title given to the whole work is spatial variability and statistical modelisation of rains in cisatlasic and transatlantic Morocco it is based on the data given by 16 stations from 1958 to 1987. Four different parts will be developped : - The first deals with the area which will be studied, the meteorological context, the problems raised and data used in the work. -The second part deals which the annual data after criticizing the series using the doublesmass, principal components and regression residues methods. The lacks in the data were filled by the regional vectors method. The second subdivision of this part is a statistical modelisation of the annual series by the law of Gauss which seems appropriate to explain the annual distribution over the different Moroccan stations. When the average of the annual rains is low, the distribution is normal-root. The principal components exhibits sets of stations characterised by coherent time and spatial variations. - The third deals with the monthly rains. A statistical approach of the quantity of rain higher than o,1 mn by the fuller law and also the study of the average, regimes and gradex. - The fourth part deals with the study of the daily rains approched by the fuller law (montly maxima) and the gumbel's law for the annual maxima the final results are shown in the general conclusion. The illustration is composed of : 12 maps, 98 bibliographical references, 33 drawings, 8 tables and 10 riders

Full textOur goal is to study the properties of scales invariance of rainfall observed in Tunis and their impact on the IDF and IDAF curves, a prerequisite to the design of hydraulic structures. Time series of rainfall observed in Tunis were analyzed. Several observations have been made: several regimes of scale invariance, a significant change in the fractal dimension of the support of microscale rain during the last century, non- conservative character of the regime microscale. The ‘universal multifractal’ model characterizes the statistical properties by three parameters. Taking into account the intermittent and non-conservative nature of the process of fine-scale rainfall leads to obtaining parameters in accordance with the results recently published on the properties of fine scale precipitation. The establishment of IDF curves that characterize the probability of intense events requires having observation in fine resolution (5 mn) and long periods (50 years). A regionalization relationship applied to daily data collected from DGRE on 40 raingauges in the Greater Tunis, combined with the assumption of simple scale invariance has enabled us to develop IDF curves of raingauges in the region Greater Tunis. The IDAF curves were then constructed from quantiles maps deducted from IDF curves on the one hand, from the approach proposed by De Michele in 2011 on the other

Full textThe estimation of snow storage and precipitation, essential for managing hydroelectric reservoirs of EDF, still remains subject to considerable uncertainties. EDF-DTG currently seeks to develop some tools for robust interpolations, able to provide a reliable estimate of precipitation and snow water equivalent at any point in mountainous areas. The developed tools are essentially based on the ground sensor network of DTG, which measures precipitations, snow depth and water equivalent over French mountains. In the long term, these tools should make it possible to progress towards a better spatial vision of the daily or “event” precipitation, as well as of the snow cover on the ground, based on measurements taken all over the basins requiring an operational hydrological forecast

Full textA new approach for West and East African seasonal rainfall forecasting, based on continental and atmospheric forcing predictors and the 1968-1998 homogeneous period is developed. CRU and CRC precipitation databases, NCEP/NCAR reanalyses are used for diagnoses. The West African rainy seasons are preceded by Moist Static Energy field anomalies. An inter-season memory involving soil moisture, vegetation, then MSE over Guinea is found. The East African ones are related to atmospheric dynamics signals: Indian monsoon and Walker type circulation for the short rains, Congo basin air mass intrusion and subtropical stationary waves for the long rains. A 27% explained variance gain is obtained with multiple regression, discriminant analysis and neural networks models fed with these predictors. The 2000-2001 Sahelian rainy seasons real-time forecasts made with these models were correct

Full textThe problems about research in tropical climatology are mainly the lwo density of observations post, the inequal spatial repartition of measurements and the very bad quality of some series, because of the importance of missing datas. The value of results and conclusions depend of the exactness in reviewer of existing datas and their spatial repartition. In central africa, the study of rainfall comming from the best stations in the period going from 1946 to 1985 shows the evolution and the main climatic change seen at continental and planet scale in the second half of the twentieth century. The main componment analysis allows a global approch of rainfall evolution and spatial organisation of rainfall field variability. The maps show the spatial organisation of rainfall variability field, and the graphs of annual score s on factorial axes give pictures of the chronologic rainfall flucturations. These rainfall fluctuations in the region are in closely accordance with the diversity of the physical milieu; otherwise, there is a relation between the rainfall diminution and the activity of the two actions center which deal with the spatial organisation of rainfield. The final result is a general rainfall deficiency irrelevant to the weakening of st. Helena anticyclone and the reinforcement of harmattan winds comming from sahara. In the north, the faillure of rainfall is more important than in the south. If the trend observes since 1970 continues, the monthly rainfall means which caracterise african intertropical rainfall regimes should be modified. Mainly if the normal rainfall period runs from 1970 to 2000, according to the 30 years wmo recommandations
