Abstract:
In this paper, the possible connection between the frequency of Atlantic hurricanes to the climate change, mainly the variation in the Atlantic Ocean surface temperature has been investigated. The correlation between the observed hurricane frequency for different categories of hurricane’s intensity and Sea Surface Temperature (SST) has been examined over the Atlantic Tropical Cyclogenesis Regions (ACR). The results suggest that in general, the frequency of hurricanes have a high correlation with SST. In particular, the frequency of extreme hurricanes with Category 5 intensity has the highest correlation coefficient (<i>R</i>&amp;thinsp;=&amp;thinsp;0.82). In overall, the analyses in this work demonstrates the influence of the climate change condition on the Atlantic hurricanes and suggest a strong correlation between the frequency of extreme hurricanes and SST in the ACR.

Abstract:
Abstract Overall activity during the 2011 eastern North Pacific hurricane season was near average. Of the 11 tropical storms that formed, 10 became hurricanes and 6 reached major hurricane strength (category 3 or stronger on the Saffir–Simpson hurricane wind scale). For comparison, the 1981–2010 averages are about 15 tropical storms, 8 hurricanes, and 4 major hurricanes. Interestingly, although the number of named storms was below average, the numbers of hurricanes and major hurricanes were above average. The 2011 season had the most hurricanes since 2006 and the most major hurricanes since 1998. Two hurricanes affected the southwestern coast of Mexico (Beatriz as a category 1 hurricane and Jova as a category 2 hurricane), and the season’s tropical cyclones caused about 49 deaths. On average, the National Hurricane Center track forecasts in the eastern North Pacific for 2011 were very skillful.

Abstract:
Abstract Wind stress imposed on the upper ocean by a hurricane can limit the hurricane’s intensity primarily through shear-induced mixing of the upper ocean and subsequent cooling of the sea surface. Since shear-induced mixing is a one-dimensional process, some recent studies suggest that coupling a one-dimensional ocean model to a hurricane model may be sufficient for capturing the storm-induced sea surface temperature cooling in the region providing heat energy to the hurricane. Using both a one-dimensional and a three-dimensional version of the same ocean model, it is shown here that the neglect of upwelling, which can only be captured by a three-dimensional ocean model, underestimates the storm-core sea surface cooling for hurricanes translating at &lt;∼5 m s−1. For hurricanes translating at &lt;2 m s−1, more than half of the storm-core sea surface cooling is neglected by the one-dimensional ocean model. Since the majority of hurricanes in the western tropical North Atlantic Ocean translate at &lt;5 m s−1, the idealized experiments presented here suggest that one-dimensional ocean models may be inadequate for coupled hurricane–ocean model forecasting.

Abstract:
Abstract Hurricanes Bertha of 1996 and Erin of 2001 both intensified rapidly during part of their time over the North Atlantic. A piecewise potential vorticity (PV) inversion is applied to model output from GFDL hurricane model forecasts to determine the contributions of atmospheric features in the hurricanes’ environment to their intensification. The diagnosis indicates that Hurricane Bertha’s rapid intensification was directly augmented by an upper-level trough to the north. The significant positive impact of the trough provides quantitative confirmation of the inference of other authors. By contrast environmental interactions associated with troughs to the east and west of Hurricane Erin did not contribute directly to its rapid intensification. The implication of this result is that factors other than the troughs, including sea surface temperature, were sufficient to effect Hurricane Erin’s strengthening. Enhanced upper-level outflow concentrated northeast of the hurricane’s center that was associated with upper-level PV features to the north of Erin, including those ahead of the long-wave trough to its west, could have had some indirect contribution to its intensification. The present authors’ previous piecewise inversion applied to a model forecast of Hurricane Opal of 1995 indicated that an approaching upper-level trough did not significantly contribute to the hurricane’s lower-tropospheric intensification. The conclusions of this paper demonstrate that this result is neither an exception nor the rule.

Abstract:
Hurricane Katrina, followed by Hurricane Rita, were some of the most destructive and costliest hurricanes in US history. In addition to causing death and destruction, Hurricanes Katrina, Rita, and Wilma gave rise to an epidemiology of fear.1 Despite the fact that the odds of dying in a hurricane remains low compared to that of motor vehicle crashes, tornadoes, and fires,2–3 the fear of hurricanes was reinforced by disturbing images on television. Often, these images replaced rational thinking. Teachers and public health educators worldwide only had limited materials to educate their students on the risk and risk factors for hurricanes and disasters, demonstrating how poorly the scientific community was prepared to deliver basic scientific facts about hurricanes.

Abstract:
The 2004 Atlantic basin hurricane season was one of the most active on record with nine hurricanes and six major hurricanes (maximum sustained winds &gt; 49 ms1) forming during the season. All six major hurricanes formed during August and September, causing this two-month period to be the most active on record. The primary reason the 2004 hurricane season will be remembered, however, is because of the four hurricanes that devastated the Caribbean and the southeastern United States (Hurricanes Charley, Frances, Ivan, and Jeanne). Estimated total U.S. hurricane damage was between $40 and $50 billion, and much additional damage was sustained in the Caribbean. It is shown that a very strong central Atlantic equatorial trough, associated with anomalously warm tropical Atlantic sea surface temperatures and anomalously weak tropospheric vertical wind shear, combined with extremely favorable midlatitude steering conditions to allow many of the Africa-spawned easterly waves to develop into major hurricanes in the central Atlantic. These major hurricanes then moved on long west-northwest tracks that brought them through the Caribbean and across the southeastern U.S. coastline. The very active and destructive 2004 Atlantic basin hurricane season is attributed to two primary features: a strong Atlantic equatorial trough and steering currents that caused hurricanes to track westward across the U.S. coastline.

Abstract:
Hurricanes are devastating natural disasters which dramatically modify the physical landscape and alter the socio-physical and biochemical characteristics of the environment, thus exposing the affected communities to new environmental stressors, which persist for weeks to months after the hurricane. This paper has three aims. First, it conceptualizes potential direct and indirect health effects of hurricanes and provides an overview of factors that exacerbate the health effects of hurricanes. Second, it summarizes the literature on the health impact of hurricanes. Finally, it examines the time lag between the hurricane (landfall) and the occurrence of diseases. Two major findings emerge from this paper. Hurricanes are shown to cause and exacerbate multiple diseases, and most adverse health impacts peak within six months following hurricanes. However, chronic diseases, including cardiovascular disease and mental disorders, continue to occur for years following the hurricane impact.

Abstract:
We study collective attention paid towards hurricanes through the lens of n-grams on Twitter, a social media platform with global reach. Using hurricane name mentions as a proxy for awareness, we find that the exogenous temporal dynamics are remarkably similar across storms, but that overall collective attention varies widely even among storms causing comparable deaths and damage. We construct ‘hurricane attention maps’ and observe that hurricanes causing deaths on (or economic damage to) the continental United States generate substantially more attention in English language tweets than those that do not. We find that a hurricane’s Saffir-Simpson wind scale category assignment is strongly associated with the amount of attention it receives. Higher category storms receive higher proportional increases of attention per proportional increases in number of deaths or dollars of damage, than lower category storms. The most damaging and deadly storms of the 2010s, Hurricanes Harvey and Maria, generated the most attention and were remembered the longest, respectively. On average, a category 5 storm receives 4.6 times more attention than a category 1 storm causing the same number of deaths and economic damage.

Abstract:
Abstract The 2005 Atlantic hurricane season was the most active of record. Twenty-eight storms occurred, including 27 tropical storms and one subtropical storm. Fifteen of the storms became hurricanes, and seven of these became major hurricanes. Additionally, there were two tropical depressions and one subtropical depression. Numerous records for single-season activity were set, including most storms, most hurricanes, and highest accumulated cyclone energy index. Five hurricanes and two tropical storms made landfall in the United States, including four major hurricanes. Eight other cyclones made landfall elsewhere in the basin, and five systems that did not make landfall nonetheless impacted land areas. The 2005 storms directly caused nearly 1700 deaths. This includes approximately 1500 in the United States from Hurricane Katrina—the deadliest U.S. hurricane since 1928. The storms also caused well over $100 billion in damages in the United States alone, making 2005 the costliest hurricane season of record.

Abstract:
Abstract An investigation is conducted to determine how improvements in observing capabilities and technology may have affected scientists’ ability to detect and monitor Saffir–Simpson Hurricane Wind Scale Category 5 hurricanes in the Atlantic Ocean basin during the mid-twentieth century. Previous studies state that there has been an increase in the number of intense hurricanes and attribute this increase to anthropogenic global warming. Other studies claim that the apparent increased hurricane activity is an artifact of better observational capabilities and improved technology for detecting these intense hurricanes. The present study focuses on the 10 most recent Category 5 hurricanes recorded in the Atlantic, from Hurricane Andrew (1992) through Hurricane Felix (2007). These 10 hurricanes are placed into the context of the technology available in the period of 1944–53, the first decade of aircraft reconnaissance. A methodology is created to determine how many of these 10 recent Category 5 hurricanes likely would have been recorded as Category 5 if they had occurred during this period using only the observations that likely would have been available with existing technology and observational networks. Late-1940s and early-1950s best-track intensities are determined for the entire lifetime of these 10 recent Category 5 hurricanes. It is found that likely only 2 of these 10—both Category 5 landfalling hurricanes—would have been recorded as Category 5 hurricanes if they had occurred during the late-1940s period. The results suggest that intensity estimates for extreme tropical cyclones prior to the satellite era are unreliable for trend and variability analysis.

Abstract:
Creating an accurate hurricane location forecasting model is of the utmost importance because of the safety measures that need to occur in the days and hours leading up to a storm's landfall. Hurricanes can be incredibly deadly and costly, but if people are given adequate warning, many lives can be spared. This thesis seeks to develop an accurate model for predicting storm location based on previous location, previous wind speed, and previous pressure. The models are developed using hurricane data from 1980-2009.

Abstract:
A hurricane is a combination of sustained winds, low atmospheric pressures and precipitation. Over the past decades, Louisiana has experienced several devastating hurricanes. The east bank of the City of New Orleans is bounded by Lake Pontchartrain to the North and the Mississippi River to the South. Lake Pontchartrain is a brackish system connected to the Gulf of Mexico through Lake Borgne to the East. As a Hurricane enters the Estuary from the Gulf of Mexico, it imposes a sustained surge of a few meters which may lead to flooding in areas which are not protected by levees. These flood water may be saline. Saltwater flooding is an environmental issue in flooded marshlands since saltwater can be fatal to some plants. The response of salinity and storm surge to hurricane duration which represents the forward speed of the storm is numerically modeled.

Abstract:
The development of renewable energy sources is a critical global need. The Atlantic coast and Gulf of Mexico of the U.S., with large wind resources and proximity to major population centers, are natural places for such development; however, these regions are also at considerable risk from severe hurricanes or tropical cyclones. Current international guidelines for the design of offshore wind turbines (OWTs) do not explicitly consider loading under hurricane conditions, however subsequent editions are anticipated to include language specific to hurricanes. Variability in extreme loads is greater in areas where hurricanes are likely and the design loads and risk profile of offshore structures installed in such areas are expected to be strongly influenced by hurricanes. For many offshore structures, environmental conditions at design recurrence periods and beyond are often estimated through extrapolation of long-term (i.e. multiple decades) wind and wave measurements from buoys, however, for offshore structures located at areas exposed to hurricanes, it is accepted practice to use physics-based models to augment the historical record of Atlantic hurricane activity and generate a stochastic catalog of synthetic hurricanes that provides tens of thousands of realizations for one year of potential hurricane activity. Once a stochastic catalog has been established, appropriate hazard intensity measures (e.g. the one-minute sustained wind speed, the significant wave height, and the peak spectral wave period) can be estimated for each storm at any site using well-known wind and wave parametric models. In this study, we consider several sites along the Atlantic coast and quantify the impact of estimating hazard for design recurrence periods and beyond for three different methods. The first is based on an extrapolation of wind and wave measurements from buoys, and the second and third are based on a stochastic catalog of synthetic hurricanes with wind and wave intensities estimated based on deterministic and probabilistic relationships.

Abstract:
In the past few years there have been several large hurricanes in the Gulf of Mexico that have destroyed or damaged over 200 fixed offshore platforms. These include hurricanes lvan (2004), Katrina (2005) and Rita (2005). Prior to these, the most recent hurricane to cause this level of damage was hurricane Andrew in 1992. Below water damage consisted of separated underwater braces, buckled braces, broken legs, and cracked connections. Above water damage consisted of wind and wave damage to decks and topsides equipment. Interestingly there has been little if any pile damage in any of these hurricanes. Although some newer platforms suffered damage and even destruction, most of the destroyed and damaged platforms were of older vintage and designed to American Petroleum Institute (API) Recommended Practice 2A-WSD (RP2A) practices that have since been improved. This paper summarizes the types of damage and destruction that has been found, including likely causes. It describes how some of this damage correlates to API design procedures. The work is based upon a series of projects funded by the Minerals Management Service (MMS) to study the effects of hurricanes on these types of offshore facilities.

Abstract:
A probabilistic metocean model for hurricane conditions is briefly described. The model is based on site-specific, hindcast data and defines the time variation of the metocean conditions during the realisation of a hurricane at the site. The annual extreme value distribution of mooring line tension for a large, semi-submersible, mobile drilling unit is computed. Time domain analysis is applied to obtain the short-term, extreme value distribution of line tension, conditional on stationary metocean conditions. A large number of different conditions are considered. A response surface is used to interpolate on the short-term distribution parameters in order to describe the tension response during the varying conditions associated with the passage of a hurricane. The hurricane duration is split into a sequence of 15-minute intervals such that the conditions can be assumed stationary during each such short interval. The tension distribution, conditional on the realisation of a hurricane, is accumulated across the sequence of short intervals. The distribution of hurricanes is taken into account to obtain the tension distribution in a random hurricane. Finally, the frequency of hurricanes is taken into account to give the annual extreme distribution of line tension. The characteristic tension computed using 10-year return conditions and the ISO 19901-7 design standard is found to correspond to a return period of 29 years in the test case. The effects of various assumptions in the design analysis are investigated. Sensitivities to simplifications of the metocean model are considered. The effects of uncertainties in the response calculation and in the distribution of peak significant wave height during hurricanes are quantified and included in the response analysis.

Abstract:
<p>Electrical power systems are critical to the wellbeing of our economy and society. Collapse of electrical transmission towers under hurricanes may result in significant interruptions of power systems. This research proposes a framework for the development of collapse fragility curves of transmission towers subjected to hurricanes. Incremental dynamic analysis (IDA), originally established for earthquake engineering applications, is adapted to model the hurricane induced collapse behavior. For a specific site, a set of hurricane wind speed and direction records are selected from 10,000-year synthetic hurricanes using a combination of autoencoder and k-means clustering. The autoencoder first compresses each wind record into 5 latent features, to which the k-means clustering is applied. Thus, all the collected wind records are divided into 4 clusters. Twenty wind records are picked at random from the 4 clusters and employed to run the IDA analysis, through which the collapse behavior is simulated, incorporating uncertainties in wind loading. The intensity measure of fragility curves is the storm maximum gust wind speed, and therefore the fragility curve is given as the cumulative distribution function (CDF) of the collapse capacity, which is designated as the intensity measure at the onset of collapse. The parameters of a fragility curve are estimated from the simulated data of the collapse capacity using the method of moments. The developed fragility curves are helpful in damage prediction of the electrical power systems under hurricanes.</p>

Abstract:
This paper addresses two questions critical for the successful real world application of the Cooperative Research on Extreme Seas and their Impact (CresT) Joint Industry Project (JIP) design methodology in harsh operating environments: (1) how accurately may very extreme sea states (VESS) be specified by modern numerical spectral wave models? About 20 storms in which VESS (defined as with significant wave height (HS) > 14 m) have been measured by various in-situ and satellite-mounted altimeters are hindcast and it is shown that when the meteorological forcing is accurately specified, a proven 3rd generation (3G) wave model provides skillful and unbiased specification of peak HS and by implication of the associated spectral properties. The second question addressed is: how do current 3G models behave when applied to even more extreme meteorological forcing than observed in the real storms studied? The same hindcast methodology is, therefore, applied to a population of synthetic hurricanes whose combinations of intensity and scale are predicted by deductive modeling studies of Gulf of Mexico hurricanes carried out following Hurricane Katrina (2004). The model results suggests that for a tropical cyclone to generate say peak HS > 20 m would require the peak wind intensity of a major hurricane (Category 3 or greater) combined with a larger size and faster translation speed than may be maintained by a tropical cyclone in tropical or subtropical settings. Large scale cyclonic and relatively rapidly translating storms with major hurricane force peak wind speeds indeed exist as a class of mid-latitude extratropical cyclones, dubbed “winter hurricanes”. Hundreds of such storms have been detected in global satellite altimeter data in virtually all major ocean basins. The peak sea states in the most extreme examples are also found to be simulated quite skillfully with the hindcast technology applied. The hindcast results are explored to infer the upper limit to the naturally occurring dynamic range of sea states in tropical and winter hurricanes.

Abstract:
A wealth of Gulf of Mexico hurricane wind and wave data has been measured in recent years. We have constructed a database that combines HURDAT storm track information with NDBC buoy data for the years 1978–2010. HURDAT contains 141 storms for that period of which 67 had measured significant wave heights greater than 5 m. Industry measurements in Hurricanes Camille, Lili, Ivan, Katrina, Rita, Gustav and Ike have been added to the buoy data. We have used this data base to study the relationships between wind and wave parameters in hurricanes. Specifically, we have calculated regressions and equal probability contours for significant wave height and peak spectral periods, first and second moment periods, wave height and Jonswap gamma values, wind speeds and wave heights, and wave and wind directions. All of these calculations have been done for azimuthal quadrants of the storm and radial distances near and far from the storm center.

Abstract:
The main objective of this paper is to investigate the effects of hurricanes on low cycle fatigue of tower and blades in offshore wind turbines. For this purpose, first, recent observations on hurricane turbulence models were discussed. Second, the buffeting wind loads on the wind turbine structure were introduced. A new formulation was used to address unsteady wind forces on the tower. This new formulation was later used to modify NREL-FAST (Fatigue, Aerodynamics, Structures, and Turbulence) for the analysis. In the next step, according to importance of recent findings about hurricanes, hurricane wind and wave fields were simulated based on the Saffir-Simpson hurricane wind scale. Then, to investigate the effects of various turbulence models on the wind turbine structures, the modified NREL-FAST was used to analyze structure-wind-wave-soil interaction of the NREL-5 MW monopile wind turbine. Finally, the low cycle fatigue analysis was presented and discussed. Results for various hurricane turbulence models showed that by using quasi-steady analysis of the tower, the spectrum Model A and Model B resulted in average 53% lower and 12% higher damage index compared to the conventional Kaimal spectrum model respectively; however, by considering unsteady formulation on the tower, spectrum Model A and Model B resulted in average 96% and 24% lower blade root damage indices compared to the conventional Kaimal spectrum model respectively.

Abstract:
Installed 160 miles South of New Orleans in 1300 m of water, the Marco Polo Tension Leg Platform is subjected to an extensive monitoring campaign to benchmark design data and methods. The purpose of the full scale monitoring campaign is to evaluate the design in operation exposed to hurricane and loop-current conditions. Interests comprise the high and low frequency modes of motion, the fatigue loading of the platform and the dynamic behavior of the tendons and risers with focus on vortex induced vibrations. To evaluate these results wind, wave and current conditions are closely monitored. The monitoring system was in operation during the passage of hurricanes Ivan, Katrina and Rita. Although Marco Polo was extremely close to the center of these severe hurricanes, no significant damage was inflicted to the platform, even though wind speeds in excess of 138 mph and maximum wave heights over 28 m were measured. However, very valuable data was collected on the wave, wind, current, as well as on the response of the TLP during the Hurricane conditions.

Abstract:
We study Puerto Rico’s experience after the severe hurricane season of 2017 to better understand how extreme weather disasters affect bank stability and their ability to lend. Despite the devastation wrought by two category 5 hurricanes in a single month, we find relatively modest and transitory impacts on bank performance with no evident decline in lending capacity. We discuss various mitigants that help limit bank exposure to extreme weather and whether these mitigants may be vulnerable given the potential for more severe and more impactful climate events.

Abstract:
Caribbean Islands are exposed to hurricanes, the damages of which are projected to intensify due to anthropogenic climate change. The region is also highly indebted. We focus on the interaction between climate change, hurricanes, and public debt. We investigate what the typical impact of Caribbean hurricanes on public debt in the region has been and how anthropogenic climate change has shaped this impact. Our findings show that for the 10 most severe storms, the average increase in debt, measured as the difference between post and pre-storm trends, is about 10 percent. Three years after such a storm, debt levels are 18 percent higher than what would have been expected otherwise. Based on findings from Extreme Weather Event Attribution (EEA) research, we calculate that the impact of a severe hurricane on public debt that is attributable to climate change amounts to an increase of 3.8 percent of the debt stock relative to the level of debt at the time of the event.

Abstract:
The Marine Transportation System (MTS), Resilience Integrated Action Team (RIAT), is tasked by the coordinating board of the US Committee on the MTS to serve as a coordinating body to identify the impacts, best practices, and lessons learned by federal agencies involved in the response and recovery of the MTS after hurricane seasons. In response to this request, the RIAT has focused its analysis on the ability of MTS federal agencies to prepare, respond, recover, and adapt to as well as from disruptions. This was accomplished through workshops focused on gathering the collective experiences of emergency response professionals. In 2017, recommendations were gathered based on experiences responding to Hurricanes Harvey, Irma, and Maria. In this report, a similar approach was adopted to gather findings from Hurricanes Florence and Michael in 2018 and Hurricane Dorian in 2019. Utilizing the successes, challenges, and best practices from all six of these storms, the RIAT identified key coordinating bodies and the participants for each and key takeaways relative to the coordination of agencies with respect to the four steps of resilience: prepare, absorb, recover, and adapt.

Abstract:
Hurricanes are one of the main causes for blackouts and related infrastructure damage in the United States. Electrical transmission towers, which are key parts of the electrical transmission networks, are vulnerable to high wind speeds during storms. Collapse of transmission towers may lead to a loss of functionality of transmission lines. This research focuses on regional analysis of electrical transmission networks under hurricane hazards through developing beam elements for analyzing transmission towers, selection of hurricane wind records that incorporate uncertainty quantification, generating collapse fragility curves for transmission towers, and regional damage assessment of transmission networks.
