Approved for public release; distribution is unlimited / Under meteorological conditions associated with extreme cold air outbreaks (CAO) off the U.S. East Coast, large ocean waves sometimes develop along the North Wall of the Gulf Stream. These wave events produce wave heights above those expected given the short fetch and moderate winds. The highest waves are often very localized, which suggests localized forcing by the atmosphere. In this study, results from four cases are examined to characterize the role of high resolution, mesoscale wind forcing in generating localized regions of large ocean waves during events with large air-sea temperature differences. A known "true" atmosphere is simulated through the use of the Navy's Coupled Oceanographic and Atmospheric Mesoscale Prediction System (COAMPS). Model surface wind output from COAMPS is used to generate a wave field using Wavewatch Three (WW3), which is then compared to buoy observations and ship reports. Results of these cases show the mesoscale wind forcing of ocean waves during CAO and the importance of mesoscale atmospheric modeling in localized generation of ocean wind waves. Additionally, empirical wave forecast techniques are compared to WW3 model output for these cases to further reinforce the mesoscale atmospheric forcing during rapid growth of wind wave events in fetch limited environments. / Lieutenant Commander, United States Navy

Climatology tries to codense the many aspects of the weather during a long period into a few significant figures. The first approach is usually the calculation of mean and extreme values for a particular element over a specified period. [...]

Orientador: João Lima Sant'Anna Neto / Resumo: Nos últimos anos as mudanças climáticas têm sido foco de diversas pesquisas de cunho científico e político principalmente após as publicações dos relatórios desenvolvidos pelo IPCC. Segundo o grupo, e fato incontestável para muitos pesquisadores, as mudanças climáticas deverão aumentar consideravelmente o número e intensidade dos eventos meteorológicos extremos. Contudo, tais repercussões não ocorrerão em todos os espaços e com intensidades equivalentes. Cada grupo de acordo com o seu poder aquisitivo, forma organizacional, processo histórico e cultural percebem a eminência do risco de modo singular e, da mesma forma, em um futuro próximo, responderão de modo desigual a partir de mecanismos capazes de se precaverem com maior ou menor resiliência à essas repercussões. Diante desta discussão esta pesquisa teve o objetivo de analisar e pesquisar as repercussões dos eventos extremos, associados a temperatura (frio e calor) e condições de conforto térmico humano e bairros com diferentes padrões socioeconômicos na cidade de Presidente Prudente. A hipótese dessa pesquisa é que a população residente nos setores menos valorizados e mais segregados socio-economicamente é também a camada mais vulnerável e afetada, negativamente, por essas ocorrências extremas e com impactos significativos no conforto térmico e saúde. Para contemplar este universo de análise a pesquisa é composta por três vertentes principais: análise dos eventos extremos de frio e calor e a influência na biometeorologia...

According to the group, as well as an unquestionable fact for many researchers, climate changes should considerably increase the number and intensity of extreme weather events. However, such repercussions will not occur in all spaces and with equivalent intensities. Each group, according to their purchasing power, organizational form, historical and cultural process, perceives the eminence of risk in a unique way and, in the near future, will respond unequally through mechanisms that will be able to be cautious with more or less resilience about these repercussions. Given this discussion, this research aimed to analyze and research the repercussions of extreme events associated with temperature (cold and heat) and conditions of thermic comfort in differents socioeconomic districts in the Presidente Prudente city. The hypothesis of this research is that the population residing in the least valued and most socially and economically segregated sectors is also the most vulnerable and negatively affected by these extreme occurrences layer, with significant impacts on thermal comfort and health. In order to contemplate this universe of analysis, the research consists of three main strands: analysis of extreme cold and heat events and the influence on human biometeorology through thermal comfort and discomfort;...
