Resumo: The extreme rainfall event in November 2008 in Santa Catarina is discussed in the present study. Due to the importance of the event, the objectives of this study are: i) discuss the large scale aspects of the raifall event and ii) perform a numerical simulation using WRF Model. Synoptic analysis results show that the heavy rainfall event was associated to the persistence of a blocking high during November 2008 and a cyclonic vortex in middle-levels. The analysis of time series of meteorological variables led us to identify the origin of these atmospheric disturbances and its decay, resulting in high accumulated precipitation between November 22nd and 24th. The WRF simulation results allowed the detailing of dynamical and thermodynamic conditions that contributed to the intensity of the phenomenon. Further, it allowed the identification of the organized precipitation over the coast, even though their intensity was underestimated.

Devido à importância do evento para o Estado, os objetivos do estudo são: i) fazer uma análise sinótica do evento, utilizando-se dados da reanálise do Era Interim e ii) executar simulação com o modelo Weather and Research Forecast (WRF). A análise sinótica indica que o fenômeno de chuvas intensas analisado esteve associado à persistência de um anticiclone de bloqueio e a existência de um vórtice ciclônico em níveis médios. O acompanhamento temporal de campos de variáveis meteorológicas permitiu identificar o momento de origem e declínio dessas perturbações atmosféricas, culminando em elevados acumulados de precipitação entre os dias 22 e 24 de novembro. A simulação com o WRF permitiu maior detalhamento das condições dinâmicas e termodinâmicas que contribuíram para a intensidade do fenômeno. Além disso, a simulação permitiu um maior detalhamento dos núcleos de precipitação sobre o litoral de Santa Catarina, mesmo que a intensidade da precipitação tenha sido subestimada.Universidade Federal do Rio de Janeiro2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/783210.11137/2014_2_169_179Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 169-179Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 169-1791982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7832/6313Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlmeida, Vinícius Albuquerque deMarton, Edilson2017-02-15T17:28:22Zoai:www.revistas.ufrj.br:article/7832Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-02-15T17:28:22Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
