- W2965384920 abstract "O estudo detalhado do regime das precipitações, principalmente as chuvas intensas, é muito útil, não só para a gestão dos recursos hídricos, mas também para o planejamento territorial e a previsão dos efeitos que traz para a população este fenômeno das precipitações. Este estudo tem como principal objetivo analisar as condições sinóticas do evento de chuva extrema ocorrido no município de Pelotas, RS, durante o dia 28 de janeiro de 2009. A análise sinótica das condições existentes durante esse dia demonstrou que os principais fatores para a ocorrência das chuvas intensas foram a forte convergência do vento em baixos níveis e movimentos verticais ascendentes, além de uma forte convergência de fluxo de umidade em níveis mais baixos, que resultaram ingredientes essenciais na ocorrência das precipitações. Um fato bem interessante neste caso foi que as advecções de temperatura e vorticidade foram praticamente nulas durante todo o período de formação e intensificação do ciclone extratropical Influence of the Synotic Scale in the Evolution of an Extreme Precipitation Event in the City of Pelotas - RS in January 2009 A B S T R A C TThe detailed study of the precipitation regime, mainly intense rains, is very useful not only for the management of water resources, but also for the territorial planning and prediction of the effects that this phenomenon of rainfall brings to the population. This study has as main objective to analyze the synoptic conditions the event of extreme rainfall occurred in the city of Pelotas, RS, during January 28th, 2009. The synoptic analysis of the conditions existing during this day demonstrated that the main factors for the occurrence of intense rains were the strong convergence of the wind in low levels and upward vertical movements, as well as a strong convergence of humidity flow in lower levels, which were essential ingredients in the occurrence of precipitations. A very interesting fact, in this case, was that advections of temperature and vorticity were practically null throughout the period of formation and intensification of the extratropical cyclone.Keywords: intense rainfall, natural disasters, synoptic analysis." @default.
