Resumo: This paper presents an analysis of the thermodynamic structure of the atmosphere with the processes related to a thunderstorm occurred on 17 and 18 March 2013 in the State of Rio de Janeiro. The coupling of a stationary cold front in the Atlantic Ocean with a moisture channel over western central Brazil, resulted in elevated precipitation in the northern part of the Metropolitan Region of Rio de Janeiro (MARJ) and of the surroundings areas (northward highlands). Among the consequences caused by this event are: landslides and urban floods, 34 deaths and material damage. The result was obtained from analysis of radiosonde data, which indicated strong conditional instability, presence of strong advection hot air and wet associate with wind shear in the surface boundary layer, as registered in the International Airport Tom Jobim in late afternoon of March, 17th 2013. The thermodynamic conditions was plenty favorable to the organization and maintenance of deep forced convection, which provided alarming values of precipitation.

Argumenta-se que o acoplamento entre uma frente fria sobre o Oceano Atlântico e um canal de umidade estabelecido sobre o centro-oeste brasileiro resultou na formação de precipitações elevadas na parte norte da Região Metropolitana do Rio de Janeiro (RMRJ) e também na Região Serrana do RJ. Entre as consequências provocadas por este evento tem-se: deslizamentos de encosta e enchentes urbanas, 34 mortes e vultosos prejuízos. Dados de radiossondagens indicaram forte instabilidade condicional no dia 17/Mar/2013, associada intensa advecção de ar úmido e forte cisalhamento do vento de sul na Camada Limite Superficial (CLS) sobre a RMRJ. As condições termodinâmicas favoreceram a organização e manutenção de convecção forçada associada ao desenvolvimento vertical de uma tempestade na noite de 17 para 18/Mar/2013, sobre a Região Serrana.Universidade Federal do Rio de Janeiro2014-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/697110.11137/2014_1_17_26Anuário do Instituto de Geociências; Vol 37, No 1 (2014); 17-26Anuário do Instituto de Geociências; Vol 37, No 1 (2014); 17-261982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6971/5538Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSousa, Frank Bruno Baima deKaram, Hugo Abi2017-01-23T22:42:35Zoai:www.revistas.ufrj.br:article/6971Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T22:42:35Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
