Padr\u00f5es t\u00edpicos do El Ni\u00f1o j\u00e1 influenciam o clima no Sul do Brasil, com previs\u00e3o de maior volume de chuvas nos pr\u00f3ximos dias<\/em><\/p>\n

O aquecimento das \u00e1guas do Oceano Pac\u00edfico Equatorial, caracter\u00edstico do El Ni\u00f1o, altera a circula\u00e7\u00e3o da atmosfera e influencia o clima em diversas partes do mundo. No Brasil, o fen\u00f4meno tende a reduzir as chuvas na Regi\u00e3o Norte e Nordeste, al\u00e9m de aumentar a frequ\u00eancia e o volume das precipita\u00e7\u00f5es na Regi\u00e3o Sul.<\/p>\n

Desde o in\u00edcio do ano, o Instituto Nacional de Meteorologia (INMET) acompanha continuamente a evolu\u00e7\u00e3o do El Ni\u00f1o para identificar o in\u00edcio de seus impactos sobre o territ\u00f3rio brasileiro. Na \u00faltima semana, observou-se a consolida\u00e7\u00e3o de padr\u00f5es atmosf\u00e9ricos t\u00edpicos do fen\u00f4meno, que favorece a ocorr\u00eancia de chuvas na Regi\u00e3o Sul.<\/p>\n

Entenda a din\u00e2mica que favorece as chuvas no Sul<\/h3>\n

Durante epis\u00f3dios de El Ni\u00f1o, ocorre o fortalecimento dos jatos de baixos n\u00edveis, que s\u00e3o correntes de vento que transportam umidade da regi\u00e3o tropical para a Regi\u00e3o Sul do Brasil. Ao mesmo tempo, a atua\u00e7\u00e3o de centros de baixa press\u00e3o nos pr\u00f3ximos dias intensificar\u00e1 o fluxo de umidade, favorecendo a forma\u00e7\u00e3o de nuvens e ocorr\u00eancia de\u00a0chuvas. Al\u00e9m disso, um sistema de alta press\u00e3o com centro no Oceano Atl\u00e2ntico e atua\u00e7\u00e3o sobre as regi\u00f5es Centro-Oeste e Sudeste, estabelece um bloqueio atmosf\u00e9rico que dificulta o avan\u00e7o dos sistemas transientes para outras regi\u00f5es do pa\u00eds. Como consequ\u00eancia, a umidade permanece concentrada sobre a Regi\u00e3o Sul, aumentando a persist\u00eancia e os volumes de chuva.<\/p>\n

Previs\u00e3o do tempo para o Sul do Brasil nos pr\u00f3ximos dias<\/h3>\n

A partir da quinta-feira (16), o aumento da umidade em baixos n\u00edveis da atmosfera e a forma\u00e7\u00e3o de instabilidades atmosf\u00e9ricas influenciam as condi\u00e7\u00f5es de tempo no Rio Grande do Sul. H\u00e1 previs\u00e3o de tempestades no sudeste ga\u00facho e na regi\u00e3o das Campanhas, com pancadas de chuva e trovoadas isoladas ao longo do dia. Nesta ultima ter\u00e7a-feira (14), o INMET emitiu um aviso de tempestade de n\u00edvel amarelo (perigo potencial), v\u00e1lido para a quinta-feira (16), abrangendo essas regi\u00f5es.<\/p>\n

Na sexta-feira (17), as condi\u00e7\u00f5es favor\u00e1veis \u00e0 ocorr\u00eancia de tempestades tornam-se mais intensas e abrangentes. Com a persist\u00eancia do aporte de umidade nas camadas mais baixas da atmosfera e o aumento da instabilidade em altitude, s\u00e3o previstas pancadas de chuva com trovoadas desde o extremo sul at\u00e9 o noroeste do Rio Grande do Sul, incluindo a Regi\u00e3o Metropolitana de Porto Alegre.<\/p>\n

No s\u00e1bado (18), al\u00e9m das condi\u00e7\u00f5es j\u00e1 descritas, a atua\u00e7\u00e3o de um centro de baixa press\u00e3o associado \u00e0 forma\u00e7\u00e3o de uma frente fria intensifica as instabilidades sobre a Regi\u00e3o Sul. Al\u00e9m das tempestades previstas para o Rio Grande do Sul ao longo do dia, o avan\u00e7o gradual desse sistema favorece a ocorr\u00eancia de pancadas de chuva no centro-sul de Santa Catarina a partir da tarde.<\/p>\n

Tamb\u00e9m nesta ultima ter\u00e7a-feira (14), o INMET emitiu um aviso de tempestade de n\u00edvel laranja (perigo), v\u00e1lido para sexta-feira (17) e s\u00e1bado (18), abrangendo boa parte do Rio Grande do Sul.<\/p>\n

Recomenda-se o acompanhamento di\u00e1rio das atualiza\u00e7\u00f5es das previs\u00f5es e dos avisos meteorol\u00f3gicos para verificar a persist\u00eancia, a intensifica\u00e7\u00e3o ou altera\u00e7\u00f5es nas condi\u00e7\u00f5es previstas.<\/p>\n
