Influência Das Condições Do Solo Na Climatologia Da Previsão Sazonal Do Modelo Eta

Abstract: Modelos numéricos têm importante papel na previsão de tempo e clima, amparando assim as tomadas de decisões em diversos setores. O aprimoramento destes modelos pode ser feito a partir de parametrizações de processos de superfície, como o balanço de umidade do solo. Esse balanço é obtido a partir de parâmetros hidrológicos definidos para cada tipo de solo, e pela umidade inicial inserida no modelo. O objetivo desse trabalho é estudar a influência das condições iniciais do solo e do tipo de solo na previsão sazo… Show more

“…() verified that heavy daily precipitations in summer season occur in a region between Brazil, Argentina and Uruguay, in the Eastern subtropical region of the La Plata Basin, where strong coupling between the soil moisture memory and evapotranspiration occurs. Modelling studies verified that the soil moisture conditions in this basin also determine the location and magnitude of precipitations in different seasons of the year (Rozante and Cavalcanti, ; Doyle et al ., ; Resende and Chou, ). In summer, besides precipitation recycling, the soil moisture also influences the mesoscale circulation patterns, because their effect over the energy balance influences the NAL and, consequently, the LLJ (Cavalcanti et al ., ).…”

“…Several studies evaluated the Eta model skills in different configurations [1,[22][23][24][25][26][27][28][29][30]. Some works have investigated the Eta model skills over some parts of the Sao Francisco River basin on a seasonal scale [31][32][33]. [31] used seasonal forecasts of the Eta model between November and February from 2001 to 2010.…”

“…O modelo ETA tem sido utilizado pelo INPE para produzir previsões em alta resolução, para previsões de tempo (CHOU, 1996;SELUCHI et al, 2003;SELUCHI et al, 2003;VIEIRA et al, 2015;SIQUEIRA et al, 2016), clima sazonal (CHOU et al, 2005;PILOTTO et al, 2012;RESENDE et al, 2015) e clima subsazonal (CHOU et al, 2005). O INPE tem usado os modelos globais do Painel Intergovernamental sobre Mudanças Climáticas (IPCC) do Quinto Relatório de avaliação (AR5), modelos do Japão (MIROC5) e do Reino Unido (HadGEM2-ES) para rodar o ETA 20km para os cenários RCP 4.5 (emissões medias) e RCP 8.5 (altas emissões), até 2100.…”
