Resumen

Os processos hidrológicos decorrentes da interação clima-vegetação determinam os mecanismos ecológicos mais básicos. Desta forma, este artigo investigou alguns aspectos da Ecohidrologia do estado do Amazonas no período de 1959 a 2021. Foram analisadas a dinâmica espaço/temporal da precipitação total, evapotranspiração, e a retroalimentação entre estas duas variáveis, denominada de reciclagem de precipitação. Foram usados dados do produto de reanálise ERA-5 na escala de tempo mensal, mas considerando os períodos sazonais do Hemisfério Sul. Verificou-se significativa distinção sazonal nos aspectos ecohidrológicos analisados. A precipitação total e a evapotranspiração apresentaram uma relação inversa entre os períodos de maiores e menores volumes de chuva, e a reciclagem regional de precipitação pela floresta possui maior contribuição proporcional para as chuvas do setor sudoeste do estado do Amazonas em todas as estações do ano. Isso mostra a importância da manutenção da floresta em pé para a Ecohidrologia do estado do Amazonas.
