A dense rain-gauge network within continental Ecuador was used to evaluate the quality of various products of rainfall data over the Pacific slope and coast of Ecuador (EPSC). A cokriging interpolation method is applied to the rain-gauge data yielding a ...

Sendo a variável mais importante no ciclo hidrológico, a precipitação nos trópicos possui grande influência na circulação atmosférica, pois uma parte da energia gerada de tal circulação provem do calor latente que é originado da precipitação tropical. O ...
