Análise do comportamento morfológico e radiativo de um sistema convectivo de mesoescala inferido via imagens de satélite

Abstract

ABSTRACT. This article conducts a case study describing the radiational and morphological characteristics of a Mesoscale Convective System (MCS) responsible temperatures below 210 K. The behaviour of the MCS followed that described in typical conceptual models, where early strong convection is followed by lower values of brightness temperature, and then display area expansion in its mature stage. We also found distinct relations between minimum brightness temperatures obtained from satellite imagery and precipitation rates reported at the surface during the life cycle of the MCS. The conclusion is that the data collected from only two surface stations could not allow the determination of the clear-cut agreement between the radiative characteristics of the MCS observed by satellite and precipitation rates measured at the surface.
