摘要
The temporal-spatial variation of evapotranspiration was analysed using Morlet wavelet in a forest of Vochysia divergens Pohl (locally known as Cambarazal) in Pantanal wetland in Mato Grosso state, Brazil. This area is inserted within the physiographic plain of the Pantanal and is seasonally flooded. The net radiation, solar global radiation, air temperature, and relative humidity data were collected by sensors installed in a micrometeorological tower. The daily analysis of time series by Morlet wavelet for evapotranspiration was satisfactory enabling better understanding of the dynamics of evapotranspiration in wetland and its relation to the air temperature, relative humidity, and solar radiation. It is concluded that during the wet season the highest values of evapotranspiration and higher intensity in the high frequency occured probably due to increased availability of water as a function of rainfall and flooding, and solar radiation.
