Métodos Empíricos para Estimativa da Evapotranspiração de Referência para Morro do Chapéu-BA

The assessment of climatic, environmental, and socioeconomic aspects of the Brazilian Cerrado

“…Therefore, this location offers ideal circumstances for promoting evapotranspiration and the emergence of active fires. Santos et al (2020) examined Cerrado's annual potential evapotranspiration (ETp) in the Brazilian Northeast from 1979 to 2013. The authors detected that the greatest annual ETp rates occurred in Maranhão and Piauí States.…”

“…Moreover, Tocantins contains the lower and middle Araguaia depressions and the Araguaia River Plain/Bananal Island (Sano et al 2020). Santos et al (2020) assessed the ETp over Brazilian Northeast (northern portion of the Cerrado), and discovered that northern Maranhão (region with low-elevation, < 300 m) had the highest evapotranspiration values, with values exceeding 1250-2000 mm year −1 , while Bahia (region with elevation > 800 m) presented values ranging from 600 to 1500 mm year −1 . This behavior presented by ETp displays the importance of the elevation gradient, to which the measure that increases the elevation, there is a decrease in air temperature and relative humidity of the air, to which both contribute to the decrease of the processes inherent in ETp, corroborating with Goulden et al (2012) to which they assessed the behavior of the ETp over the Sierra Nevada in California, USA.…”
