Análise espacial da influência dos elementos meteorológicos sobre a evapotranspiração de referência em Minas Gerais

Abstract: RESUMOComumente, as metodologias utilizadas e recomendadas para estimar o requerimento d'água pelas plantas são baseadas em elementos meteorológicos, razão por que o objetivo deste trabalho foi analisar a influência dos elementos meteorológicos na estimativa da evapotranspiração de referência (ET 0 ) no estado de Minas Gerais. Os valores de ET 0 foram estimados pelo método de Penman-Monteith-FAO, a partir de dados diários, referentes a um período de 17 anos. A influência de cada elemento meteorológico no valor… Show more

“…This heterogeneity is directly reflected in changes of evapotranspiration, which, associated with increases in temperature, generate higher atmospheric demand (Lemos Filho et al, 2010) impacting the water balance and agroclimatic zoning. Regarding the water balance, there were increments in DEF values and reduction in EXC values, with greater intensity in the Northwest, North and Jequitinhonha and Mucuri Valleys at the end of the XXI century in RCP 8.5 ( Figure 3A), and also for the other regions of Minas Gerais, corroborating the results of Cardoso & Justino (2014).…”

“…This tendency reflected in ET 0 values, which showed variations especially when there were variations in Rd values. According to Fietz & Fisch (2009) and Lemos Filho et al (2010), among the meteorological elements (temperature, relative air humidity and wind speed), solar radiation is the factor that most influences the value of ET 0 .…”
