Resumo: | The Priestley-Taylor coefficient (α) was calculated based on the Bowen method evapotranspiration estimative for Vochysia divergens monospecific forests in Pantanal, Brazil. The study area was located at the northeastern Pantanal, approximately 160 km from Cuiabá city, Mato Grosso State, Brazil (16º39'50''S; 56º47'50''W). Continuous micrometeorological flux measurements at a 32 m tower height were made from January to December of 2007. The evapotranspiration ranged from 2.26 mm day-1 (dry season) to 4.50 mm day-1 (wet season). The average estimated α value ranged along the year from a maximum and a minimum during the dry and wet season respectively, with an annual average of 0.65±0.18 according to the weather pattern over the study area due to the increase of water content in soil/water flooding depth and/or decrease in evaporative demand. Based on empirical α values, estimates of evapotranspiration can be improved for Vochysia divergens forests on Pantanal floodplain. |

A área em estudo estava localizada no noroeste do Pantanal a aproximadamente 160 km de Cuiabá, Mato Grossso, Brasil (16º39'50''S; 56º47'50''O). Medições micrometeorológicas contínuas, em uma torre a uma altura de 32 m de altura, foram feitas de janeiro a dezembro de 2007. A evapotranspiração variou de 2,50 mm dia-1 (estação seca) a 4,10 mm dia-1 (estação úmida). O coeficiente Pristley-Taylor (α) variou durante o ano com valores máximos e mínimos nas estações seca e úmida, respectivamente, com média anual de 0,65 ± 0,18 de acordo com o padrão climático da área em estudo em função do aumento do conteúdo de água no solo/lâmina d'água de inundação e/ou diminuição na demanda evaporativa. Com a determinação empírica das dimensões de α, as estimativas da evapotranspiração podem ser melhoradas para florestas de Vochysia divergens na planície de inundação do Pantanal.Sociedade Brasileira de Meteorologia2020-03-04T17:51:46Z2020-03-04T17:51:46Z2010info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSANCHES, L. et al.
