Abstract

The dynamics of climatic elements, with emphasis on temperature and precipitation, are fundamental for studies on the Climate Classification Systems (CCS) of a region, as well as for determining the Climatological Water Balance (BHC). Thus, the objective of the work was to determine the Climatological Water Balance and the climatic classification for the municipality of Araguaína (TO), based on the methodological proposals of Köppen and Thornthwaite. In this case, a historical series referring to the years 1991 to 2020 was used. As a result, there is 1761.9 mm of accumulated annual precipitation and a Potential Evapotranspiration (ETP) in the order of 1425.36 mm; the average monthly temperature of the municipality over 29 years was 25.4 ºC. The Water Surplus (WSR) found was 638.19 mm, while the Water Deficit (WDE), represented by the months of May, June, July, August, September and October, was around 301.65 mm for the years analyzed. Regarding the climate of the municipality, according to the Köppen proposal, it is of the Aw type, tropical with a dry season in winter; for Thornthwaite, the climate is classified as B2 - w- A’- a’, therefore, humid, with Moderate Deficiency in Winter, Megathermal with climatic subtype a’.
