CLIMATE CLASSIFICATION AND CLIMATIC WATER BALANCE IN MATO GROSSO STATE, BRAZIL

This paper proposes the climatic water balance and climatic classification for 13 conventional meteorological stations (CMS's, from National Institute of Meteorology (INMET) networks, located in Mato Grosso State (MT) and in the state division between MT and Goias State (GO). The evaluated stations are named: Caceres, Canarana, Diamantino, Gleba Celeste, Matupa, Nova Xavantina, Padre Ricardo Remetter, Poxoreo, Rondonopolis, Sao Jose do Rio Claro, Sao Vicente, and the Aragarcas station (GO). The annual temperature average ranged between 23.00 and 26.84 degrees C for Cuiaba and Sao Vicente, respectively. The total annual precipitation ranging from approximately 1200 to 2000 mm in the evaluated seasons, with higher levels in the North and Central North and in the regions with altitudes close to 800m. By Koppen climate classification, the 13 stations have only two climatic types: Aw (other stations) and Cwa (Sao Vicente). By Thornthwaite classification occurred greater climatic variability, however, the predominant features of megathermic climatic with concentrations of ETP in the summer less than 40%. Observe the influence of latitude and altitude on weather patterns of Mato Grosso State.
