Abstract

Studies of climate changes in Brazil are scarce, mostly due to the lack of long-term, reliable weather data series. In many locations, outside the metropolitan regions, there are few meteorological stations with historical series covering over than 30 years, as in Viçosa (MG). This work aims to study the variation of maximum and minimum average temperatures, rainfall and relative humidity, in annual and monthly scales, during the period from 1968 2015, in Viçosa (MG), seeking evidences of climate change and increasing the climatology studies in a regional scale in Brazil. The trends were evaluated using the Mann-Kendall test and the causality of the inverse correlations with the Covariance Analysis (ANCOVA). Among the results, it was verified the progressive elevation of the maximum temperatures in the spring, summer and autumn, as well as the minimum temperatures in practically all the months of the year. The winter has been characterized as increasingly dry and prolonged, occurring an increase of temperatures in the transition to the hydrological summer (month of October).
