Alterações microclimáticas na cidade de Petrolina associadas a mudanças na cobertura do solo.

Abstract

The growth of irrigated fruit trees in the municipality of Petrolina - PE, mainly grape and mango, under the national sign. It becomes worrisome how intense practices for agriculture, the removal of native cover per irrigated crop, and can have more impact on the climate of the microregion. This study was to verify testing in data historians of testing testing in the data-the-round testing of Mann-Kendall and Pettitt. They analyzed the series of tem- peratures of the mean, minimum and minimum temperature, precipitation, radiation, insolation, wind speed, relative leakage and evaporation, between 1975 and 2014. mm by the MK test and the two testicles as the maximum and minimum temperatures increased, and radiation decreased. Evaporation, evaporation, insolation and wind speed, the negative trend, is no longer statistically significant.
