Abstract

This article shows results of a research carried out for the semiarid of Pernambuco, Brazil using daily time series of temperature and precipitation over 40 years, with future scenarios of climate change for the period 2010-2050. To determine present and future climate change trends, water balance results and outputs of the regional atmospheric model ETA nestled in global scenario of climate model nested in two global climate models HadCM3 and BESM were used. The results showed increased trend in maximum temperature, reducing minimum temperatures, reduced average annual rainfall, indicating tendency to aridization in the region.
