The study of time and climate is of extreme importance for environmental science, since it configures temperature, precipitation, to humidity and winds, and can impose limits on the environments in which organisms live. Being one of the driest regions of the country, the Brazilian northeast is characterized by large irregularities, which are caused by atmospheric systems and physiographic factors. Therefore, the present study aims to evaluate the precipitation variability of the Campina Grande microregion, through the monthly and annual space-time analysis of precipitation; And to identify the dry and rainy cycles of the studied area, with the aid of the rainfall anomaly index (IAC). For this, the rainfall data used in the research correspond to the monthly series of precipitation in the period 1994 to 2014 provided by the AESA for the temporal space evaluation of precipitation and for the calculation of the IAC. Where, the two extremely humid years were 2000 and 2011 and the extremely dry years were 1998 and 2012. The microregion has two distinct periods, one wet and one dry, with six months each.
Keywords: rain Anomaly index (IAC), dry period, Rainfall, northeast, climate.
