Abstract

The present work had as objective to analyze the rainfall and preliminarily estimate the climatologic water balance of Fernandes Pinheiro city, Paraná. The series of the studied data comprehended the period from 1963 to 2004, of the Agrometereological Center of Fernandes Pinheiro, monitored by the Agronomic Institute of Paraná (IAPAR). The methodological procedures are guided by statistical calculation of the average, the standard deviation, the annual and monthly coefficient of variation, and the method of the climatologic water balance. The obtained results indicated that, independenton the rainfall amount, the presence of a water deficit on the soil is natural, and in despite of the little quantity of the annual rainfall variability, there is significant monthly rainfall variability in Fernandes Pinheiro.
