Opis:: This paper evaluates the accuracy of estimates of the Standardized Precipitation Index (SPI) using gamma, normal and log-normal distributions. In order to classify the above methods, the authors performed an analysis of the quality of theoretical distributions to empirical distribution, obtained on the basis of monthly precipitation sums during the vegetation season in a multi-year period 1954–1995 in Łódź.

Opis:: The standardized precipitation index (SPI), standardized reference evapotranspiration index (SEI) and standardized climatic water balance index (SCWBI) were used to analyze moisture conditions in the vegetation seasons of 1954–1995 in Łódź. SPI and SEI were calculated on the assumption that empirical monthly precipitation sums and monthly sums of reference evapotraspiration are gamma distributed. Because monthly sums of climatic water balance are normally distributed, they required standardization to SCWBI. The aim of study was to compare those three indexes (SPI SEI and SCWBI) for years 1954–1995 in Łódź.
