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.

Opis:: The data used in this paper come from nine IMGW stations from central-eastern region of Poland and they were registered between the years 1971–2005. On the basis of daily precipitation sums analysis during vegetation season, the number of days with precipitation was determined in particular classes. In central-eastern Poland during vegetation season days with very little and little precipitation were noted most frequently. Very little precipitation occurred most frequently in April; little, moderate and moderately strong precipitation - in June, and strong precipitation - in July. Whereas very strong precipitation was noted most frequently in June and July. Days with very little and little precipitation were noted most frequently in northern and north-eastern part of the area examined. While the number of days with moderate, moderately strong and strong precipitation showed little spatial diversity. Very strong precipitation was noted the most frequently in the area of Legionowo and Ostroleka. The number of days with very little precipitation during vegetation season was decreasing in subsequent years of the study. Statistically significant negative directional coefficients of the trend were noted most frequently in April. The number of days with very strong precipitation was also decreasing significantly in most of the stations.

Tytuł:: The assessment of atmospheric drought during vegetation season (according to standardized precipitation index SPI) in central-eastern Poland

Opis:: The paper presents an assessment of atmospheric drought during vegetation season defined on the basis of standardized precipitation index (SPI). The data used in this paper come from nine IMWM stations from central-eastern region of Poland, and they were registered in 1971–2005. The frequency of occurrence of vegetation season’s months was determined in particular drought classes. Spatial distribution of SPI index values was shown in all of the vegetation season’s months on the area examined. The direction and significance of values changes tendency of the analyzed index during the vegetation season were also defined. It was noticed that extreme droughts appeared four times less frequently than the normal months. Very dry months were noted most frequently in September while moderately dry – in August. The analysis of the frequency of spatial distribution of particular drought classes showed that extreme dry and very dry months occurred most frequently in western part of the area examined, while the moderately dry months also in south-eastern part. On the basis of the linear trend analysis it can be said that the SPI index values were slightly decreasing year by year.
