Abstract The aim of this study is to characterize pluvial conditions in the Wielkopolskie Voivodeship at the turn of the 20th and 21st centuries. The work comprises analysis of the long-term, annual and seasonal precipitation, as well as their spatial distribution and variability concerning the number of days with precipitation of a certain intensity in the period of 1981–2014. The study was based upon daily sums of atmospheric precipitation in years 1981–2014 derived from 5 synoptic stations, 9 climatological stations and 78 precipitation stations located in the Wielkopolskie Voivodeship (Fig. 1). The data was obtained from IMGW-PIB. The Wielkopolskie Voivodeship is an area with relatively low precipitation sums comparing to other regions of Poland. In the years 1981–2014, the average annual rainfall amounted to 548 mm and was characterized by high variability of rainfall amounts from year to year (Fig. 2, 3). The amplitude of fluctuations exceeded 500 mm. In the examined period, the average annual rainfall (from 92 stations) presents an upward trend (23 mm/10 years), the highest in the summer. The number of days with precipitation is increasing at a slower rate (Fig. 4). The distribution of rainfall in analyzed area is characterized by considerable spatial diversity (Fig. 5, 6, 7). The highest average sum of precipitation and the highest number of precipitation days were registered in the north-west, northern and southern parts of the region. On the contrary, the driest was the Wrzesińska Plain and the eastern part of the Wielkopolskie Voivodeship. Majority of the region is characterized by an average of 120–160 days with precipitation per year. The lowest number of such days are noted in the north-eastern part, and the highest – in the north-western part of the voivodeship (Fig. 8). In the seasonal distribution of rainfall, a clear prevalence of summer precipitation is visible, comprising 36.6% of the annual sum, with a maximum in July of 76.5 mm on average. The most intense precipitation, i.e. above 20 mm day, was least frequent in the central part of the study area (Fig. 9). The most diverse distribution is characterized by the weakest precipitation, i.e. less than 1 mm per day. Considerable variation in spatial distribution of precipitation indicates that rainfall is often of local nature. The amount and duration of precipitation as well as range depends on the cloud structure formed under specific synoptic conditions and local relief. The concentration of stations considered in a given area provides a more detailed image concerning the actual spatial variation of precipitation.

Abstract
The work detailed in this article aimed to determining the multi-annual and spatial variability characterising start and end dates of growing seasons in Poland, as well as their durations. The study used data concerning monthly air temperature from the period 1971-2010, which were obtained from the Institute of Meteorology and Water Management - National Research Institute (IMGW-PIB). A growing season was defined as a period of mean daily air temperature 5°C. To determine the start and end dates of the above-mentioned period, use was made of the mathematical formulae proposed by R. Gumiński (1948). Over the analysed multiannual period, first days of growing seasons were seen to occur ever earlier, while last days have been occurring later and later. The most marked changes of start date were found to characterise Łeba (4.7 days/10 years) and Suwałki (4 days/10 years). However, at 5 of the 15 stations, the changes noted achieved statistical signifi cance. The most considerable postponements of the end of the growing season were in turn those found for Łeba (3.8 days/10 years) and Rzeszów (3.6 days/10 years). At as many as 8 of the 15 stations, the prolongations proved to be significant statistically. Average durations of growing seasons varied across the range from 200 days in Suwałki to 237 days in Wrocław. However, at most (11 out of 15) of the stations, there was a statistically significant increase in the duration of the growing season (of from 3.9 to 8.5 days). However, the change was seen to be more due to prolongation at the end of the growing season than to a changed start date.
