The paper presents the results of analysis of duration of precipitation sequences and the amounts of precipitation in in-dividual sequences in Legnica. The study was aimed at an analysis of potential trends and regularities in atmospheric pre-cipitations over the period of 1966–2015. On their basis a prediction attempt was made for trends in subsequent years. The analysis was made by fitting data to suitable distributions – the Weibull distribution for diurnal sums in sequences and the Pascal distribution for sequence durations, and then by analysing the variation of the particular indices such the mean value,variance and quartiles. The analysis was performed for five six-week periods in a year, from spring to late autumn, ana-lysed in consecutive five-year periods. The trends of the analysed indices, observed over the fifty-year period, are not sta-tistically significant, which indicates stability of precipitation conditions over the last half-century.
The results of a long-term water level monitoring in three forest ponds are presented in the paper. The ponds are locat-ed in the Wielisławice and Laski forest districts in South Wielkopolska, Poland. Two of the analysed ponds are natural ones supplied by precipitation and the third now is disused artificial fishpond of throughflow water management. Systematic water level measurements, as well as measurement of basic meteorological conditions – precipitation and air temperature – were carried out in the 2000–2016 hydrological period. The basic statistics as well as the trends in long-time changes in water levels, were determined using the nonparametric Mann–Kendall test were calculated. The results obtained were sta-tistically inconclusive, but they indicated downward trends in water levels in the natural ponds and upward trends in water levels in the artificial pond. Although a statistically significant downward trend was observed in only one natural pond, it may suggest some negative changes occurring in the catchment of ponds in general.
