Szukana fraza: [Abstrakt = "The analysis concerned the variability of daily precipitation totals observed during the second half of the 20th century at five stations in Poland. The elements examined were number of days with precipitation exceeding given thresholds, lengths of wet and dry spells and precipitation amounts in a single spell. There is an upward trend for the number of spells and days with precipitation, and a downward trend for mean precipitation during a given spell. Changes in peak precipitation are not uniform, there being negative trends at some stations and positive ones at others. However the lack of a trend for precipitation totals combines with the climatic warming now to be observed to imply risk of a water deficit."]
