abstract:
The results of 24 hour measurements of atmospheric precipitation and soil temperature at the depth of 5 cm carried out in 10 meteorological stations in the period from December to March in the years 1961-2000 were the basis of the presented analysis. The frequency and the amount of precipitation during the periods of soil thaws, but also during the periods of above zero temperature just before freezing of the soil, by days and 10-day periods (decades), were characterized. At least 2 day periods of an average above freezing 24 hour soil temperature at the depth of 5 cm, but occurring after the first at least 3 day period with an average 24 hour temperature below 0oC constituted the soil thaw. It was observed that the thermal conditions of the soil in Pomerania constitute large potential possibilities for the retention of precipitation water in soil during the whole period of winter, even in January and February.
