Abstract

The paper presents a description of the course of ice phenomena in three rivers (Rega, Parsęta, Łupawa) in the coastal zone (Southern Baltic) in the territory of Poland. An evident acceleration of the term of decline of ice phenomena has been observed over the period of the last 60 years, varying from 3 to 5 days∙dec-1. The situation caused shortening of the ice season in a range from 3 to 7 days dec-1. The observed transformation of the ice regime of rivers should be associated with climatic changes. The analysis of air temperature in the same period for two meteorological stations (Kołobrzeg, Łeba) suggests a considerable increase in the mean annual air temperature, amounting to 0.3 and 0.2ºC∙dec-1, respectively. In the monthly distribution, temperature growth was the highest in April, where an increase in air temperature of 0.5ºC∙dec-1 and 0.4ºC∙dec-1 was recorded, respectively.


Key words: ice phenomena, river, coastal, Baltic
