Abstrakt

This article presents the variability and a changeability of the ice phenomena on the Słupia River based on the data recorded in the water gauge station in Słupsk during the period from 1960 to 2013. The work aims to characterize and analyze the ice phenomena and risks associated with them occurred in the climate changes on the southern Baltic Seashore zone. This work presents and describes the time when the ice phenomena appeared (the date when the river froze), the duration of the ice covers the river and the date of thaw. There is shown and described the structure and form of the ice cover which appeared during the various phases as the phase of freezing, ice duration and the phase of taw on the river. The thickness of the ice cap and its variability in time was analyzed too. In the analyzed period the longest time of occurrence the ice phenomena was in 1963 and there were 79 days. The shortest time was in 1999 and there were only 2 days. The earliest appearance of the ice phenomena was on the 1st of December in 1994 and the latest date was on the 15th of Marc 1962.
