Climatic changes on Szczecin Seashore and their impact on river flows

Abstract An analysis has been made of the variability of temperature and precipitation at stations at Szczecin, Świnoujście, Resko and Kołobrzeg, as well as a study of river flows in the Ina and Rega Rivers in Goleniów, Resko and Trzebiatów, for the years 1955–2014. Data was provided by IMGW-PIB. Correlation and regression methods have been used in this work. Studies have shown that the average annual, spring and summer air temperature on Szczecin Seashore is rising. Precipitation totals remain basically unchanged. They grow a little in July in Świnoujście and in March in Szczecin. No significant changes in river flows occurred in the course of the examined sixty-year period. Flows in the Ina River rose slightly in February and they diminished in the Rega River in October in Resko and in May in Trzebiatów. Long-term variability of river flows is more strongly affected by the variability of precipitation totals than by the variability of air temperature. The variability of flows correlates most strongly with the variability of precipitation totals in March, April and November, while the influence of the preceding month’s precipitation on river flows is evident in all the year.
