Description :
This article has presented the analysis results of the changes in the sea surface temperature (SST) in the Baltic Sea observed in 2°x2° grid with its centre co-ordinates 55°N and 19°E (mean monthly values, data source COADS ; Slutz et al. 1985, Woodruff et al. 1987). This sea area covers the Bay of Gdańsk and the area of South-East Baltic (Gdańsk Deep and S part of Gotland Deep) adjacent to it in the north. The analysis of correlation between the SST and the temperature of air made use of a series of monthly air temperatures measured at the stations in Stockholm and Gdańsk-Wrzeszcz (Mietus, 1998). This analysis indicates that the increase in the SST in the said sea area in the 20th century may be estimated around the values of 0.6 - 1.2°C (+0.9 (+-0.3)°C). The greatest increase in the SST occurs in the months in which the influence of radiation factor on the thermal balance of this area is not very significant. The influence of the circulation factor may be accountable for the changes in the SST. The increase in the frequency and intensity of advection of the Atlantic air during the winter period results in clearly milder winters in the regions of Polish coasts on the Baltic Sea (Marsz, Styszyńska, 2001). - (BJ)
