The relationship of parameters of ice conditions in the Pomeranian Gulf with the atmospheric circulation types
Języki publikacji
Abstrakty
In the present paper there was applied a catalogue of circulations types according to J. Lityński as well as data concerning ice conditions, like the number of days with ice (L), length of ice season (S) and maximum thickness of ice (H) for Świnoujście-sea and Kołobrzeg-sea for winters within 1950/51 - 1989/90. For one month's and several months winter periods the selected circulation types were correlated to the accepted parameters of ice conditions. Equations of linear regression as well as polynomial of the second degree were applied. The statistical significance of relationships was determined with the aid of Fisher-Snedecor's (F) significance test. There was found, that on the number of days with ice (L), length of ice season (S) and maximum height of ice (H) affect mostly the anticyclonic and zero circulation types of eastern component (NE a,o + E a,o), as well as cyclonic and zero circulation types of western component (SW c,o + W c,o + NW c,o). The highest values of correlation coefficient for these directions were obtained in the period from December to February, while relatively high also for December only, what points some prognostic value. For earlier months, in principle, no significant relationships were found. More significant relationship occurred in the of Świnoujście when compared to Kołobrzeg, the highest for maximum thickness of ice (H) and the number of days with ice (L).
