ABSTRACT



The research has been aimed at studying both seasonal and annual changes in air temperature and precipitation over the past 40 years, i.e. from 1961 till 2000, as well as in 2001-2003 period. Additionally increase/decrease rates for all the parameters under analysis were to be determined, as well as thermal and precipitation rating of months over the studied period. The research was based on data recorded over respective 1961-2003 decades and months for air temperature and precipitation that were collected at Lipki agro- and weather station, near Stargard Szczeciski. Magnitude of the standard deviation (S) from the standard from 1961 to 2000 was applied as a criteria for thermal rating all the months over the studied period. To evaluate deficiency or excess of precipitation in particular months a criteria of percentage of total monthly precipitation over the standard value (75 - 125%) was applied.

Monthly, seasonal and annual changes for both air temperature and precipitation tend to be linear. Over the studied period for all the moths, excluding November, a rising tendency for air temperature was observed. A statistically significant, positive trend was observed for April, May, July and August. The biggest increase for temperature, on average by 0.8°C/10 years, was found for January. No clear, solid trends have been detected for precipitation. At the beginning of a year a rising tendency was noticed, while towards the month end precipitation tend to drop. Still, only in May the trend was statistically significant and found negative.

The year 2003, whose summer season was found exceptionally hot and very dry, was also evaluated in terms of temperature and precipitation.

Key words: air temperature, precipitation, variability, Szczecińska Lowland.
