CHARACTERISTICS OF ANNUAL AIR TEMPERATURE, THERMAL SEASONS AND THE VEGETATION SEASONS IN DZIWNÓW
The chief aim of the research was to identify temporal variability of mean annual air temperature and the occurence of thermal seasons and the vegetation season in the Pomeranian Bay coastal zone, for example Dziwnów. Thermal seasons were determined on the methodology used by Wiszniewski (1960), Makowiec (1983), Piotrowicz (2000), which includes eight seasons and is the right of the phenological properties (SzygaPluta, 2011). In addition, the vegetation season was characterized by the occurence, in accordance with the Merecki’s criteria (1914). Thermal properties analysis for the study area was made on the average daily air temperature data from the 1956–2009 period. The paper presents the long-term trends of temperature variability of the Pomeranian Bay coastal zone.
