Temporal and spatial variability of air temperature and precipitation at the Polish coastal zone of the southern Baltic SeaAbstract
The study concerns the analysis of temporal and spatial variability of thermal and precipitation conditions at the Polish Baltic coastal zone in the second half of the twentieth century and the first decade of the twenty–first century. The paper also presents its annual and daily extreme values of air temperature and precipitation. The study area includes the Polish coast of the Baltic Sea at which long–term measurements and observations of weather conditions have been performed within the national meteorological services at seven Baltic coastal stations. Their daily data of air temperature and precipitation taken from the measuring period of 1966–2009 were used in the study. For each meteorological station was set thresholds of annual average air temperature and annual total precipitation. Temporal variability of air temperature was determined by the thermal classification made by Lorenc (1998). Temporal variability of precipitation was determined by the precipitation classification made by Kaczorowska (1998).
