ABSTRACT
This study presents three new regionalizations based on materials from 1971-2000 and from 1981-2010, and for an assumed scenario of a temperature increase of 1ºC. Heat resources are expressed in these regionalizations as sums of effective temperatures ≥10ºC, and water resources such as Sielianinov’s hydrothermal coefficient K from June to August. An increase was found in the area of the moderately warm region with a sum of temperatures ≥10ºC from 61% in 1931-1960 to 62% in 1971-2000, 87% in the 30-year period 1981-2010, and 73% for the scenario with the assumed 1ºC temperature increase. In the last case, a new thermal region appeared: a warm region with a sum of temperatures ≥10ºC in the range of 2800-3200ºC, covering almost the entire remaining area of the country. As warming progresses, in the absence of clear tendencies for atmospheric precipitation, the climate in Poland is becoming increasingly dry. Areas classified as dry with a hydrothermal coefficient of 1.0-1.3 increased from 13% of the area of the country in 1931-1960 to 20% in the 30-year period 1971-2000, 46% in the 30-year period 1981-2010, and 65% for the scenario with a 1ºC temperature increase.
