THE CHANGES IN THE DURATION OF THE METEOROLOGICAL VEGETATION PERIOD IN POLAND IN THE YEARS 1971–2000 AND 1981–2010

Abstract

In this paper, changes in the duration of the meteorological vegetation period in Poland were analyzed for the three decade period: 1981–2010 as compared to the 1971–2000 period. The meteorological data regarding the monthly mean air temperature values from 53 weather stations distributed evenly across Poland were used. It was proved that the meteorological vegetation period in the years 1981–2010 increased by four days on average, as compared to the 1971–2000 period.
