Bioclimatic conditions of the Lubuskie Voivodeship

Abstract

The objective of the present work is to present the temporal and spatial characteristics of the bioclimatic conditions of the Lubuskie Voivodeship. The daily timed values (12UTC) of meteorological elements in the period 1971-2006 from three stations (Subice, Gorzw Wielkopolski and Zielona Gra) were used as the basis for the calculations. In order to assess the bioclimatic conditions, a thermal stress index UTCI (Universal Thermal Climate Index) that is calculated with the use of BioKlima 2.6 software was applied. The analysis shows that thermal stress related to 'slight and moderate cold stress' and 'no thermal stress' is a dominant factor (80%) affecting the bioclimatic conditions of the Lubuskie Voivodeship. During the analysed period, days with thermal stress related to cold stress occurred more frequently than those with thermal stress related to heat stress. On the basis of a linear regression trend, a positive trend for thermoneutral conditions days and heat related stress days (UTCI>32 C), as well as a negative trend for cold related stress (UTCI<-13), were ascertained.
