abstract:
The paper is based on data obtained from the Institute of Meteorology and Water Management in Warsaw, concerning effective temperature (TE) and degree of cloudiness by low- (CL) and intermediate-altitude clouds (CM) (disregarding the high-altitude clouds). The data had been collected at 13 meteorological stations in 1971-2000 at 12:00 hours UTC. The effective temperature (TE) necessary to determine the temperature of effective radiation was calculated from the Missenard formula. Evaluation of temperature perception was based on the scale of thermal percep-tion proposed by Baranowska. The scale consists of 7 thermal perception grades: very hot, hot, warm, comfortable, cool, cold, and very cold. Bioclimatic conditions of North-Eastern Poland were evaluated from mean monthly and mean seasonal temperatures of effective radiation and their vari-ability in 1971-2000. Frequency of grouped thermal perceptions was determined: favourable percep-tions were those graded from cool to comfortable to warm; unfavourable perceptions were those graded cold and very cold (cold discomfort) as well as hot and very hot (hot discomfort). The Northern Podlasie Lowland and the eastern part of the Masurian Lake District show a particularly high stimulation potential due to the occurrence of extreme thermal perceptions; the most favourable biothermal conditions prevail in the western part of the region studied. Of all the periods analysed, the highest spatial variability of perceived climate occurs in the cold half-year, particularly in win-ter. The highest number of days with the biothermal optimum occurs in autumn and spring i.e. from 64 to 76, and from 56 to 64 respectively, increasing from east to west.
