Temperature conditions of Brno City on the level of mesoclimate and microclimate

Warunki termiczne miasta Brna w skali mikro- i mezoklimatu

Summary: The urban climate causes intensive physical stress with negative impacts on health. Stations with automatic measurement regime lying in potentially comparable climatic conditions but significantly different environmental conditions were selected in order to analyze the heat waves incidence. The urban climate was represented by the Brno-Zabovresky and Mendel Square stations and the suburban climate by the Brno-Turany and Jundrov stations. The number of tropical days in individual years, the number of days in heat waves, the sum of effective temperatures in heat waves above 30°C, the number of heat waves and the maximum and averages duration of heat waves were analyzed. The influence of albedo, emissivity and temperature (ir)regulation of different surfaces were also evaluated. The detailed study of climatic conditions at the stations placed in the city centre, outside the city centre and in the periphery proved that the mean annual temperature varies from 10.4 to 11.1°C. The maximum annual temperature varies from 36.1 to 37.9°C. The number of summer days varies from 178 to 260. The number of tropical days varies from 42 to 103
