Bodźcowość warunków biometeorologicznych we Wrocławiu (Stimulating qualities of biometeorological conditions in Wrocław)
Journal Title: Acta Geographica Lodziensia - Year 2016, Vol 104, Issue
Abstract
Stimulating qualities of biometeorological conditions of Wrocław were analyzed on the basis of the values of the Universal Thermal Climate Index (UTCI) of the years 2008–2014. UTCI values were calculated from 1-hour data with the use of components of solar radiation balance, measured in the Agro- and Hydrometeorological Observatory of Wrocław University of Environmental and Life Science. Annual and long-standing courses of UTCI and the occurrence frequency of UTCI levels corresponding to a specific stimulating condition (heat and cold stress) were analyzed. For the selected cold-wave and heat-wave, the courses of the main meteorological determinants of UTCI were compared. It was demonstrated that the biometeorological conditions of Wrocław suburbia are characterized by a considerable frequency of heat load deficit. It was remarked that the number of incidents of cold stress has increased in recent years. In in the areas of relatively small surface roughness, the reason can be attributed to the dynamics of the wind in more frequently occurring cyclonic circulation.
