UTCI applications in practice (methodological questions)

UTCI, although it was developed with the participation of scientists from 22 countries, has shortcomings and people using face various obstacles. The difficulties include wide range issues: different availability meteorological data in individual through kind air temperature which should be properly used calculations, or need recalculation wind speed. However biggest subject concern algorithms for mean radiant (Mrt) models programs simplify calculations this complex index though introduce approximations and, as a result, many false results. paper presents also UTCI applications urban bioclimate studies bioclimatic mapping, climate-human health researches biometeorological forecasts were primary purpose creation, but tourism recreation even change analysis.
