Comparison of PET and UTCI values for three months of year 2018 in Zagreb and Split

Biometeorological conditions in Croatia are analysed in Croatian Meteorological and Hydrological service every month, upon the values of biometeorological index physiologically equivalent temperature (PET). The results are published monthly in Meteorological and Hydrological Bulletin, together with the results of the monthly weather analysis from the other aspects. UTCI parameter is not yet operationally in use in Croatia. The intention was to compare PET values with analogous UTCI values, for three terms daily (7 a.m, 2 p.m. and 9 p.m.) over February, March and April 2018, for Zagreb in the mainland with continental climate, and for Split at the seaside with maritime climate. In almost whole Croatia average air temperature deviations of three months in 2018 from the corresponding multiannual averages 1961-1990 were in the following categories: cold in February, normal in March and extremely warm in April. For each daily term presented is thermal sensation according to PET and UTCI values, using the same values of PET and UTCI parameter as limits between categories of thermal sensation. Presented are also PET categories for average decadal PET values, as well as UTCI categories for average decadal UTCI values for each of three months 2018. In order to estimate the deviations of thermal sensation from the normal values in the referent climate period 1961-1990, determined are also decadal deviations of PET and UTCI values 2018 from average PET and UTCI values in 1961-1990 period for each of three terms.
