Digital Maps of the Selected Climatic Parameters with Emphasis on the Primorsko-goranska County

In Croatia only in Primorsko-goranska county and neighbouring Ličko-senjska county one can find such a variety of geographic, orographic and hence also a climatic characteristics. Climatic characteristics of the period 1961-1990 have been presented through the maps of mean annual values of the three climatological parameters: air temperature, precipitation amount and relative humidity that have been until now produced in DHMZ1. Mean annual sum of global solar radiation has been presented for the 1961-1980 period according to the available measurements. The maps cover the Croatian territory but the emphasis has been laid on the Primorsko-goranska county. Digital maps of climatological fields have been produced in GIS2 software Ilwis. Geostatistical methods, namely Multiple Linear Regression (MLR) and Kriging have been applied to estimate climatological fields on a regular grid. The lowest values of the global solar radiation and temperature one can find on the tops of the Gorski kotar mountains (1.1 MWhm-2 and 2°C) and the highest on the islands (1.5 MWhm-2 and 16°C). Relative humidity and precipitation amount are the highest on the mountain tops (>85% and >3000 mm) and the lowest on the islands (65% and 1000-1250 mm).
