Climatic regionalization of Croatia according to W. Köppen for the standard period 1961 – 1990 in relation to the period 1931 – 1960

U članku ja dana klimatska regionalizacija Hrvatske po Köppenu za razdoblje 1961. – 1990. god. i uspoređena s regionalizacijom iz prethodnog standardnog razdoblja. Izračunati su potrebni vertikalni gradijenti temperature i padalina. Pokazalo se da je broj klimatskih tipova u najnovijem razdoblju smanjen, a njihove su granice promijenjene. Izrazita je promjena granice sredozemne klime s vrućim ljetom, koja obuhvaća samo otočni i uži obalni pojas Dalmacije, a podalje od obale prelazi u umjereno toplo vlažnu klimu. Razgraničenje Cs i Cf klime potkrijepljeno je i Walterovim klimadijagramima Pule, Raba, Malog Lošinja i Zadra.In this paper climatic regionalization of Croatia after W. Köppen for the standard period 1961 – 1990 is presented. The resultats are compared with the climatic map from previous standard period 1931 – 1960. For this purpose the vertical air temperature gradients and vertical precipitation gradients are calculated. In the last standard period the number of climatic types is reduced and the climatic boundaries have been changed. This is particularly related to the Mediterranean climate with hot summers (Csa). This type of climate comprises only the islands amd narrow belt along the Dalmatian coast. Further inland is the area of temperature warm humid climate with hot summers (Cfa). The exact boundary separation of the Cf/Cs climatic areas are demonstrated by Walter climatic diagrams (Pula, Rab, Mali Lošinj, Zadar)
