Boundary separation of Köppen\u27s climatic types Cf and Cs in Croatia

Granica Köppenovih klimatskih tipova Cs (sredozemnih klima) i Cf (umjereno toplih vlažnih klima) u Hrvatskoj prolazi krškim područjem. Krš nije homogen, ali je najvećim dijelom propustan. Zato jedan dio padalina nije iskoristiv za biljni pokrov. Efektivne su padaline manje od izmjerenih. Uzimajući u obzir efektivne padaline, granica Cs i Cf klime prodire znatno sjevernije nego što proizlazi iz izmjerenih padalina. Stoga Cs klima obuhvaća široki pojas uz zapadnu i istočnu obalu Istre, veći dio Kvarnerskog primorja, te Ravne kotare.The boundary of Köppen\u27s climatic types Cs (the Mediterranean climates) and Cf (the temperate warm humid climates) is entirely on Karst terrain. Karst is not homogenous but the greatest part is permeable. This is the reason that a certain part of rain in summer months is not available to vegetation cover. Effective precipitation is smaller than the rain measured by rain-gauge. In this way, taking solely the effective July rainfall into account, the boundary between Cf and Cs climatic types penetrates much more to the North than according to the rainfall measured by rain-gauge. In this way the Cs type of climate tretches parallely along the western and eastern coast of Istria Peninsula, in the grater part of Quarner Island and Ravni kotari
