CLIMATE SIGNALS OF THE NORTH ATLANTIC OSCILLATION DETECTED IN THE CARPATHIAN BASIN
Abstract. North Atlantic Oscillation (NAO) can be considered as the primary large scale atmospheric driver of the European climate, especially in winter. In the present paper, first, NAO effects on regional circulation represented by the circulation patterns (CP) using the Hess-Brezowsky Grosswetter...
