The Contact of Large Area Pressure Fields and the Weather of Hungarian Airports

Abstract

The positions of the large area pressure systems fundamentally determine the weather of the Central European area. In hemispheric sizes the monthly mean values of NAO index define the direction of the evolving flows. We treated the indices of nine years monthly NAO and the half-hourly measurements of four Hungary airports (METAR). In our work, we compared the values of NAO index with the monthly number of longest foggy half an hours in hungarian airports, and we also examined the contact between NAO index's course and the monthly longest period of precipitation days annually. We found relations in all two cases. Insofar as we would be able to write down more similar contacts, then we could make conclusions from the NAO indices forecast by climatological models to the climate change effects onto airports.
