Synoptic Climatological Comparison of Hazardous Weather Phenomenons at Hungarian Airports

Abstract

Weather plays a role approximately in every fifth airplane accident or incident. In order to be able to estimate how vulnerable the weather is to the safe execution of the flights, it is necessary to examine climatologically the specificities of the different geographically located airports. The occurrence of dangerous weather elements were investigated at the Hungarian airports. Halfhourly METAR telegrams were evaluated. The dangerous weather phenomena were defined. The coexistence of each weather element as well as its seasonal frequency was investigated. To be able to interpret the dangerous weather factors involved, a scoring method was introduced. Scoring also takes into account the degree of danger of the phenomenon. In case of joint occurrence, hazard scores are added. The synoptic climatological data published in the thesis can serve as a basis for the development of a weather risk assessment method.
