Diurnal variation of precipitation frequency in the warm half of the year according to circulation types in Kraków, South Poland

Abstract

A 117 year series of hourly precipitation data from Krakow, South Poland and the Niedźwiedź classification of synoptic weather types were the basis of a detailed study of diurnal precipitation variation and atmospheric circulation types. The analysis of the relationship between precipitation and circulation types was restricted to the warm half of the year (May–October). During this period precipitation ispredominantly liquid. This paper discusses the role of theCarpathian orographic barrier in the development of the 24 hour precipitation pattern.
