Mountain influence on the areal characteristics of types of convective precipitation

Abstract

The unique detailed precipitation data from a dense network operated in Serbia during the project of hail suppression have been used to define the relationship between a convective storm and associated precipitation. The data analysed were from 1982-1986 and from 120 firing stations in mountainous terrain and 115 in flat areas. The firing stations are those manned 24 hours a day by cooperative observers. The average distance between sites is 5 km. Detailed maps of the frequency of different precipitation types at all points of the network are plotted. A comparison is made between the results obtained from both mountainous and flat land networks. It is shown that alternate changes of the local maxima and minima of rain and hail shower frequency exist for the air mass (Cb) clouds. The air mass tracks from a NW direction in the river valley where it is flanked by orography. © 1992 Springer-Verlag.
