Abstract. Two severe wind storms happened in November 1964 and December 2012 in the highest regions of the central part of the mountain Stara planina - the Central Balkan. They caused heavy damages to the technical equipment and the buildings along the ridge of the mountain - in 1964 the roof of the main TV building was blown away by strong north winds and the TV tower itself was broken. The whole area of the damages spreads over 30 km. In 2012 a Mediterranean cyclon hit the same regions with powerful south winds and a smaller radio tower collapsed due to the heavy wind and ice load. The purpose of this study was to evaluate the meteorological conditions during these events with focus on the wind and ice severity. We have analyzed the synoptic condition at different pressure levels in order to estimate the main dynamic of the atmosphere over the Balkan Peninsula and we have used WindNinja version 3.8.1 for simulation of the surface wind field in a smaller region. Finally, using simple icing model we have estimated also the possible ice load. WindNinja is a numeric aerodinamicall diagnostic model developed for analysis of forest fire behavior. It is developed by the Missoula Fire Sciences Laboratory, Forest Service U. S. Departmen of Agriculture. In this research a daily meteorological data from Botev peak and station Mazalat has been used during the time of the respective extreme event (November 1964 and December 2012).
