COMPARATIVE ANALYSIS OF SEVERE STORMS, CONNECTED WITH EXTREME PRECIPITATION IN BULGARIA (1951-2010)
Published: 1 Jun 2014
Abstract: During the last years there is an evident upward tendency of damages caused by natural disasters. Much of them are caused by extreme events such as torrential precipitation associated with thunderstorms or/and wind storms and they tend to increase. A comparative analysis of some very extreme precipitation events was carried out using all the available data for torrential precipitation (totals over 100 mm/24 h) from the meteorological network of the National Institute of Meteorology and Hydrology for the period 1951–2010. The annual distribution of extreme precipitation events over different parts of Bulgaria is presented. For the territory of the country as whole an increase of the mean annual number of days with torrential precipitation was found recently. This increment was statistically significant in Eastern Bulgaria and Black sea coast where the number of flood rain events has increased especially during the pick of active tourist season.
