Storms continue, after the election – silence

Thunderstorms will continue until the day of elections, said BTA Deputy Director-General of the National Institute of Meteorology and Hydrology Bulgarian Academy of Sciences Prof. Dr. Petyo Simeonov.

Simeonov said that in recent years, a trend of increase of days with lightning activity. In his words would probably have increased the territory of thunderstorms.
Because of global warming like storms more often we rush through the cooler months in April and by September and scientists are as usual months – May and June. Thunderstorms appear already in the winter and in February – for example, hail tip is customary for the summer season, said a scientist.
Lightning increasingly fall and unusual places such as coastal zone in eastern Bulgaria. Change in the characteristics of the thunderstorms observed by scientists in 1991, since when has the new 30-year period of observation of these processes. These changes require updating of basic information on legislation regulating the country malniezashtitata said Simeonov. Should government authorities responsible for preparing an update of an existing 2005 malniezashtita ordinance for buildings, outdoor facilities and open spaces. It is expected to include new scientific estimates of changes in the system of thunderstorms. At this stage, the phenomenon observed of 135 meteorological stations of the institute, located throughout the country, some of which are from before 1900. Stations supported by the scarce budgetary resources of the institute and its own revenues, Simeonov said.
About 260 professionals, among other weather phenomena reported visual thunder strike and watch as their duration data recorded in special journals. Data Thunderstorms restricted area shall be collected through radiolocation system. Two methods are not sufficient for the preparation of accurate estimates svrahkratkosrochni in an hour-hour and a half and projection of the region, which will fall lightning, Simeonov told. The reason is that our country is among the few European countries which do not have a system for registration of lightning. Such equipment costs about 800 000 leva and is produced in Germany, Finland, USA and others. The purchase does not get funds from the budget of the institute. System is necessary to enable the tool to measure the intensity and frequency of wildfire activity, and not as now – of the eye.
Lightning hit Bulgaria for a station on an average 25 hours per year. 5 flashes per sq. / km fall in the country. Most storms with lightning have in Vratsa – in 108 hours a year. Chirpan follow, and Sevlievo Smolyan. Bulgaria has an average of 29 days on station by lightning, said the expert.
