Anti-Hail Protection-Assessment of Financial Effects on the Territory of Belgrade

The aim of this work is to assess damage to the City of Belgrade caused by the unfavorable weather condition of hail due to the absence of anti-hail defense of the city, and to argumentatively point out the necessity of introducing new technical-technological systems for preventing the effects of adverse weather conditions. The results are based on the direct correlation-analyses of two real unfavorable weather events and the estimated financial damage caused by these events. The overall calculation also takes into account financial investments (new financial model) necessary to establish two essentially different systems for anti-hail protection. The damage caused by the hail on the territory of the City of Belgrade and the financial investment in anti-hail protection to reduce it are empirically established for the first time. It is shown how the damage could be transformed to profit, as the financial investment in anti-hail protection is lower than the damage that hail can cause

Extreme floods in Serbia occurring simultaneously with the high water levels and heavy rains : case study

This paper discusses possible development or so-called scenario of extreme floods in the Republic of Serbia that would be caused by simultaneous occurrence of high-water levels/discharges on the rivers and heavy rains. As illustration, two scenarios are presented based on independently recorded cases of high water levels and heavy rains of May 2014. A scenario of the floods caused by the interaction of reached high water levels and observed heavy rains is particularly examined. Research of the floods is proposed with the parameters of flood waters that would not have highly unexpected values, but would be more extreme than all the past ones. Scenarios would yield new potentially useful information on the influence of floods on human communities. Proposals are presented for more efficient controlling and regulating of floods in the Republic of Serbia

The occurrence of a tornado in Serbia on 31 march 2013

Tornado occurs very rarely in the territory of Serbia. The occurrence of a tornado above Torda (Vojvodina, Serbia) on 31 March 2013 indicted the importance of monitoring such a dangerous weather phenomenon, knowing its characteristics and forecasting it. This paper analyzes the synoptic conditions and vertical structure of the atmosphere that prevailed during the development of a supercell with a tornado. Changes in temperature and air pressure are presented on mesoscale maps. The analysis was performed by using the Nonhydrostatic Mesoscale Model (NMM). The tornado occurrence was monitored via satellite images and radar characteristics of a supercell. The cause of tornadogenesis has been ascertained. According to the EF scale, the tornado reached F0 intensity. Damages to roofs, power lines, trees and cars caused by the wind (>35ms-1) are also presented
