CLIMATIC HAZARDS IN THE WARM PERIOD IN DOBROGEA

M. Lungu

 

                ABSTRACT.  - Climatic hazards in the warm period in Dobrogea. Climatic hazards occurring in the warm period all over Dobrogea have in common the positive temperatures. The different warming degree, either having a radiative nature , or with the penetration of warm tropical air (continental or maritime) is the main cause for genesis/occurrence and territorial climatic hazards differences in the warm period.Therefore, the abundant rain, the hail storm, etc depend on the intensity of the thermal convection. The contribution of the warm tropical air, to the amount of continental air masses leads to massive warming; these, combined with the thermal convection, against the background of a predominantly anti-cyclonic weather, generates episodical droughts (in spring, summer, autumn). I have to mention that there are also cases when dryness phenomena and drought happen  regardless of the thermal summer or winter conditions. Therefore, in the warm period of the year, I have identified in Dobrogea the following climatic hazards: hail, pouring rainfall, massive warming, to which are added tornadoes and waterspouts.

 

                Key words: climatic hazard, hail, pouring rainfall, tornado, waterspout, massive warming.
