THE ANALYSIS OF THE ENHANCED-V STRUCTURES ATOP TORNADIC STORMS ACROSS ROMANIA

Calin NUCUTA

ABSTRACT: Enhanced-V is a structure that appears at the top of a storm and it is often associated with severe weather, especially hail and tornadoes (McCann 1983, Adler et al., 1985). These structures can be observed through satellite images provided by satellites such as Meteosat Second Generation, due to the spectral, time and space resolution the satellite has. The objective of this article is to determine the details of the enhanced-V type structures that have appeared in the upper structure of tornadic storms across Romania. All the cases of tornadoes that have been reported in Romania have been selected from the European Severe Weather Database (ESWD) and for each case a series of analysis were made to determine first if such structures were present and secondly, to find specific parameters of these structures. Analyzing the most clearly defined type of enhanced-V structures was the last step in determining which the best defined enhance-V structure was.
