摘要

Tornadoes and waterspouts occur in various parts of Greece and the research of recent years has shown that they are not as rare as previously considered. Research and systematic recording began in Greece in 2000 and carried out systematically in the last 15 years. Based on these 15-year data, tornadoes and waterspouts or tornado funnel clouds occur at about 50 days a year, on average. Analysis of the geographical distribution showed that tornadoes appear almost in all areas, but with a greater frequency over the Ionian Islands, the coastal areas of Western Greece, the low elevation areas of Macedonia and Thessaly and the sea areas north of Crete. Regarding the strong and most destructive tornadoes i.e. those with an F2 intensity or greater of the scale Fujita, they occur on a yearly average of six days, in various areas of the country. Tornado outbreaks can also occur in both tornado number and successive days of activity that are related to extended damage. The aim of this paper is to examine the occurrence of tornadoes/waterspouts in Greece during the period of 15 years from 2000 to 2014 (spatial and temporal distribution) and to investigate some climatological characteristics including the likelihood of occurrence by regional unity. Also, a comparison of the above data with the boundaries of the three IEC classes and the under development windfarm areas is undertaken. Useful conclusions about the risks of a windfarm and potential harmful consequences due to the tornado/waterspout occurrence are drawn. They can cause significant damage, from blades breakage up to tower buckling and their total destruction and fall, depending on the class and the tornado intensity level.
