Russia usually gets very few tornados. This year, however has been very strange as there has been a rash of them, the latest in Novisibirsk. The US gets lots of them because we have large plains between the Gulf and Canada. Large amounts of hot moist air meets large areas of cold dry air, and the temperature and moisture differentials cause huge storms. Russia's hot areas are also very dry. You don't see the levels of heat and moisture differential that we have there. Anyway, even though I think Global Warming is a hoax, it is interesting to see a new weather pattern this year.
