    according to the BBCweather news site http://news.bbc.co.uk/weather/hi/news/newsid_8546000/8546373.stm

    For the first time in more than 60 years, the United States has had a month without a single tornado.

    During February the US would expect to see an average of 22 tornadoes hitting the ground. Despite 2010 being an El Nino year, which raises the risk of tornadoes forming, none were seen.

    Tornadoes form in the US when cold air over the northwest collides with warm tropical air coming in from the southeast and Gulf of Mexico.

    Normally the two air masses run into each other over the Great Plains of the Midwest, which provides the perfect environment for the monster storms to amass, but this year the jet stream has buckled unusually south over Texas and the southern states, bringing with it the cold air.

    With the jet stream blocking the warm air pushing north, the residents of the Great Plains have had a quiet month.
