Tornadoes Wreak Havoc
About 105 people have been killed by tornadoes since the beginning of this year. According to the reports some 868 tornadoes have struck through May 18. The tally is on par with 2004, in which a record 1,819 tornadoes were reported, National Weather Service Storm Prediction Center, in Norman, Okla., said.
“It will be one of the biggest years when all is said and done,” said Harold Brooks, a meteorologist at the center. “It’s been very, very active and very unusual.” The 136 tornadoes reported in January 2008 were about 7 times higher than the January average of 19 for the 1953 to 2005 period. The February record at 232 was 11 times higher than the previous February average of 21 tornadoes.
“Our work suggests that the trend, the sign, is that conditions for severe weather will increase,” said Robert J. Trapp, an associate professor of atmospheric science at Purdue University. (Source)
A sequence of images showing the birth of a tornado. First, the rotating cloud base lowers. This lowering becomes a funnel, which continues descending while winds build near the surface, kicking up dust and other debris. Finally, the visible funnel extends to the ground, and the tornado begins causing major damage. This tornado, near Dimmitt, Texas, was one of the best-observed violent tornadoes in history.
This sequence of three photographs was taken by a member of the VORTEX project outside of Dimmit, TX on June 2, 1995. Known to some as the most studied tornado of all time, multiple movies, radar images, photographs, and damage observations were made for this tornado’s entire lifespan by members of the VORTEX team.

What about the hurricanes?
