Until now, this second gust front has not been studied in great detail because it was difficult to detect without the sophisticated radar and other equipment that was in place last spring during the Wyoming storm, Wurman says.
The UAVs should provide an even better

If researchers can prove that a secondary gust front is associated with the creation of a twister, they can focus on key questions such as how common the phenomenon is, and whether it leads to persistent and dangerous long-lasting tornadoes, Wurman says.

nike dunk approved the unmanned data-collecting airplanes for flights up to 1,000 feet in remote parts of Colorado, Kansas and Nebraska in the past year, says Brian Argrow, director of the Research and Engineering Center for Unmanned Vehicles at the University of Colorado. The UAV in this study, named Tempest, is a lightweight propeller-driven airplane with a 10-foot wingspan, he said.
One UAV will be flown at a time, but the scientists will have backup planes with them in case one is damaged. "We need to sample more storms, and hopefully in 2010, we'll get that opportunity," Burgess says.
Total funding for the Vortex 2 project is about $12 million from various sources, including the National Science Foundation, Burgess says.
This year, 76 tornadoes have been reported, which is 36% of the average, according to Greg Forbes, severe weather expert at the Weather Channel. "We will expect to see an increase in
