VORTEX2 Tornado Scientists Hit the Road Again
2010 expedition takes place May 1st though June 15th
In the largest and most ambitious effort ever made to understand tornadoes, more than 100 scientists and 40 support vehicles will hit the road again this spring.
The project, VORTEX2--Verification of the Origins of Rotation in Tornadoes--is in its final season: May 1st through June 15th, 2010.
VORTEX2 is supported by the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administration (NOAA).
Scientists from more than a dozen universities and government and private organizations will take part. International participants are from Italy, Netherlands, United Kingdom, Germany, Canada and Australia.
The questions driving VORTEX2 are simple to ask but hard to answer, says lead scientist Josh Wurman of the Center for Severe Weather Research (CSWR) in Boulder, Colo.
"Current warnings have only a 13-minute average lead time, and a 70 percent false alarm rate," says Brad Smull, program director in NSF's Division of Atmospheric and Geospace Sciences. "Can we issue reliable warnings as much as 30, 45 or even 60 minutes ahead of tornado touchdown?"
VORTEX2 scientists hope to find the answers.
They will use a fleet of instruments to literally surround tornadoes and the supercell thunderstorms that form them.
An armada will be deployed, including:
"VORTEX2 is fully nomadic with no home base," says Wurman. Scientists will roam from state to state in the U.S. Plains following severe weather outbreaks.
"When we get wind of a tornado," says Wurman, "we spring into action."
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
