VORTEX

From Wikipedia, the free encyclopedia

NSSL vehicles on Project VORTEX, equipped with surface measurement equipment.

Verification of the Origins of Rotation in Tornadoes Experiment or VORTEX, is a field project that seeks to understand how a tornado is produced by deploying around 18 vehicles that are equipped with customized instruments used to measure and analyze the weather around a tornado. The project has also stated that it is interested in why some supercells produce tornadoes while others do not. It also concerned itself with why some supercells form violent tornadoes versus weak tornadoes. The original project took place in 1994 and 1995, and another project was run in 1999.

The movie Twister was at least partially inspired by the VORTEX project.

A second VORTEX project, named VORTEX2 is being planned for 2009-10.
