NCAR's David Dowel is one of two scientists coordinating field operations for the massive VORTEX2 field campaign, which sends mobile units teeming with sensors across a study area spanning more than 900 miles, from west Texas to southwest Minnesota, in pursuit of tornadoes. He and Erik Rasmussen of Rasmussen Systems work with a forecasting team to figure out which storms in the study region are most likely to produce a tornado. The problem? That question--which storms are most likely to form tornadoes--is exactly what the VORTEX2 study is trying to answer. Dowel describes how they home in on the best targets, down to the county level, in pursuit of the "magical 30 minutes" before a tornado spins up.
