Meteorologists from the Center for Severe Weather Research began their annual field research project this week, pursuing supercell storms and watching for the formation of tornadoes. A supercell--usually, but not necessarily, a thunderstorm--contains a deep and persistent rotating updraft called a mesocyclone.

The Doppler on Wheels vehicle scans a supercell thunderstorm in Elbert County near Agate, Colo. The truck can carry the radar directly into storms, allowing scientists to scan storms and tornadoes and make 3-D maps of wind and debris.

Tim Marshall, a 40-year veteran of storm chasing, watches a supercell near Agate, Colo.
The team hopes that gaining knowledge about tornado formation and structure will result in better predictions, saving lives and property.

Tim Marshall looks out the window of a tornado scout vehicle as the group tracks a supercell thunderstorm in Quanah, Texas.
Marshall became interested in weather after an F-4 tornado passed about a half-mile from his home in Oak Lawn, Illinois, when he was ten years old. The 1967 tornado killed 33 people and injured 500.
Center for Severe Weather Research intern Hunter Anderson prepares tornado pods as a severe thunderstorm moves into the area in Paducah, Texas.
The storm did not produce a tornado, but the group was prepared to deploy the pods if one developed. The pods are heavy, metal discs with instruments that measure and map winds at ground level.
