Severe weather in Oklahoma this spring has offered opportunities for collecting data.
Seven destructive tornadoes struck Oklahoma on May 24, 2011. The tornadoes were well forecast by the National Weather Service (NWS), and NSSL was in position to capture the storms in several ways.
The NSSL/CIMMS Severe Hazards Analysis and Verification Experiment (SHAVE) are collecting hail, wind damage and flash flooding reports through phone surveys from now through mid-August.
NWS forecasters will be evaluating a new weather-adaptive three-dimensional variational data assimilation (3DVAR) system from NSSL/CIMMS that automatically detects and analyzes supercell thunderstorms during the 2011 Experimental Warning Program in the Hazardous Weather Testbed.
As severe weather approaches central Oklahoma this spring, NSSL/Cooperative Institute for Mesoscale Meteorological Studies researchers will be able to study fast-changing storms using a new radar processing technique.
