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.
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.
Subtle features in thunderstorms captured by rapid scanning phased array radar could alert forecasters to the potential of severe weather.
NSSL will conduct the first experiment to directly compare how forecasters issue warnings based on data provided at current radar update rates, with warnings issued based on faster data updates provided by Phased Array Radar (PAR).
