Subtle features in thunderstorms captured by rapid scanning phased array radar could alert forecasters to the potential of severe weather.
NSSL researchers successfully launched two balloon borne prototype instruments into a large thunderstorm complex at the end of October.
Flash floods are the number one hazardous weather-related killer in the US, yet they remain poorly observed. An NSSL project now collects data from the public on flash flooding, in addition to hail and wind reports.
The NOAA National Severe Storms Laboratory (NSSL) deployed a mobile radar near Durango, Colorado, during the month of August to collect data on thunderstorm rainfall and resulting flash flooding.
Over the past five summers, students have been making thousands of phone calls to collect reports of severe weather from the public as part of the Severe Hazards Analysis and Verification Experiment (SHAVE).
Preliminary numbers show VORTEX2 intercepted about 30 supercells, and 20 weak or short-lived tornadoes.
The goal for the 2010 hurricane season is to demonstrate, in real time, that CI-FLOW can produce realistic simulations of total water level for an actual storm event.
Focused observations of storms lead to faster updates since the radar does not waste time scanning clear-air regions.
The Verification of the Origins of Rotation in Tornadoes Experiment – 2 will begin the second year of data collection on May 1 and run through June 15.
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).
