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.
NSSL/CIMMS researchers have developed a novel ground clutter filter that was just endorsed by the NEXRAD Technical Advisory Committee for an engineering evaluation by the NWS Radar Operations Center.
Dual-polarized weather radar can estimate the number of bats in a swarm similar to the way it can estimate the number of raindrops in a cloud.
NSSL deployed the NOAA X-Pol mobile radar in southwestern Colorado over the weekend as part of the Southwest Colorado Radar project to collect data on snowfall in the area. The project continues through the end of February, 2011.
NSSL will collect dual-polarization radar data along with public weather observations during 2010-2011 winter weather events in the Winter Precipitation Identification Near the Ground (W-PING) project. The volunteer surface observations…
The type and amount of winter precipitation is very sensitive to subtle changes in the atmosphere making forecasting winter precipitation difficult. During the months of December and January, NSSL/CIMMS researchers…
Recent analysis of data from NOAA NSSL’s prototype dual-polarization radar during a significant tornado outbreak in central Oklahoma this past spring showed debris from a damaging tornado. This critical information…
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.
