2015 PARISE Experiment

2015 PARISE Experiment

This week, researchers from NOAA’s National Severe Storms Laboratory will launch the 2015 Phased Array Radar Innovative Sensing Experiment to assess the impacts of rapidly updating radar data on forecasters’ warning decision performance. The project will be carried out over the course of six weeks, and will conclude on September 25. As in previous years,

Hydrometeorological Testbed 2015

Hydrometeorological Testbed 2015

During the week of July 20-24, six forecasters from NWS offices nationwide joined NSSL and CIMMS researchers for the final week of the Hydrometeorological Testbed. This project was supported by JJ Gourley, Steve Martinaitis, Race Clark and Zac Flamig. During the week, the forecasters issued experimental watches and warnings for hydrologic extremes in real-time, with

Significant Paper: 31 May 2013 El Reno Tornadoes: Advantages of Rapid-scan Phased Array Radar Data from a Warning Forecaster's Perspective

31 May 2013 El Reno Tornadoes: Advantages of Rapid-scan Phased Array Radar Data from a Warning Forecaster’s Perspective. Authors: Kuster, C.M., Heinselman, P.L., Austin, M. Journal: Weather and Forecasting  Publication Date: Online 6/12/15 Important conclusions:  Researchers collaborated with the forecaster who issued real-time tornado warnings for the 31 May 2013 supercell near El Reno Oklahoma. The forecaster compared critical radar signatures frequently

Significant Paper: Automated Detection of Polarimeteric Tornadic Debris Signatures using A Hydrometeor Classification Algorithm

Automated Detection of Polarimeteric Tornadic Debris Signatures using A Hydrometeor Classification Algorithm Journal: Journal of Applied Meteorology and Climatology Publication Date: Online 7/2/2015 Authors: Snyder, Jeffrey C., Ryzhkov, Alexander. Important conclusions:  Since debris lofted by tornadoes has scattering characteristics that are distinct from those of hydrometeors, the additional information provided by polarimetric weather radars can aid in identifying debris from tornadoes.  The polarimetric tornadic

NSSL researchers lead project to evaluate experimental flash flood products

NSSL researchers lead project to evaluate experimental flash flood products

During July, NOAA National Weather Service forecasters from forecast offices and river forecast centers will assess emerging hydrometeorological concepts and products in the Multi-Radar / Multi-Sensor (MRMS) Hydro Experiment 2015. Their goal is to improve the accuracy, timing, and specificity of flash flood watches and warnings.
