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
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
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
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.
Recent flooding in Texas and Oklahoma put NSSL’s experimental Multiple Radar Multiple Sensor (MRMS) Flooded Locations and Simulated Hydrograph (MRMS-FLASH) system to a rigorous test, and researchers were pleased.
