SPC Evaluation: Steve Weiss
SPC had only limited opportunities to examine the parallel runs of the HRW WRFs during the summer 30 day evaluation period.
More importantly, however, we have been utilizing the once daily experimental WRF-NMM4 in both the annual Hazardous Weather Testbed Spring Experiment activities and daily operational severe weather forecasting at SPC since April 2004.
This convection-allowing model was first tested during the 2004 Spring Experiment, which focused on exploring the utility of high resolution versions of the WRF-NMM, as well as WRF-ARW models from NCAR and OU-CAPS, to provide useful guidance for severe weather forecasters.
Spring Experiments examining WRF-NMM and WRF-ARW models were also conducted in 2005 and 2007, where intensive tests and evaluations were again conducted daily during severe weather episodes across the central and eastern U.S.
