Between May 9 and June 10, 2011, CAPS is producing 50-member 4-km-resolution, multi-model (WRF-ARW, WRF-NMM, ARPS, and COAMPS) storm-scale ensemble forecasts (SSEF) for the full continental U.S. (CONUS) domain, assimilating radial wind and reflectivity data from over 140 WSR-88D radars and other available observations. The daily 36-hour-long forecasts are initialized at 00 UTC (7pm CDT).
These forecasts are run in support of the NOAA Hazardous Weather Testbed (HWT) 2011 Spring Experiment and is a collaboration among CAPS, SPC, NSSL, and DTC, supported by NICS's Cray XT-4 supercomputer at the University of Tennessee.
Additional details can be found in the 2011 CAPS HWT Spring Experiment Plan Document.
Realtime Wind Analyses and Rapidly Updated Forecasts for CASA
CAPS is producing realtime 400-m-resolution low-level wind analyses that are updated every 5 min for CASA
Spring Experiment. Available CASA and other sources of data are going into
the analyses. Furthermore, up to 2-hour-long Very-Short-Range NWP forecasts
at a 1-km resolution are produced every 20 minutes when active weather exists
within the CASA Oklahoma network. CASA analysis and forecasts are produced
on OSCER's Sooner system at the University of Oklahoma, using nearly 2000 processor cores.
