QPF Bombs and Getting the Most Out of Your Model

Thursday, March 27th, 2008

Above is an example of two model forecast runs (12 hours apart).  The main difference comes when looking at the QPF amounts generated over ERN ND and NWRN MN between the two model runs.  The later model run on the right is able to transport more moisture to the north as opposed to the earlier run with the large QPF Bomb over ERN KS and WRN MS.  To learn more about NWP model’s ability to discern these bombs and what useful information you can still glean from “contaminated” output, please see this helpful web module put together by Pete Manousos a few years ago, by clicking here.    

Highlights from the Dec. 11-12, 2007 “Review of the NCEP Production Suite” Conference

Wednesday, March 19th, 2008

Not to diminish the importance of the entire two day conference, this is just a “good parts,” slightly abridged review and link(s) to information concerning the NWP models from NCEP that we can use. 

  • Progress on Future NCEP Production Suite:” - presented by Steve Lord, the director of the Environmental Modeling Center (EMC), diagrams and highlights where EMC, NCEP and the models are headed in the future (some near and some far).
  • National Unified Operational Prediction Capability (NUOPC) Update:” - Presented by Fred Toepfer, EMC’s Deputy Director announces a Navy, NOAA, and Air Force initiative to coordinate efforts to build a new National Global Ensemble Operational Predictive Capability that will: –accelerate improvements in operational performance–create opportunities for a more focused Nationalresearch effort–leverage scarce resources•Provide useful information quickly to the research community
  • NCEP Central Operations:  NCEP Central Operations Timeline for the next few years.  
  • Review by OPC:  Ocean Prediction Center Review NCEP, by SOO and acting Chief of the Ocean Applications Branch, Joe Sienkiewicz.  This includes the multi-grid wave model ensembles, and forecast verification.
