Some Great Knowledge, Papers, and Training Materials That You May Have Missed

Thursday, May 1st, 2008

Below are some links to, or copies of, some perhaps lesser known meteorological training materials.  Many of these have been born out of Aviation Weather programs either here in the USA through the military Air Force Weather Agency (AFWA) or the FAA, or from up north and our Canadian Neighbors.  Although some of the information is based on region specific examples, all of it (the principles, etc.) can be applied to most of our own geographic areas. 

First up is a link to NAV Canada, a privately run non-profit organization that operates Canada’s Civil Air Navigation Service.  This section contains an in depth training manuals section that is broken into six geographic regions that cover the whole of Canada.  Truly indispensable stuff here for all but tropical forecasters: NAV Canada Maunuals

Next up is the Air Force Weather Agency’s “Meteorological Techniques” which is an in depth compilation of many various weather forecasting parameters and techniques.  It is another truly indispensable item to be used for review, support, rules of thumb (tricks of the trade).   Also by AFWA, great training, practice, and supplemental review is the manual of the Mesoscale Forecast Process

This paper by John Mecikalski and Kristopher Bedka titled, “Forecasting Convective Initiation by Monitoring the Eveolution of Moving Cumulus in Daytime GOES Imagery” is a little long in the tooth (title-wise), but is definitely worth a read. 

More in the way of research papers / training materails will be posted here from time to time.  If you know of some lesser known, but valuable training for those of us in the weather business, please send us the information so that we may pass in on to others.�

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.
