The material in this session is designed to introduce you to ten of the most commonly encountered or significant misconceptions about NWP models, and to dispel these misconceptions with the truth about what these models actually do and how they may be used intelligently. This “top ten” list should not be considered exhaustive, by any means, but rather a sample of misconceptions from each of the main components of NWP models, including:
We hope to encourage use of the COMET web-based training on NWP through giving a flavor of the material therein contained in this lesson.
NOAA/NWS students – to begin the training, use the web-based video, YouTube video, or audio playback options below (if present for this session). Certificates of completion for NOAA/NWS employees can be obtained by accessing the session via the Commerce Learn Center

COMET Numerical Weather Prediction Professional Development Series
The course provides a pathway through the most important sections of these modules, but each can be viewed independently and in their entirety:
For specific information about the operational models (topography, resolution, physics parameterizations, data used in model analyses, etc.), use the one-stop shopping Operational Model Matrix page. This also has links to the above NWP training modules.
A series of case studies illustrating some operationally significant aspect of the NCEP models will be developed during mid-2001. The first is already online: When Good Models Go Bad: Eta, SSTs, and Prediction of the December 30, 2000 East Coast Snowstorm, Available here
Experience in using numerical weather prediction models in an operational environment is very helpful. This is a basic to intermediate course. Those who have taken coursework in numerical weather prediction will find some of the information basic, depending on the emphasis of that course (numerics and dynamics alone, or additional coverage of physical parameterization methods). The reference section below gives links to source material for additional discussion of the inner workings of NWP models, to help the students gain additional understanding of how to intelligently use the information that NWP models provide to make the most accurate forecast possible for their CWA.
