This is an Intermediate level session.

The material in this session is designed to increase your understanding of medium range forecasting.
The Objectives for the session are:
• Review the reliability of D-3, D+0, and D+3 500 mb mean charts as predictors.
• Investigate model errors based on particular mean patterns.
• Understand how a changing mean pattern leads to changes in the character of model errors ... including the time lag factor.
• Understand how diagnosis of model bias provides an additional tool in helping anticipate individual forecast shortwave errors.

A.) The interactive VISITview training session. (To be used with a VISIT instructor leading the session ). Click here to signup for teletraining. The session will last 75 minutes. This teletraining session uses the VISITview software, where Windows PC (with 64 MB RAM or greater) with an Internet connection is needed.

B.) Web-based training session - a "stand alone" version viewed via a Web browser, with embedded talking points included. This lesson version may be viewed at any time. These slides are ideal for printing from the web-browser, just print preview first to choose portrait or landscape mode. Best viewed with Internet Explorer or Netscape (prior to version 6).

C.) Web-based Visitview session - This version uses the VISITview software within a Web browser, may be viewed at any time. It retains all the functionality of the VISITview software which you see in a "live" teletraining session. The talking points are not included in this lesson version, but can be viewed in a separate Web browser (or printed out beforehand).

D.) local Visitview session - This is the same version of the lesson used in a "live" VISITview teletraining session, but no connection is made to an external VISITview server. You may download the file off this page and go through the lesson on your own in "local mode" by starting the "visitlocal.bat" file. Talking points are not included in this lesson version, but can be viewed in a separate Web browser ( or printed out beforehand).

• EMC ensembles (including color-coded spreads): http://www.emc.ncep.noaa.gov/projects/index.html
  Directions:After typing in the address http://www.emc.ncep.noaa.gov/projects/index.html and hitting "enter", then scroll down to Medium Range Ensemble Prediction System hit enter, then click on "Ensemble Mean and Spread Plots." then choose your forecast time either for either sea level or 250 millibars.

Talking points - these may be used by local offices in tandem with the visitview training session (run in local mode - "visitlocal.bat"). The talking points may be printed out to easily review the session in detail at any time. The web page version contains talking points embedded in each slide (useful for printing).
