General Description
The analysis and forecast animations created here are produced by the Department of Earth and Atmospheric Sciences at the University of Albany/SUNY. All fields are computed using 6-hourly pressure-level data from the 1.0x1.0 degree National Center for Environmental Prediction-Global Forecast System (NCEP-GFS) forecasts out to 180-hours. The raw NCEP-GFS data was smoothed using a Gaussian filter with a weight of 25, unless otherwise noted, to produce cleaner results for the QG diagnostics. Diagnostics are computed globally, but are displayed in the subdomain chosen by the user. A detailed description of the fields displayed on each set of images is provided in the User's Guides, and as headers and captions on the animations themselves. Please note that this analysis/diagnostic system is still under development. While every attempt is made to keep the images as up-to-date as possible, it is possible that there will be interruptions to the image generation services as system updates occur.
This work is supported by the University at Albany/SUNY.
- Sutcliffe Development Theory Use the pull-down menus, stratified by geographical region, to select the field you wish to animate, then press the Build Animation button to generate the requested animation. Each animation includes a 10-day analysis archive and the current 180-hour forecast. The new forecast images update approximately 7-10 hours after initialization time (e.g., 1200 UTC forecast available by 1900-2200 UTC).

Thanks to all (in particular Lance Bosart, Howard Bluestein, Chuck Doswell, and Ron McTaggart-Cowan) who have submitted comments and suggestions (some of which have yet to be implemented!) with regard to this page.

I am currently moving the calculations to a new linux box here at DEAS/UAlbany. During this transition, additional geographical regions will be added. You may also notice that the analysis archive for North America will become temporarily intermittent.
