General Description
The analysis and forecast animations created here are produced by the Department of Atmospheric and Environmental 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 144-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. While every attempt is made to keep the images up-to-date, it is possible that there will be interruptions to the image generation services as system updates occur.
- Sutcliffe Development Theory Use the matrix to select the field you wish to animate. Each animation includes a 10-day analysis archive, while a subset of the animations (highlighted in blue) include the most recent 144-hour forecast.
