BACKGROUND

1. Winds are estimated at 10 minute intervals from the automated satellite winds algorithm under development for GOES-R at the Cooperative Instutute of Meteorological Satellite Studies (CIMSS), University of Wisconsin-Madison.  Sequences of three GOES-14 images, separated by 3 minutes (visible), 5 and 10 minutes (IR, SWIR and WV) are used to compute winds.

2. Objectively analyzed fields at 850, 700, 500 and 300 hPa (based on available wind vectors and background field from global forecast model GFS):

HTML5 based applications used for interactive animations were developed by Tom Whittaker of the Space Science and Engineering Center  SSEC, University of Wisconsin-Madison.  The animations can take a while to load, depending on network speed, computer systems, etc.
