McIDAS images of GOES-13 0.63 µm visible channel data (above; click image to play animation) showed that the effect of strong winds in the wake of an unusually intense storm off the coast of Labrador could be seen in the motion of sea ice in the waters of the Canadian Maritimes on 05 February 2013.

A comparison of AWIPS images of MODIS 0.65 µm visible channel data and the corresponding false-color Red/Green/Blue (RGB) composite at 15:28 UTC (below) demonstrated the value of using RB images for cloud vs snow discrimination (snow and ice appear as darker shades of red in the RGB image). Surface reports plotted on the images showed that 2 sites were reporting wind gusts of 50 knots or higher at that time.

    Top gif anim locks up in Google Chrome?

    This is a very large animated GIF (25 MB) — so it is more likely an issue of how much RAM your computer has, rather than which web browser you are using. The animated GIF plays fine using Chrome on my Mac (which has 4 GB of RAM).
