"Currently, the cloud motion data used to derive wind measurements are observed from geostationary satellites. These instruments orbit the equator, obtaining images of the Earth’s surface below to roughly 55 degrees north and south of the equator. Any farther north or south and the satellite image becomes distorted due to the curvature of the Earth. Consequently, wind data predictions based on cloud motion have been most accurate at latitudes lower than 55 degrees."

"This Google Earth add-on displays a near live global cloud layer, automatically updating every 3 hours.
Whatever this is, it is still present. I think Google would have at least fixed this by now.
