http://www.FunToWatch.TV Precipitation has been a major story across the world this past year. Oddly enough, though, the Equatorial Pacific is pretty dry, as shown by the GOES-West satellite's infrared water vapor channel. This image, taken on February 4, 2011 at 1800z shows areas of intense atmospheric water vapor (moisture) in shades of white and green-blue. Dry areas are transparent. Typically the equator has bands of very high water vapor content, due to a combination of evaporation off of the warm ocean surface and general circulation patterns. Its also possible to see in the upper part of the image, an atmospheric river moving across the Pacific and heading towards the Pacific Northwest U.S.
