NEW SATELLITE ANIMATION SHOWS EL NIÑO IN ATMOSPHERE

       New satellite animation shows the movement of water vapor over the Pacific Ocean during the 1997 El Niño condition. Higher than normal ocean water temperatures increase the rate of evaporation, the resulting warm moist air rises into the atmosphere, altering global weather patterns.

       The animation was created from data obtained by the Microwave Limb Sounder (MLS) instrument onboard NASA's Upper Atmosphere Research Satellite (UARS) from late December 1996 to late December 1997.

       A NASA TV video file will feature the new animation at 9 a.m., noon, 3, 6, 9 p.m. Pacific Time today. NASA Television is available on GE-2, transponder 9C at 85 degrees West longitude, with vertical polarization. Frequency is on 3880.0 megahertz, with audio on 6.8 megahertz.

       In addition, the most recent still images of the El Niño water vapor are now available online at:

       The MLS instrument is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology.
