El Nino is the disruption of Ocean Atmosphere system in the tropical Pacific having serious consequences on weather around the globe. One of the ways to study this global Climatic Change is to study the temperature variation. The four dimensional maps of temperature from 1978-1997 for the United States obtained through space-time analysis (~1 Gigabyte of original information) based on 3D KZ filtration will be presented. It is very hard to imagine simultaneous random behavior over a huge geographic region, for a comparison of short term synoptic and seasonal components, which has about 10 times higher variation in any location as compared to El Nino wave. Nevertheless in space they are very strongly correlated. They are becoming nonrandom when observed in space. Study shows long term time-space fluctuations of temperature exists and is predictable in 4D space for about a year ahead in each location. Map of temperature trends will be presented separately.
