La Nina event. Coloured satellite map of the Pacific Ocean showing a La Nina event (purple). This image was taken on 11 July 1998. Areas with a lower sea level than average are blue/purple (generally meaning they are cold). Higher areas are red/white. The La Nina event is a large body of relatively cool water which can influence weather systems throughout the world. Above the La Nina system is the remnant of the complimentary El Nino event (red/white),which dominated the eastern Pacific Ocean in 1997/98. The Pacific Ocean varies between El Nino and La Nina events with no fixed cycle. This image was created using data from the US/French TOPEX/Poseidon satellite | |
