Description : (La description de cette image n'existe qu'en anglais)
08 Jan 00 - A giant horseshoe pattern of higher than normal sea-surface heights developing over the last year is beginning to dominate the entire western Pacific and Asiatic oceans. Scientists studying the new data believe these abnormally warm ocean temperatures, which contrast with a cool La Niña, may be part of a larger, longer-lasting climate pattern. 'In contrast with the more spectacular but shorter duration El Niño and La Niña events, this multiple-year trend may be part of a decade-long pattern known as the 'Pacific decadal oscillation,'' Patzert said. 'The persistence of these abnormally high and low Pacific sea-surface patterns, along with warmer and colder than average ocean temperatures, tells us there is much more than an isolated La Niña occurring in the Pacific Ocean.'
