SitatTrade winds: Strong westerly wind anomalies are present in the tropical Pacific west of the Date Line while trade winds are near-average along in the eastern half of the tropical Pacific (see anomaly map for the 5 days ending 23 February). This is the second strong westerly wind burst this year, with the first occurring between 19 and 30 January. During La Niña events, there is a sustained strengthening of the trade winds across much of the tropical Pacific, while during El Niño events there is a sustained weakening of the trade winds.
SitatSouthern Oscillation Index: The Southern Oscillation Index (SOI) has continued to drop over the past two weeks as was expected. The latest approximate 30-day SOI value to 23 February is +2.6, well within the neutral range. Sustained positive values of the SOI above +8 may indicate a La Niña event, while sustained negative values below −8 may indicate an El Niño event. Values of between about +8 and −8 generally indicate neutral conditions.
SitatENSO Update – March 2014Posted on March 24, 2014 by Bob Tisdale Just about all indicators are pointing to a moderately strong El Niño for the 2014/15 ENSO season. See the NOAA weekly ENSO update dated March 24, 2014. The subsurface temperature anomalies along the equatorial Pacific associated with the downwelling (warm) Kelvin wave are quite warm....
Sitat fra: Jostemikk på mars 25, 2014, 05:58:40 AMSå gjenstår å se om dette skjer, og ikke minst, hvor mye varmtvann som finnes og frigis denne gang. Det dette i så fall vil føre til, er en varm utgang av 2014, og en varm start på 2015. De neste årene vil bli kjøligere.Det er så en kan grue seg, for i kjent AGW-stil vil et varmt El Niño-år skyldes AGW, mens et kaldt La Niña-år skyldes ENSO.
