What hindered the E1 Ni(n)o pattern in 2014?
At the beginning of 2014, an E1 Ni(n)o event was predicted to occur in the following winter.However, the E1 Ni(n)o that started to develop in 2014 was hindered in the boreal summer, and only the ocean reached a weak El Ni(n)o condition.This outcome was largely attributed to a suppressed ocean-atmosphere interaction caused by anomalous easterly winds in the eastern equatorial Pacific.These winds were related to negative sea surface temperature anomalies (SSTAs) in the southeastern subtropical Pacific (SESP).The negative phase of the Interdecadal Pacific Oscillation(IPO) laid the foundation for the persistence of cooler SSTAs and enhanced trade winds in the SESP after the year 2000.As the recent IPO downward trend continued,the SSTAs in SESP reached an extremely low value in 2014 and imposed a serious obstacle to the evolution of a warming event.
