Nino 1+ 2, 3, 3.4, and 4
Nino 1+ 2, 3, 3.4, and 4 :
In monitoring the equatorial tropical Pacific for the phases of the ENSO cycle, the area has been divided into 4 sections: (1) Niño 1+2 (0o-10o South) (90o West-80o West); (2) Niño 3 (5o North-5o South) (150o West-90o West); (3) Niño 4 (5o North-5o South) (160o East-150o West); (4) Niño 3.4 (5o North-5o South) (170o-120o West). The reason for this is that major atmospheric circulation impacts are related to changes in the pattern of convection in these regions. The Niñno 3.4 and Niñno 4 regions encompass the area where slight increases or decreases in SSTs can have a big impact on where convection is found in the western and central Pacific and are the key areas for monitoring and predicting ENSO events
