Possible Scenario on the Development of Rainfall Anomaly


Increase of Rain to the East of SSTA
Eastward development of Warm Kelvin response
Low Pressure along the Equator
Ekman Flow Converging to the Equator
Moisture Convergence enhances Rainfall

Decrease of Rain to the West of SSTA
Westward development of Warm Rossby response
Relative High Pressure along the Equator
Ekman Flow Diverging from the Equator
Moisture Divergence suppresses Rainfall
