Abstract

This study revisits the relations between Madden-Julian Oscillation (MJO) and El Niño that is classified as eastern Pacific (EP) and central Pacific (CP) types. During an EP-type event that produces lasting dry conditions in the Maritime Continent and western Pacific, the MJO activity is weak especially in its 4th-6th phases as a strong response. In contrast during CP-type episodes, the MJO exhibits notably enhanced and suppressed amplitudes in its different phases. The low-level westerly wind anomalies of enhanced MJO impact the CP-type El Niño more than vice versa.
