AbstractThe features of the MJO during two types of El Nio events are investigated in this paper using the daily NCEP-2 reanalysis data, OLR data from NOAA, and Real-time Multivariate MJO index for the period 1979-2012. The results indicate that the MJO exhibits distinct features during eastern Pacific (EP) El Nio events, as compared to central Pacific (CP) El Nio events. First, the intensity of the MJO is weakened during EP El Nio winters from the tropical eastern Indian Ocean to the western Pacific, but enhanced during CP El Nio winters. Second, the range of the MJO eastward propagation is different during the two types of El Nio events. During EP El Nio winters, the MJO propagates eastwards to 120A degrees W, but only to 180A degrees during CP El Nio winters. Finally, the frequency in eight phases of the MJO may be affected by the two types of El Nio. Phases 2 and 3 display a stronger MJO frequency during EP El Nio winters, but phases 4 and 5 during CP El Nio winters.
