Over the global tropics, the Madden-Julian Oscillation (Madden and Julian 1994, MJO) explains a significant amount of the variability in circulation and convection on intraseasonal time scales. However, significant variation exists in the spatial extent and seasonal occurrence of the MJO. While the upper-level divergent flow associated with MJO is often traced around the globe, the low-level wind circulations and regions of enhanced and reduced deep convection have maximum amplitudes over the Indian and Pacific Oceans. Furthermore, the MJO appears to be stronger during the Northern Hemisphere winter.
