Propagation of the Madden – Julian Oscillation and scale interaction with the diurnal cycle in a high ‐ resolution GCM

The Madden–Julian Oscillation (MJO; Madden and Julian 1971, 1972, 1994; Zhang 2005) is the greatest source of variability on intra-seasonal time scales throughout the tropics. It consists of alternate large-scale envelopes of active and suppressed convection propagating slowly (∼5 m s) eastwards from the Indian Ocean to the Pacific Ocean, and an associated… CONTINUE READING
