  9. The Effect of Orbital Forcing on the MJO’s Amplitude and Phase Speed

    Rushley, Stephanie2020

    The Madden-Julian Oscillation (MJO) has a pronounced seasonal cycle, drifting from the Southern Hemisphere in boreal winter to the Northern Hemisphere in boreal summer, with a maximum intensity during boreal winter in the Southern Hemisphere. The reason for this maximum intensity during boreal …

  10. The Madden-Julian Oscillation and Convective Aggregation

    Davison, MatthewUniversity of Cambridge2024

    The Madden-Julian oscillation (MJO) is a region of enhanced precipitation which forms every 30-60 days over the Indian Ocean and slowly propagates to the east over the Pacific. Despite being the dominant mode of intraseasonal variability in the tropical troposphere, most numerical models struggle …
