Recent studies with different models have shown that coupled models produce mean state moisture gradients more favorable for Madden-Julian oscillation (MJO) propagation than those in uncoupled models.
The goal of MSMIP is to understand how tropical sub-monthly sea surface temperature (SST) variability influences tropical mean state moisture patterns and the eastward propagation of the MJO.
MSMIP will address this goal with a series of climate model experiments designed to answer the question “What aspects of coupled model SST anomalies are most important for tropical mean state moisture patterns and MJO propagation: their phasing, pattern, or persistence?»
