This analysis explores how inertio-gravity waves affect precipitation in the tropical western Pacific, suggesting modulation patterns of convective and stratiform types.
Key Points
Before the Madden–Julian oscillation peak, eastward and westward inertio-gravity waves were major contributors to convective precipitation.
The westward inertio-gravity waves notably became dominant for stratiform precipitation variances during the study period.
Post-peak, the westward inertio-gravity waves stabilized their contributions, while others diminished, impacting both precipitation types.
The findings highlight varying influences of inertio-gravity waves on precipitation stages within MJO events.
