Leveraging the MJO for Predicting Envelopes of Tropical Wave and Synoptic Activity at Multi-Week Lead Times
Abstract
The Madden-Julian Oscillation (MJO) is the dominant mode of tropical intraseasonal variability, and it extensively interacts with other components of the climate and weather systems. In this project, we will focus on its interactions with important higher-frequency tropical modes. The long-term goals are 1) to explore the relationships between the MJO and the tropical synoptic variablility, mainly the convectively coupled equtorial waves (CCEWs) that include Kelvin, equatorial Rossby, mixed Rossby-gravity, Inertio-gravity waves, and tropical depressions; 2) to investigate the physical mechanisms behind these relationships; 3) to explore the predictability and prediction skill of the envelopes of these tropical synoptic waves associated with the MJO, thus contributing to forming a seamless bridge between weather and climate prediction.
