Description:

Tropical convective variability on intraseasonal timescales, including especially the Madden-Julian Oscillation and the Boreal Summer Intraseasonal Oscillation, provide important sources of tropical subseasonal-to-seasonal (S2S) predictability. Via teleconnections, these processes can further alter global circulation patterns and influence the S2S predictability of many other aspects of the Earth system, with important societal implications across many sectors. We invite observing, modeling, and forecasting studies aimed at identifying, quantifying, and/or leveraging S2S predictability offered by tropical convective variability. We welcome presentations from the entire research-to-operations (R2O) spectrum, hoping to further strengthen collaborative ties between these communities.
