Researchers have for years been working to tackle the subseasonal to seasonal (S2S) prediction problem to improve forecasts. The Subseasonal Experiment, SubX, is an interagency research-to-operations project designed to help tackle this problem. The results of the project were recently published in BAMS. 

A new review paper describes how MAPP-funded and organized work has contributed to recent progress in understanding tropical cyclones.

Since 2016, the Subseaonal-to-Seasonal (S2S) Task Force has been focusing efforts on bridging the skill gap between weather and seasonal prediction lead times. Publication of this special collection represents an important milestone for the group.

The Madden-Julian Oscillation (MJO) is responsible for major shifts in tropical weather on weekly and monthly timescales with impacts around the earth.

Stratospheric ozone information is consistently measured to a high degree of accuracy and can now be used for seasonal forecasting in North America which has major applications such as informing public health and agricultural decisions.
