Modeling, Analysis, Predictions and Projections (MAPP)

Cold spells are defined as a rapid fall in temperatures within a 24-hour period and can harm crop and fruit farms.

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 research team funded in part by CPO's MAPP and CVP Programs investigate the effect of global warming on the MJO. 

A well-known gap in prediction skill extending from two weeks to several months exists in our climate modeling systems. With the inability of climate models to include all local and mesoscale land and atmospheric processes, reliable subseasonal forecasts and predictions have been difficult to produce.
