Description:

There has been significant progress in understanding physical phenomena related to tropical convection, MJO, monsoons, and their teleconnections with midlatitude weather and climate. Global earth system models are improving in their ability to represent these phenomena. However, we have made little progress in improving S2S prediction that provides operational products that meet the S2S needs for potential users such as water managers, agriculture, fisheries, energy and defense. National Research Council studies and a recent survey by the Federal agencies have attempted to highlight needs for S2S prediction, yet a clear path to success remains elusive. A joint Federal effort to address S2S prediction has been proposed if a tractable path can be described.

We invite presentations addressing impediments to the successful development of S2S user products, proposed user products, metrics for evaluating products to improve user acceptance, and identification of critical areas for earth system model improvement.
