Subseasonal to Seasonal Prediction Project




Sub-seasonal to Seasonal Prediction - Research Implementation Plan

Subseasonal to Seasonal Prediction Initiative Flyer (October 2012 version)


The main goal of the proposed WWRP/THORPEX/ WCRP joint research project is to
improve forecast skill and understanding on the subseasonal to seasonal timescale, and promote its uptake by operational centres and exploitation by the applications community. Specific attention will be paid to the risk of extreme weather, including tropical cyclones, droughts, floods, heat waves and the waxing and waning of monsoon precipitation. Work will be guided by a steering group that will work in conjunction with appropriate WMO bodies and other relevant structures.
