    • MJO Task Force Dynamical Model MJO Forecasts

    The U.S. CLIVAR program instituted a MJO working group to study and develop diagnostics and metrics related to various components related to the MJO during 2006. A subgroup was organized to focus on MJO operational prediction and was tasked to develop a MJO forecast metric for comparison of dynamical models from operational global prediction systems. The decision was made for NCEP / CPC to host the application, display, and evaluation of these MJO model forecasts. During 2010, the group was reformulated as the WCRP/WWRP-THORPEX YOTC Task Force. Below are links to the MJO model forecasts, the MJO Task Force home page and the U.S. CLIVAR MJO Working Group original home page.
