  1. MJO Breakout Group

  2. MJO Breakout Group Agenda Jim Benedict - Structure of the MJO in MMF Bo-wen Shen - Comparison of CSU & NASA Goddard MMFs Mitch Moncrieff & Duane Waliser - Year of Tropical Convection (YOTC) Duane Waliser - CLIVAR MJO Diagnostics Working Group and the plenary talk …. Bill Rossow - Testing the realism of MMF: Representation of MJO Discussion leaders/items Judith Berner - Stochastic backscatter Marat Khairoutdinov - Conventional parameterization Hiroaki Muira - MISMO- related (MJO initiation) global simulations Mitch Moncrieff - Predictability of the MJO (ensemble approach)

  3. MJO : A CHALLENGE FOR WEATHER & CLIMATE MODELS, A PROBLEM OF MULTISCALE CONVECTIVE ORGANIZATION (WHICH IS NOT REPRESENTED BY CONTEMPORARY PARAMETERIZATIONS The MJO: A comprehensive modeling/prediction/validation problem Weather and Climate models (parameterized convection) Probabilistic (ensemble) models (parameterized convection) High-resolution NWP models (hybrid convective parameterization) Superparameterized models (explicit convection) Regional and global CRMs (explicit convection) Theoretical insights … comprehensive models call for comprehensive validation

  4. Priority activities • Representation of the MJO in CMMAP MMF, and comparison with other MMFs • Nature of convective organization in CMMAP MMF MJOs (e.g., initiation, lifecycle, thermodynamic & dynamical structure, propagation, etc.) • Evaluation of CMMAP MJOs against observations e.g., satellite data • Parameterization
