2. Before start Till now, not the all modeling WG members respond to me about their modeling plan. There are few modelers here and modelers are not well coordinated yet. I’m afraid major part of modelers do not have strong interests in AMY08 now. But, I hope after IOP (2008) they will be interested in simulating or validating some events. Thus, it is not early but not too late to call them to AMY08 and coordinate them. This is a simple and private summary based on inputs from some of WG members.

9. On going studies vs Objectives (1) Improve understanding of the ocean-land- atmosphere-biosphere interaction, multi- scale interaction from diurnal to intraseasonal, and aerosol-monsoon water cycle interaction in the Asian monsoon system; JC, JPNC, JPESM, JPCM, JPRM, IN, MAIRS, AIPO, APCC, AU

10. (2) Determine the variability and predictability of the key components of Asian monsoon on intraseasonal to interannual time scales. In particular, the role of land surface processes… –JC, JPHR, APCC, NPOIMS, AIPO, AU (3) Improve physical representation in coupled climate models and develop data assimilation of the ocean-atmosphere-land system in monsoon regions…; –JC, JPNC, JPCM, IN, APCC, AIPO, NPOIMS, AU

11. (4) Develop a hydro-meteorological prediction system (with lead time up to a season), including a real-time monitoring capability and an integrated hydro- meteorological database in Southeast Asia; –JPRM, (GaME-T,…) (5) Better understand how human activities in the monsoon Asia region interact with atmospheric, terrestrial and marine environmental components. – JC, JPESM, JPHR, IN, MAIRS

12. Global modelers are interested in ISV or MJO prediction/predictablity –Kitoh, Satoh, Hendon, APCC Seasonal prediction/precitability –Kitoh, Satoh, APCC Climatic change and monsoon –Kitoh Land surface initialization –Hendon Material transport –Kitoh, MAIRS

13. Regional modelers are interested in Understanding mechanisms of diurnal to seasonal timescale events –Onset and maintenance of monsoon –Significant events –Diurnal variations Material transport Local climate

14. Suggestions Modeling research along with the objective (4) (realtime H-M prediction) should be encouraged during AMY08. To provide common initial data and validate different model results under common validation data and method are necessary: New taskforce? APCC can do that?
