Modeling coordination

T. SatomuraKyoto University

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.

Inputted WG members or countries

• Indonesia (Dr. Edvin Aldrian)

• J. Chan

• Japan (Drs. Kitoh, Satoh, Satomura)

• H. Hendon

To be included

• India– CTCZ

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

(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

(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

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

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

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?
