21. Contribution to AMY APCC/CliPAS Hindcast WCRP/TFSP Dataset –AMY should consider making an organized analysis of existing hindcast datasets through APCC/CliPAS project and the planned WCRP Task Force on Seasonal Prediction (TFSP) Climate-system Historical Forecast Project (CHFP), identifying a range of suitable metrics relating to the AAM for application to the outputs, to (a) assess seasonal prediction skills and identify common weakness of the current dynamic predictions of the Asian monsoon, (b) determine the predictability of Indian Ocean Dipole which is an objective of the Indian Ocean Panel, and (c) study the role of the MJO in the onset of the (1997) El Niño, which is a joint effort between AAMP and Pacific Panel (PP). Coordinated Monsoon ISV Experiment –In order to determine predictability and predictive skills of the Asian monsoon on intraseasonal time scales, a coordinated sub-seasonal prediction activity on monsoon variability is recommended. The US-CLIVAR MJO working group has designed metrics for evaluation of model simulations and measure of ISO prediction skill. AMY should take advantage of these metrics for diagnostic analysis. The MJO WG has also attempted to predict the lifecycle of MJO at several operational centers worldwide. AMY should encourage an organized effort to pursue prediction of monsoon ISO. The main focus of AMY should be placed on boreal summer monsoon onset, active/break phases and retreat of the summer monsoon. Both AGCMs and coupled GCMs can be used. Both hindcast and real time prediction are encouraged. High resolution modeling –It is recommended that coordinated multi-high resolution model ensemble experiments be organized to investigate sub-seasonal to interannual factors that influence extreme events, such as tropical cyclones, severe droughts, devastating floods. The coordinated high resolution modeling proposed by Sieg Schubert at NASA has been endorsed by CLIVAR/AAMP and APCC, and forms a very useful starting point for developing high resolution modeling activity.

24. OPeNDAP ( Open-source Project for a Network Data Access Protocol) What the Opendap can do? Opendap handles transport, translation and subsetting of data. Opendap allows us to access remote data over the internet : – using familiar data analysis and visualization packages like GrADS, Matlab, Ferret, IDL,... as if the data were on your computer – without worrying about data storage formats, translating them on-the-flight (including in ascii), if necessary – accessing only the data of interest (extracting geographical area, time series...)
