  4. Four Regional Components of MAHASRI

  5. MAHASRI Objective "To establish hydro-meteorological prediction system, particularly up to seasonal time-scale, through better scientific understanding of Asian monsoon variability".

  6. Key Science Issues (1) • Atmosphere-ocean-land interactions in the Asian monsoon system • Role of orography on monsoon rainfall • Scale-interactions among diurnal, synoptic, intraseasonal and seasonal variability of Asian monsoon • Interactions of surface and boundary layer processes with convective cloud system • Comparisons of hydro-meteorological characteristics among regional monsoon sub-systems

  7. Key Science Issues (2) • Effect of human influences (i.e., aerosols, land-use change, and greenhouse-gas increase) on hydro-meteorological variations in Asian monsoon regions • Down-scaling and up-scaling for/with regional hydro-meteorological modeling and forecast • Transferability of land-surface hydrological models and parameters for prediction of ungauged basins • Incorporation of new technologies for observation and computation

  8. International cooperation strategies • Facilitate and/or improve hydro-meteorological observations in Asian monsoon countries in conjunction with GEOSS • Cooperate with CEOP-II by observations, data and hydrometeorelogical studies in Asian monsoon • Contribute IPY by conducting intensive observations in Asian monsoon region • Capacity building for observation, analysis, data-integration and modeling • Data exchange to establish an integrated database

  9. Differences from GAME？ • More concrete collaboration with Asian hydrometeorological agencies and research institutes 　→ Present proto-type model for the hydrometeorological prediction system • Expansion the target field not only air-land interaction but also air-land-sea interaction, thus closer collaboration with CLIVAR community • Expansion of the target area over the Maritime Continent, Western Pacific, and India, while retreat from Siberia • Targeting also winter monsoon • Main time-scale: weekly to seasonal for prediction, year-to-year variability for research including long-term data rescue
