Most National Meteorological and Hydrological Services (NMHSs), particularly those of developing countries, do not have the expertise to downscale GCM outputs to local climate conditions. Under this project, a training course was carried out, which combined the lectures, sharing of experience, and computer lab sessions for development of downscaling tools for regional climate prediction, resulted in enhancement of the capacity of climate prediction over the Asia-Pacific region. Participants from NMHSs of the Philippines, Thailand, and Vietnam learned how to make downscaling predictions based on existing the existing APEC Climate Center (APCC) Multi-Model Ensemble (MME) global seasonal forecasts. For NMHS’ use, APCC provides access to its forecasts in digital data format via internet, as well as access to Climate Information Tool Kit (CLIK) developed for climate data processing and analysis, that implies implementation of the received knowledge and skill in the national climate prediction institutions of the participants.
