An Open Science Conference (OSC) of the Asian Monsoon Years 2007-2012 (AMY) will be held on 26-27 October 2013 in Zhuhai, China. The AMY-OSC will also be organized in conjunction with the WMO Fifth International Workshop on Monsoons (IWM-V) (28-31 October 2013 in Macau). Sessions cosponsored by AMY have been set up in IWM-V as an extension of AMY-OSC. This arrangement provides an opportunity for AMY researchers to interact with the broader global monsoon research and operational forecast communities. AMY stems from grass-root scientific and societal imperatives and includes about two dozens of regional, national and multi-national research projects in the Asian monsoon regions. It has been endorsed by the Joint Scientific Committee (JSC) of the World Climate Research Programme (WCRP), as well as the WCRP Climate Variability and Predictability (CLIVAR) project and the Global Energy and Water Cycle Experiment (GEWEX) project. It has also been identified as a cross-cutting weather and climate activity by the WMO World Weather Research Programme (WWRP) Monsoon Panel in the WWRP Strategic Plan. The AMY-OSC is organized by the AMY Scientific Steering Committee (SSC). The aim of the OSC is to provide a forum to summarize the achievements of AMY projects and for broad monsoon research community to discuss recent advances, current issues, and future prospect on observing, modeling, and predicting the Asian monsoon ranging from diurnal to interdecadal time scales. The OSC will also provide a forum for discussion of future development of international collaboration on Asian monsoon research. The themes of the OSC will center on achievement reports of AMY projects in three major areas: (a) multi-scale interaction (from diurnal cycle to intraseasonal variations), (b) atmosphere-ocean-land interaction and interannual variation and prediction of the Asian monsoon, and (c) monsoon-aerosol interaction. The conference will include both invited reviews and contributed talks and posters. The invited reviews will be presented in both the AMY-cosponsored IWM-V sessions and the AMY-OSC sessions.
