Hydrometeorological disasters are the most recurring and devastating natural hazards in the world, directly impacting human lives and causing severe economic damage through property loss. The US and Asia face similar challenges in observing, understanding and forecasting hydrometeorological events, in particularly associated with extremes and high-impact events. This session is aimed at fostering and promoting communications and collaborations among US and Asian countries through information exchange on science advances, technology and infrastructure capabilities, data, and common practices. We invite contributions dealing with all aspects of hydrometeorological studies including in-situ and satellite observation, data assimilation, atmospheric and hydrologic process studies and modeling, and weather and hydrologic forecasting on timescales from days to seasons. We particularly welcome US-Asian joint research in those areas.
