The International Workshop on Monsoons (IWM) provides a forum for researchers, forecasters, and stakeholders/end-users to discuss recent advances in monsoons research and current topics including new observational studies, process studies, and strategic priority setting for modelling/prediction studies, covering weather-to-climate time scales. The emphasis is on addressing monsoon impacts as part of the societal challenges prioritized by the WWRP and WCRP: high-impact weather, water, agriculture, energy, disaster risk reduction, urbanization, and new technologies, in heavily populated monsoon regions around the world. Outcomes from the workshop are expected to facilitate transfer of new science and technology to National Meteorological and Hydrological Services (NMHSs) in these regions.
