Monsoon systemsare among the most complex coupled atmosphere-ocean-land interaction phenomena and have profound impacts on society.They produce much of the rainfall in the tropics and some parts of the subtropics.Monsoon variability is associated with global-scale impacts since the energy releasedby monsoon systems can influence the global circulation. However, it is notoriously difficult to simulate and predict the monsoons at all temporal scales, in NWP, subseasonal-to-seasonal and decadal forecasts.
The global monsoon system,which includes the South and East Asian, Australian, African, andNorth and South American monsoonsinvolves multi-scale interactions within the Earth's atmosphere, ocean, land surface, cryosphere, and biosphere, and is impacted by human activities (land use change, aerosols or greenhouse gas emissions etc.). A better understanding of monsoon physics and dynamics, with more accurate simulation and prediction of monsoon systemsis therefore of a great practical importance to the atmospheric sciences community.
This session invites presentations on all aspects of monsoon physics and dynamics, from the natural and anthropogenicvariability and predictability of the monsoon systems on multiple timescales, to the impact of monsoons on weather and climate extremes (floods and droughts), as well as the links between monsoons and global climate.

Observational, modeling and forecasting studies are welcome, as are those using palaeoclimate modeling or proxy data.
