A069:
Monsoons of the Americas: Observations, Intraseasonal to Interannual and Interdecadal Variability, Climate Change and Extremes





Session ID#: 25112

Session Description:
Tropical and subtropical regions of North and South America feature summertime monsoon circulations, associated with seasonal changes in regional precipitation. These monsoons are of vital importance for regional water resources, agriculture and ecosystems. Relatively less studied than other monsoons, the North and South American monsoons’ variability at intraseasonal to interannual and interdecadal variability time scales remains elusive, not least because of the scarcity of observations. Furthermore, as global climate warms, an understanding of variability and extremes is an even more pressing challenge. This session invites papers on all aspects of variability of the North and South American monsoons, and the impact of climate change on such variability. Papers discussing observed variability, impacts of climate change, land-atmosphere interactions, moisture sources, predictability of the monsoon at intraseasonal to interannual and interdecadal time scales, model intercomparison and projections of future changes in monsoon variability due to global warming are especially welcome.
