A24D:
Monsoons of the Americas, Teleconnections, and the Subseasonal to Decadal Earth System Prediction Capability II

Submit an Abstract to this Session



Session ID#: 33169

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 American monsoons’ variability at subseasonal to interannual and interdecadal variability time scales remains elusive. Furthermore, as global climate warms, an understanding of variability and extremes is an even more pressing challenge.
