Joint Session 48 Monsoons of the Americas: Advancing Understanding and Improving Prediction through Observations and Models

Thursday, 11 January 2018: 8:30 AM-9:30 AM
Room 18A (ACC) (Austin, Texas)
Hosts: (Joint between the 32nd Conference on Hydrology; and the 31st Conference on Climate Variability and Change )
Francina Dominguez, Univ. of Illinois at Urbana−Champaign, Atmospheric Sciences, Urbana, IL; Ben Lintner, Rutgers, State Univ. of New Jersey, Environmental Sciences, New Brunswick, NJ and Yolande L. Serra, JISAO, Seattle, WA

The North and South American monsoons are of vital importance for regional water resources, agriculture and ecosystems. Observations and modeling are the cornerstones of research efforts aimed at improving our understanding of the intraseasonal to interannual variability of the American monsoons and will ultimately lead to improved prediction of these systems. In this session, we invite papers on all aspects of variability and predictability of the North and South American monsoons. Papers including the role of low-level jets and associated transports of water vapor, subseasonal to seasonal (S2S) prediction, the role of land surface processes in the evolution of the American monsoons, mechanisms for the influence of MJO on monsoonal variability, interhemispheric effects, observational campaigns, and modeling efforts are especially welcome.
