Session 6A Climate Change and the Large-scale Circulation

Tuesday, 12 January 2016: 3:30 PM-5:30 PM
La Nouvelle C ( New Orleans Ernest N. Morial Convention Center)
Host: 28th Conference on Climate Variability and Change
Kerry H. Cook, University of Texas, Geological Sciences, Austin, TX

GCM simulations of contemporary climate change under greenhouse gas forcing predict significant adjustments in the large-scale circulation, including the Hadley and Walker cells and the mid-latitude storm tracks. This session brings together modeling and observational studies of changes in the large-sale circulation in the 20th and 21st centuries to promote direct comparison between models and observations and an improved physical understanding.
