Themed Joint Session 1 Role of the Stratosphere in Climate Variability, Change, and Prediction—Part I

Monday, 7 January 2019: 2:00 PM-4:00 PM
North 128AB (Phoenix Convention Center - West and North Buildings)
Hosts: (Joint between the 32nd Conference on Climate Variability and Change; and the 20th Conference on Middle Atmosphere )
Isla R. Simpson, NCAR, Boulder, CO and Andrea L. Lang, University at Albany, SUNY, Department of Atmospheric and Environmental Sciences, Albany, NY

In this session we will examine the role of the stratosphere in climate variability, change, and prediction from the tropics to the extratropics.  Increasingly, stratospheric processes have been found to increase predictive skill of tropospheric climate on S2S and longer timescales.  Additionally, we will consider the role of the stratosphere on climate variability from seasonal to decadal timescales as well as the stratosphere's role in long term climate change.  We are also interested in studies that examine how stratospheric processes might be better simulated to enhance predictability.
