Session 1

Clouds, Circulation and Climate Sensitivity

 

Session Description:

Arguably the climate systems most important constituent, atmospheric water remains, paradoxically, poorly quantified.  Water in all its phases both responds to and organizes circulations, setting the amplitude of the climate response to forcing, but also the pattern of regional circulation changes.  Experts in remote sensing, surface observations, and climate model evaluation review the prospects for advancing understanding of the Earth system through a renewed observational focus on atmospheric water and its interplay with winds.
