ISSI International Team on Mesoscale Patterns of Cloudiness and Humidity in the Trades

The aim of the International Team will be to advance understanding of what controls the cloud amount in the trades and patterns of convection in the broader tropics. Our Study Project will link existing and forthcoming satellite measurements to past, ongoing and planned field and simulation studies of clouds and mesoscale circulations in the broader tropics. Our project is motivated by the WCRP Grand Science Challenge Clouds, Circulation and Climate Sensitivity, the 2014 EUMETSAT Climate Symposium, and an ISSI Workshop in early 2016 on Shallow clouds and water vapor, circulation and climate sensitivity. With increasing specificity each of these activities pointed out the need to better understand, model and observe how water and circulations interact in the lower troposphere.
