Prof. Reed contributed to a study led by Dr. Sandrine Bony from IPSL (Paris). The work published last month in the Proceedings of the National Academy of Sciences (PNAS) investigates what controls amount of deep convective clouds in a warming environment. The investigation of various model simulations demonstrates that as the climate warms, clouds rise while remaining at similar temperature. However, as the clouds rise they find themselves in a more stable upper atmosphere which reduces the convective outflow in these regions and decreases the anvil cloud fraction.
