Reconciling the Lack of a Robust Anvil Cloud Amount Response to Warming
Zachary McGraw, Blaž Gasparini, Wouter Mol +1
The stability-iris hypothesis proposes that tropical anvil cloud amount decreases with warming as anvils rise into environments of greater static stability. Here we show that there…

No Reduction of Tropical Convection with Warming Expected from Theory or Models
Zachary McGraw, Blaž Gasparini
Theoretical arguments have for decades anticipated substantial weakening of tropical convection as the surface warms, yet convection-resolving models show no robust change in colum…

Direct Radiative Impacts of Stratospheric Aerosols on the Tropical Troposphere: Clouds, Precipitation, and Circulation in Convection-Resolving and Global Simulations
Zachary McGraw, Lorenzo M. Polvani
A concern for stratospheric aerosol injection (SAI) is that stratospheric aerosols could inadvertently alter rain and winds through mechanisms independent of the intended surface c…
