Sensitivity of the Hadley circulation to parameterization of upper tropospheric ice clouds using a global cloud-system resolving model We examined the relationship between upper tropospheric ice-cloud properties and the Hadley circulation intensity through parameter sensitivity studies of global cloud-system resolving simulations with explicit cloud microphysics. Experiments under a perpetual July condition were performed by changing parameters in the boundary layer and cloud microphysics schemes, with a mesh size of approximately 14 km. One additional experiment with a mesh size of approximately 7 km was also conducted. These experiments produced a variety of upper cloud areas and out-going longwave radiation (OLR) distributions. We found that as the upper cloud area increased, the total precipitation decreased and the intensity of the Hadley circulation weakened because of energy balance constraints. Interestingly, the net ice water path was not correlated with the upper ice cloud areas or OLR, indicating that the spatial coverage of upper ice clouds, rather than the total ice water content, was the key factor in the radiation budget. We will also discuss key factors of cloud microphysics on precipitation efficiency and climate sensitivity.
