HCTN 28: The Representation of Water Vapour and Its Dependence on Vertical Resolution in the Hadley Centre Climate Model

Overview Simulations of the Hadley Centre Atmospheric climate Model version 3, HadAM3, are used to investigate the impact of increasing vertical resolution on simulated climate. In particular, improvements in the representation of water vapour and temperature in the upper troposphere and lower stratosphere are identified with more accurate advection. Degradations in some aspects of the simulation in the tropics are identified with undesirable resolution dependencies in the physical parametrizations. The overall improvements in the water vapour and temperature distribution lead to improvements in the clear sky longwave radiative fluxes with higher vertical resolution.
