Abstract
Ten single column models (SCMs) from eight groups are used to simulate
a nocturnal non-precipitating marine stratocumulus-topped mixed layer
as part of an intercomparison organized by Global Energy and Water
Cycle Experiment Cloud System Study, Working Group 1. The case is
idealized from observations from Dynamics and Chemistry of Marine
Stratocumulus II, Research Flight 1. SCM simulations with operational
resolution are supplemented by high resolution simulations and
compared with observations and large-eddy simulations. All
participating SCMs are able to maintain a mixed cloud-topped layer
with some degree of decoupling and a sharp inversion, and produce
entrainment rates broadly consistent with observations, but the liquid
water paths vary by a factor of 10 after only one hour of simulation
at both high and operational resolution. Sensitivity tests show
insensitivity to activation of precipitation and shallow convection
schemes in most models, as one would observationally expect for this
case.
