abstract = "Advances in computer power have made it possible to increase the
spatial resolution of regional numerical models to a scale
encompassing larger convective elements of less than 5 km in size.
One goal of high resolution is to begin to resolve convective
processes, and therefore it is necessary to evaluate the realism
of convective clouds resolved explicitly at this resolution. This
paper presents a method that is based on satellite comparisons to
examine the simulation of continental tropical convection over
Africa, in a high-resolution integration of the Met Office Unified
Model (UK UM), developed under the Cascade project. The spatial
resolution of these simulations is 1.5 km, the temporal resolution
is 15 min, and the convection is resolved explicitly. The Spinning
Enhanced Visible and Infrared Imager (SEVIRI) radiometer
measurements were simulated by the Radiative Transfer for the
Television and Infrared Observation Satellite (TIROS) Operational
Vertical Sounder (RTTOV) model, and then a comparison between the
simulations and real SEVIRI measurements was performed. The
analysis using the presented method shows that the UK UM can
represent tropical convection dynamics realistically. However, an
error has been found in the high-level humidity distribution,
which is characterized by strong humidity gradients. A key point
of this paper is to present a method for establishing the
credibility of a convection-permitting model by direct comparison
with satellite data.",
