If the model is configured to
simulate small clouds or turbulence with a grid spacings of 100 m or less we usually refer to this as a «large eddy simulation» (LES).

The
simulated image at left shows how the
smaller particle size in Venusian
cloud tops (compared to a typical 10 to 40 micrometers in terrestrial ones) causes the colored fringes to spread further apart than they would appear on Earth.
Earth system models integrate atmospheric, oceanic, chemical, and biological processes, many of which are too complex or occur at scales too
small to
simulate directly (e.g., formation of individual
clouds).
Aerosols and
cloud processes vary on much
smaller time and space scales than climate models can
simulate.
Climate models can not
simulate clouds explicitly because their dynamic scales (10 - 100 m) are much
smaller than typical length scales of climate model grid boxes (25 - 100 km).
This discrepancy is associated with
simulated increases in daily maximum temperature being larger than observed, and could be associated with
simulated increases in
cloud cover being
smaller than observed (Braganza et al., 2004; see Section 3.4.3.1 for observations), a result supported by other analyses (Dai et al., 1999; Stone and Weaver, 2002, 2003).
Earth system models integrate atmospheric, oceanic, chemical, and biological processes, many of which are too complex or occur at scales too
small to
simulate directly (e.g., formation of individual
clouds).
We use the large - eddy simulation code PyCLES to
simulate the dynamics of
clouds and boundary layers, to elucidate their response to climate changes, and to develop closure schemes for representing their
smaller - scale dynamics in larger - scale climate and weather forecasting models.
Radiative convective models in
small domains, no matter what the resolution, do not
simulate the spatial inhomogeneities and convective structures that occur in the tropics, and should not be thought of as providing quantitative simulations of tropically - averaged
clouds (or relative humidity for that matter).
