 | Our Atmospheric
model of Intermediate complexity (AIM) is being used in
coupled integrations - see here.
|
| We are comparing the dynamical core of our atmospheric
model with the 'benchmark' calculation proposed by Held and
Suarez, 1994, in which temperatures are relaxed to a
prescribed 'radiative-convective' equilibrium temperature
which depends on latitude and pressure and a Rayleigh
damping of the low-level winds is used to prepresent
boundary-layer processes.
The figures below show zonal-mean zonal winds
and potential temperature averaged over 6 months after 3 years
of integration. Here twenty vertical levels were used, equally
spaced in pressure intervals - the bottom is flat.
Close agreement with the Held spectral model
and the Suarez finite-difference model is found, suggesting
that the idea of exploting atmosphere-ocean isomorphisms and
the same kernel code to drive both fluids is worthy of
pursuit. |

Our high-end atmospheric model, incorporating Kerry
Emanuel's convection scheme, is being used to study moist
baroclinic instability on the sphere. The model has 40
vertical levels and 150 km horizontal resolution. |
