| Four groups, each work on different
aspects of atmospheric physics which are parametrized in our NWP
and climate models. The groups work closely together, and with observational
research groups in the Met Office and in several UK universities,
to improve our understanding of the processes and hence improve
their representation in the operational models. |

This group works on simulation and parametrization of turbulent transports
in the atmospheric boundary layer: that portion of the atmosphere
which 'feels' the presence of the earth's surface. The group is well
known for its work on Large Eddy Simulation (LES) which is an important
tool for turbulence modelling.

This group works on the representation of cloud microphysical
processes and radiative transfer in the atmosphere. Cloud processes
are very complex and this is an area in which observational evaluation
is an important input to our work. We have a state-of-the-art
radiation code which has been validated against detailed line-by-line
codes.

This group uses high-resolution simulations of ensembles of convective
clouds to improve our understanding and parametrization of convective
transports in the atmosphere. Tropical convection is a particularly
important and challenging aspect of the subject, as is mesoscale organisation
of convection. The group is active in international research collaborations.

This group uses high-resolution simulations of flow over hills and
mountains to improve our understanding of the effects of the orography
on the flow. For parametrization purposes we need to represent flow
blocking and drag effects, and the generation of gravity waves which
transport momentum. We are also interested in the prediction of severe
weather associated with mountains, such as downslope winds, lee wave
rotors, and heavy rain.
