Numerical Modelling
The group in the Chemistry Department has a very active research program into all aspects of atmospheric chemistry. There a modelling studies of stratospheric and tropospheric chemistry, using 1D, 2D and 3D models. The group also builds its own instruments for observations of chemical constituents in the atmosphere. There is also research being carried out into the kinetics of reactions important for atmospheric chemistry. In the Department of Applied Mathematics and Theoretical Physics, scientists are engaged in studying fundamental dynamical processes; for example mixing processes in atmosphere and the development of new gravity wave parametrizations for atmospheric models. In the Dept. of Geography, research is being carried out into small scale processes such as mixing within plumes and application to volcanic eruptions.

Our group uses state of the art computer models to study the role chemical species have on our atmosphere. We use CTM's (p-TOMCAT) and GCM's (Unified Model & UKCA).

Prof. Peter Haynes (Mathematics)
Peter Haynes' research focusses on the large-scale fluid dynamics of atmosphere and ocean, and related topics, particularly in climate science. In fluid dynamics he is interested in wave propagation and breaking and its implication for the background flow, and in transport and mixing of trace species, including reacting chemical and biological species. These topics are relevant to both atmosphere and ocean. In atmospheric science, he is interested in the dynamics of the global circulation, in interactions between dynamics, chemistry and radiation, and in the various physical and dynamical processes controlling the distributions of chemical species, including water vapour.

Prof. Hans Graf (Geography)
My research has always been a mixture of modelling and data analysis, examining all time and space scales of climate variations, from cloud microphysics up to global general circulation. Recently I have concentrated on processes of relevance to climate change, during the last years more focussed on physico-chemical aspects of climate change, particularly aerosols, stratospheric ozone, and fundamental modes of general circulation. Further I am involved in volcano and biomass burning plume modelling. A relatively new field is the modelling and parameterisation of convective clouds for use in non-cloud resolving models, which allows for consideration of chemistry-aerosol-microphysics processes.

My research activities and interests include:
- development of atmospheric models from local to global scales
- modelling of convective clouds and plumes
- role of convection in the climate system, understanding of the hydrological cycle in present and future climate
- understanding of the role of aerosols in present and future climate, impact of aerosols on dynamical and microphysical processes
