The talk will introduce the UMUKCA composition-climate modelling system, a joint Met Office/NCAS development. It will discuss the models performance and introduce some sensitivity studies that reveal composition-climate interactions. I will show that the climate system (as represented by the model) can respond quite sensitively to small chemical perturbations in ozone. I will argue that some modelled circulation adjustments in response to a chemical change can occur in reality and will illustrate this point using MIPAS data. I will finish with an outlook towards smaller scale features that are currently not represented in this climate model set-up, even though they are potentially important for composition-climate interactions. My example will be the Borneo vortex (BV), an important source of extreme weather for Malaysia, and a factor in creating a dry, ozone rich layer in the upper troposphere/lower stratosphere.
