The NCAS Weather directorate conducts research on dynamical and physical processes in the atmosphere on the local and regional scale. This involves atmospheric flows ranging from fine scale turbulence up to mesoscale weather systems. the work is organised in two broad themes: urban meteorology, pollution stransport and air quality; and convective processes and severe weather.

The research exploits state-of-the-art observations made in collaboration with NCAS technology divisions. It makes considerable use of high resolution models for data interpretation and improvement of physical understanding, and contributes to the development of such models. The results contribute to improved weather prediction, particularly concerning small scale processes and severe weather; to better representation of small scale processes in global climate models; and better forecasts of air quality.
