- Abstract:
- The aim of this research is to provide improved quantitative estimates of the rate at which frontal regions in weather systems transport polluted air from the boundary layer to the free troposphere. Modelling studies performed using typical mesoscale to regional-scale resolution cannot resolve certain frontal mixing processes which are clearly visible in high resolution radar observations; namely multiple shear layers and large-amplitude Kelvin-Helmholtz billows. We propose to perform very high-resolution (of order 2 km by 90 vertical levels) model simulations of frontal cases using the new dynamics (nonhydrostatic) Met Office model. The dynamical representation of these mixing processes and the transport and mixing of passive tracers in the model will be evaluated using observations. The climatological impact of these individual fronts will be determined using a climatological frontal database.
