Abstract: A mesoscale model is used to simulate the diurnal evolution of sea fog off the northeast Scottish coast observed on 27 April 1984. It is shown that the accuracy of the early part of the forecast is very dependent on the ...

Abstract: A new turbulent mixing scheme, described in Part I of this paper, is tested in the climate and mesoscale configurations of the U.K. Met. Office?s Unified Model (UM). In climate configuration, the scheme is implemented along ...

Abstract: A new boundary layer turbulent mixing scheme has been developed for use in the UKMO weather forecasting and climate prediction models. This includes a representation of nonlocal mixing (driven by both surface fluxes and ...
