  The representation of fog, cloud and rain processes in regional modelling is of fundamental importance for both NWP and climate, particularly at “convective” resolving scales. This session will include talks and discussion covering; fog and visibility,  microphysics (both cloud and aerosol), aerosol-cloud

to enable map functionality on a mobile phone. We have made the selecting of map layers easier and more intuitive than before. To find the forecast (mesoscale) map layers: open the map layer selector, and select 'FORECAST PRECIPITATION' or 'FORECAST VISIBILITY & CLOUD' and then make your choice

and increasingly warm weather to southern counties following foggy starts in places, but it was cloudier in the north and especially north-west, with some showery rain for the north-west on the 3rd and 4th, and more widespread cloud and light rain across the north on the 5th. The rain became heavier

was a quieter day with sunshine, starting frosty in the north with -3.5 °C recorded at Spadeadam and Bewcastle (both Cumbria), but the south-east was cloudy at first and cloud increased from the south-west during the day. 6th to 10th The 6th was dry and warm with some sunny intervals for most
