-colour image highlights where snow is lying on the ground. They are created using five channels in the near-infra-red part of the spectrum so things look a little different to what the human eye would see. Snow can be easily differentiated from the white cloud as it now appears in a bright orange

was northeasterly Force 45. 3. From the evening of the 18th the overcast cloud thickened and the height of its base was under 500 feet throughout the 19th till late in the evening of that day. Winds were Northeasterly Force but increased to Force 6 and .5 7 during the afternoon and evening of the 19th

The weather is set to bring a largely dry and settled spell midweek, with a mix of sunshine, cloud, and cooler conditions in some areas.

Wednesday will see most parts of the country enjoying fine and dry weather, with variable cloud cover and sunny intervals. However, the sunshine may appear hazy at times due to patches of medium and high-level cloud. The far north and parts of the east and southeast could see more persistent cloud

of maritime and continental influences; the air is likely to be warm and predominantly dry, generating fair weather clouds but also some lower cloud bases in moister air to the west. The presence of an upper cold front to the east of England complicates the picture somewhat and will need investigating. What

Its primary uses are for the modelling of clouds and atmospheric flows. The results of these simulations help us to develop the physics parametrizations in the Unified Model. LEM use and collaboration A number of process studies have been carried out using the LEM, including those within the GASS

% of average. 1st to 7th Central and northern parts saw mist, fog and frost on the 1st, the fog slow to clear in some spots, especially in the east, but southern and north-western counties became sunny. The north-west began the 2nd clear and frosty, but low cloud, mist and fog affected most other places

of the Great Lakes. The ensuing warming of the atmosphere at low levels causes de-stabilisation, producing rising air parcels. These in turn develop into narrow bands of convective cloud, oriented along the wind flow, that can rapidly deposit large amounts of snow downwind. The above images show data from

) recording 12.0 hours of sunshine, but there were isolated showers in the north-east at first, and later in some southern and central parts where cloud increased. Many areas began sunny on the 2nd, with more cloud elsewhere, most notably central counties, with showers in places, tending to drift
