, and improvements to the way mixing is represented in the boundary layer under certain cloud regimes has corrected a long-standing problem of unrealistic temperature profiles. In the tropics and sub-tropics, convection has more realistic structure and spurious light rain/drizzle is reduced

restrictions in coastal waters; such as in the Moray Firth and Firth of Forth during prevailing westerly wind conditions. The Pentland Firth is also resolved by multiple cells in the model, although the addition of current information would be needed in order to properly represent wave growth and dissipation

autumn. This seasonality is caused by the amount of sunlight reaching the polar regions of the Earth which are virtually dark for 4 months over winter and light throughout the day for much of the summer. During the winter, in the absence of any sunlight, the sea ice insulates the ocean from

day – and a simple traffic light system was developed to signify potential hazards. Supported by: Fund Manager: Spreading the message Developing the forecasts was one thing, but getting them out to remote communities across a vast geographical area was another. To be effective, it was crucial

and rain will begin to approach the far northwest later in the night. Further south, areas such as Wales, southwest England, and the Midlands may see light rain or drizzle under low cloud, while other regions remain dry with variable cloud cover. It will be a mild night for most. Outlook for Saturday
