the ground, which in turn heats the air above, and this warm air then rises. As it rises, it cools and expands, forming clouds when the air has cooled to the dew point and the moisture (if present) condenses. These ‘fair weather clouds’, with flat bottoms and fluffy white tops form a clear marker

a host of advances (as detailed in a peer reviewed paper) which deliver a marked improvement compared to previous models. For example, while the Met Office’s highly regarded previous generation model HadGEM2-ES is considered a world leader in its representation of clouds, the new models include

Through Friday high pressure will remain dominant across the UK, bringing another day of settled weather with plenty of warm sunshine across the country. It will be a warmer day than yesterday due to a reduction in cloud cover, especially in the far east and northeast where there will be less

Starting off on Tuesday morning, the Northern Isles will see cloud and light rain or drizzle by day, with some scattered showers in Caithness in the afternoon. Elsewhere we'll see dry and sunny conditions, with much warmer temperatures. Inland areas will see temperatures mostly between 22-24°C

areas, but cloud in the south-west spread to other areas through the afternoon. The 2nd saw some brightness in the south, but other areas were cloudy, with patchy rain or drizzle over the north at times. The 3rd was again generally cloudy and mild, but with a few brighter spells, and also patchy
