from fog persisting on some eastern coasts, with 15.8 hours of sunshine at Whitby (North Yorkshire). Most places started fine on the 2nd, but showers spread from the south-west, initially with isolated thunderstorms, reaching central and northwestern parts by early evening, while low cloud off

is cloud free and surface features such as coastlines, the snow-covered Alps and variations in the Northern Sahara desert surface are clearly visible. Geostationary satellites orbit at around 36,000 km above the Earth's surface and have an orbital period of one day, meaning they remain at a fixed

The representation of solar and infra-red radiation, and its interaction with clouds in our numerical models.

Various radiative processes occur in the atmosphere: gases, aerosols, cloud droplets and ice crystals absorb radiation and emit thermal radiation. Aerosols, cloud particles and air molecules scatter radiation. The surface absorbs, reflects and emits radiation. The radiative properties

Tuesday will bring a continuation of changeable conditions across western parts of the UK, with cloud and outbreaks of rain or drizzle moving eastwards through the morning. The heaviest rainfall is expected over west-facing high ground, particularly across Wales, northern England, and southwest

, it will be a largely dry day with variable cloud and sunny intervals. The best of the sunshine will be across southern, central and eastern England, where it will feel very warm, with temperatures reaching 27–28°C in places. It will be warm across much of the country, away from the northwest

not routinely measured but important for model process understanding. Areas of key interest Measure updrafts, turbulence and dynamical structures in convective clouds on fine scales. Understand effect of pre-convective environment on subsequent storm development. Interaction between boundary layer structures
