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

Charlie specializes in modelling the dispersion of volcanic eruption clouds using the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME).

Areas of Expertise Volcanic cloud transport and dispersion   Current Activities Charlie is working in the Volcanic and Chemical Dispersion team of the Atmospheric Dispersion and Air Quality (ADAQ) group within Weather Science. Charlie is currently working on the development of resuspended volcanic

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

In the atmosphere, we can see liquid water droplets in clouds and we can also see ice crystals as clouds too, but these are usually much higher up. What is the water cycle? The water cycle is the process by which water is continuously transferred between the surface of the earth and the atmosphere
