time. With surface flooding on the cards and the potential for rivers to burst their banks, Karen logs on to the Met Office website to double-check warnings she’s specified for nominated colleagues. All correct. Next, Karen receives a call from the dedicated Met Office Public Weather Service Advisor

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

Our bespoke weather services to the water industry address changes in demand, impacts on water quality in the purification process and bursts on distribution.

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