  on the 2nd, but showers became more frequent in the north-east from early afternoon. Cloud, mist and fog with light rain spread across the south and parts of the Midlands on the 3rd, with sunshine and showers in the north, the showers turning thundery over the Pennines at times. High pressure then built

• Radiative transfer in the atmosphere

  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
