Wednesday morning will begin with locally heavy rain moving southeast across parts of England and Wales, accompanied by an area of showers pushing southeast. By mid-morning, the rain will clear the far southeast, leaving behind variable cloud cover and scattered showers. Temperatures will be around

Cyril leads a team improving the way that clouds and radiation are represented in weather forecasts and climate simulations.

Top level summary of PS43 PS43 introduces atmospheric physics upgrades to both the global and regional NWP models. In the global model there are changes to improve boundary-layer processes, the representation of cloud, radiation, warm rain microphysics, and deep convection, whilst in the regional

Richard studies cloud microphysics focusing on ice nucleation and ice-phase evolution, using data obtained from the FAAM BAe146 research aircraft.

Amanda uses surface and balloon-borne instruments to observe and study cloud and radiation processes, so as to improve their representation in Numerical Weather Prediction forecast models.

Areas of expertise Cloud microphysics modelling and observation. Instrumentation for boundary-layer and cloud studies. Publications by Amanda Kerr-Munslow Current activities Amanda is responsible for the use and maintenance of ground based and balloon-borne instruments used for cloud and fog

. As it rises and cools, water vapour condenses to form clouds and perhaps precipitation. Consequently, the weather in a depression is often cloudy, wet and windy (with winds blowing in an anticlockwise direction around the depression). There are usually frontal systems associated with depressions. Figure

temperatures are expected to reach between 27°C and 29°C quite widely, with some locations in southern England potentially peaking at 30°C or 31°C. Further north, conditions will remain largely dry and warm, although there will be more cloud, particularly along North Sea coasts. A few isolated showers

radiation signature emitted by the atmosphere or surface. It uses the fact that the radiation reaching the satellite will vary from wavelength to wavelength depending upon the temperature structure of the intervening atmosphere and the presence of any absorbing gases and clouds. The method

the key feedback mechanisms relevant to improved simulations of present-day climate and climate change. Key aims Improve our understanding of the physical basis for cloud and water vapour feedbacks. Improve the representation of clouds, water vapour and the Earth's radiation budget in the Met Office
