Early cloud and rain across northern Scotland will gradually become confined to Shetland, allowing for brighter spells to develop elsewhere in the north. However, much of the UK will see a band of cloud and rain moving eastwards through the day, with the heaviest and most persistent rain affecting

Anthony studies how electromagnetic radiation interacts with particulates suspended in the Earth's atmosphere with an emphasis on ice crystal clouds or cirrus.

Areas of expertise Electromagnetic and light scattering; Radiative transfer theory; Numerical methods; Cloudy satellite remote sensing; Cloud microphysics. Publications by Anthony Current activities Anthony is currently responsible for the development of models that predict ice crystal scattering

spells will break through, although a few showers are likely in the northwest. Elsewhere, much of central, southern, and eastern England, as well as the remainder of Wales, will experience variable and often large amounts of cloud. However, there will be some sunshine, particularly in eastern areas

were the 4th highest for August in a series from 1919, with 132% of average. 1st to 4th Cloud over the Midlands and south-east cleared away to leave sunshine for all for a time on the 1st, but cloud increased with rain, occasionally heavy, spreading from the west into central and northern areas from

Anglia died out by lunchtime, with the cloud thinning and breaking through the afternoon. Most areas were frosty early on the 8th, then mostly sunny for a time, but cloud soon increased from the west, with rain reaching the southwest by mid-morning making slow and erratic progress eastwards

of the properties of convective clouds have been made by international field studies, such BOMEX, RICO, TOGA-COARE and TWP-ICE.  But it is challenging to get enough detail from these data to study the small-scale processes often responsible for initiating convection.  Further insight can be gained

who adopt a more conservative approach. Unlike the SQI more than one category threshold is used by the GSS (see table 1). The Met Office assess all the TAF cloud base and visibility categories defined by ICAO. At the time of writing, the following categories are used for TAF assessment: Surface

) - - Integrated Diffuse Downward SW radiation kJ/m2 Hourly to T+360 (6) - - Instantaneous SW is the power (per unit area); integrated SW is the energy (per unit area) over the previous hour, commonly expressed as kWh (1kWh = 3600kJ) Cloud Cloud Amount < 200feet oktas Hourly to T+360 - - Low cloud amount
