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

widely from late morning onwards. After another bright, cold start on the 2nd, with isolated showers over northern counties and locally along the south coast, cloud increased by midday with showers occurring quite widely. All areas were cloudy and windy on the 3rd, with rain already in the west

). Overleaf are a series of plots showing the Gerrity Skill Score in relation to the agreed performance measure for forecast Cloud Base and Visibility at airports in receipt of 9, 24 and 30 hr TAFs. The values obtained range from 0 to 1, where 1 indicates perfect forecasts every time, the value we aspire

A north-south split in conditions is expected across the UK on Thursday. The southern half of the country will enjoy a settled and dry day, with rather warm temperatures and periods of cloud. Maximum temperatures are forecast to reach 25-26°C in southeast England, remaining slightly above average

some locations may not fall below 18-20°C. Outlook for Friday Friday will continue the trend of warm and settled weather. Most areas will remain dry with sunny or clear spells, although medium to high-level cloud may persist for a time, particularly during the morning, reducing solar input

Saturday will begin with low cloud lingering across central and eastern areas, but this will lift and break through the morning, giving way to increasing amounts of sunshine by the afternoon. Elsewhere, conditions will be mainly sunny throughout the day. Temperatures will be very warm in the west
