. The lightning information from LEELA is delivered in Met Office bulletins, 24 hours a day, 365 days a year. LEELA is more sensitive to cloud to ground lightning than in-cloud lightning and does not discriminate between these different forms of lightning in its bulletins. Resolution: Although LEELA

). 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

November due to the ongoing unsettled weather, with groundwater flooding an issue in parts of Dorset, and many rivers having burst their banks. Storm Debi on 13th brought the strongest winds to coastal areas of Northern Ireland and north-west England. A number of roads in Northern Ireland were blocked

stations on land, ships and balloon ascents. The first satellites which observed the atmosphere were the TIROS class of satellite which imaged the Earth from a low Earth orbit showing the position of clouds in rather fuzzy images. TIROS-1 was launched in 1960 and was the first dedicated
