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

. 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

Peter currently works on the satellite-based (and ground-based) cloud products that are assimilated into the UK area model, UKV.

Areas of expertise Infrared satellite remote sensing Data assimilation Information content of observations Cloud products Current activities Peter’s work is on the surface-based ‘SurfaceCloud’ and satellite-based ‘GeoCloud’ products that are assimilated into the UKV model. These are both methods

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

and east, where temperatures could feel really quite warm for spring, pushing into the low 20s C - although even here there may be the odd shower, and persistent low cloud in coastal areas will keep them cooler.  Temperatures will be on the rise across many parts of the UK as we head towards
