in the first two weeks roughly 2°C below average. The cool start to the month was due to northerly and northwesterly winds bringing cold Arctic air across the UK. A low pressure centre developed over Scandinavia in the second week of June, pushing further cold air from the north across the UK. Frontal

A lidar measures backscattered light from atmospheric targets e.g. aerosols including volcanic ash and Saharan dust, water droplets and ice crystals, using

Lead author and Met Office climate scientist, Mike Kendon, said: “Our new analysis of these observations really shines a light on the fastest changing aspects of our weather as a consequence of climate change. Long term averages can be difficult

The Pentland Firth is also resolved by multiple cells in the model, although the addition of current information would be needed in order to properly represent wave growth and dissipation
