'Unusual' British weather could be down to 'warmer Atlantic'

The UK's recent run of damp summers could be down to a cyclical warming of the Atlantic Ocean, scientists and meteorologists have said.
At a gathering at the Met Office in Exeter, they suggested a 10- to 20-year pattern of Atlantic warming was shifting the jet stream, leading to washouts in six of the last seven summers.
The researchers said the location of the fast moving winds of the jet stream was critical to the UK's weather.
