Colder than average conditions for the start of winter? | Official blog of the Met Office news team
Professor Adam Scaife, Head of long-range forecasting at the Met Office, said: “La Niña has a profound effect on weather across the globe and can have impacts extending as far as the UK.
“In late autumn and early winter La Niña tends to lead to high pressure developing in the mid-Atlantic, which stops Atlantic weather systems from delivering mild air to the UK, and therefore can allow cold conditions to intensify. However, in late winter La Niña tends to drive a strengthening of the jet stream towards the Arctic increasing storminess and heavy rainfall, while bringing milder conditions to our sector.”
