Jet Stream Forecast

The Jet Stream is a river of fast moving air in excess of 100 miles per hour, at an altitude of 20,000 feet or more, flowing around the Earth from west to east. It can have a dramatic effect on the UK weather. The Jet Stream is affected by the El Niño Southern Oscillation, a cycle which can last between 2 to 7 years. The cycle alternates between El Niño years, when the Eastern Pacific Ocean (centred off the coast of Peru) is unusually warm and La Niña years, when the Eastern Pacific Ocean is cool. La Niña is linked to bad summers across Europe. Bad weather (Low Pressure) tends to be pushed north of the Jet Stream. Good weather (High Pressure) tends to be pushed south of the Jet Stream. If the Jet Stream flows north of the UK, expect good weather. If the Jet Stream flows south of the UK, expect bad weather.
