Since 2007, and particularly in 2012 and early 2013, the jet stream has been at an abnormally low latitude across the UK, lying closer to the English Channel, around 50°N rather than its more usual north of Scotland latitude of around 60°N. However, between 1979 and 2001, the average position of the jet stream moved northward at a rate of 2 kilometers per year across the Northern Hemisphere.
