Extreme weather on a monthly or seasonal timescale is associated with persistent large-scale weather patterns.
For example, the unusually wet summers of 2007, 2008 and 2012 in the UK were associated with a similar Rossby wave pattern on the jet stream which was almost stationary over the UK.
A contrasting season was winter 2013/14 where the jet stream was directed at the UK and extreme seasonal rainfall resulted from a succession of weather systems hitting the UK.
In both examples, the persistence in the latitude of the jet stream is a key player.
This project aims to gain a theoretical understanding of the persistence of the jet stream, by looking at Rossby wave structures.
This could improve future prediction of extreme weather events.
