Mystery as stratospheric wind patterns change for first time in 60 years of observations 

Lowest solar cycle in a hundred years, 60 odd years of observations….must be climate change *palms forehead*

Another climate mystery – this time the QBO – for scientists to get their teeth into, as the Mail Online reports.

For more than 60 years, atmospheric scientists have observed the consistent behaviour of a wind pattern known as the ‘quasi-biennial oscillation’ – a phenomenon that repeats every 28 months. But in late 2015, the long-reliable pattern suddenly changed. 

The winds have since returned to their normal course, and while no immediate effects were detected, astronomers are working to understand if this was just a one-time ‘black swan’ event, or a ‘canary in the coal mine’ signalling unseen conditions.

  1. Very interesting implications for winter – though QBO only a small piece of the puzzle. Not yet had the chance to crunch any numbers but I would guess that this winter will at last bring one snowy spell for the SE, the best in 4 years?
