WHY IS IT SO UNSETTLED?**
**Since the start of December the UK has seen a prolonged period of particularly unsettled weather, with a series of storms tracking in off the Atlantic bringing strong winds and heavy rain. It is winter of course so it isn't unusual to see stormy, wet conditions. This is because we see a particularly big difference in temperature between the cold air in the Arctic and the warm air in the tropics at this time of year.This contrast in temperatures means we see a strong jet stream, which is a narrow band of fast moving winds high up in the atmosphere.
The jet stream can guide storms as they come across the Atlantic, and it has been sitting in the right place to bring those storms to the UK over the past few weeks.
There’s also a close link between the jet stream and storms. The jet stream can add to the strength of storms, but then storms can also increase the strength of the jet stream. This positive feedback means storms can often cluster together over a period of time.
However even accounting for the fact that it’s winter, the jet stream has been particularly strong over the past few weeks and it looks like it will remain settled over the next week too.
