Weather phenomenon that led to ‘Beast from the East’ returning to UK this winter | EUROtoday
The UK might be dealing with one other chilly snap because the climate phenomenon that introduced in 2018’s ‘Beast from the East’ appears to be like set to have “significant implications” on the nation’s climate.
The Met Office stated “winter has arrived early across the UK, bringing cold Arctic air and a complex mix of weather hazards” after every week of ice and snow climate warnings throughout stretches of the UK.
Temperatures are set to extend this weekend as milder, extra unsettled, Atlantic-driven climate strikes in with cloud, rain and winds, however a sudden stratospheric warming (SSW) occasion within the subsequent week may see colder climate return within the subsequent two weeks.
A SSW entails a fast enhance in temperature within the stratosphere above the North Pole, typically resulting in a reversal of the stratospheric polar vortex winds, involving the fast descent of chilly air.
According to the forecaster, this will increase the probability of colder climate within the UK 10 to 14 days later by roughly 70 per cent. While not assured, meteorologists will probably be maintaining a detailed eye on the climate phenomenon that may result in a colder than common begin to winter.
“From the clash of Arctic and North African air masses to the impacts of heavy rain, flooding, and significant snow, the country is experiencing a wide range of conditions”, the forecaster reported. “Regional differences are stark, with some areas facing substantial snow while others enjoy sunny skies and frosty nights. The outlook remains uncertain, with the potential for further cold spells and unsettled weather as the season progresses. “
A SSW was the same weather phenomenon that led to the brutal ‘Beast from the East’ in 2018, which transported cold air from Siberia to Europe and heavy snowfall to Great Britain and Ireland. Temperatures plummeted across the country with lows of -14.7C recorded in Faversham, Kent, and Storm Emma brought 50 cm of snow in some elevated areas.
Temperatures dropped well below average for this time of the year across the country this week with wind chill making it feel even colder with “feels like” temperatures broadly at minus one or minus two levels. The Met Office recorded lows of -11.7C at Loch Glascarnoch on Thursday night time, the coldest night time of the season to date.
The current arctic air mass introduced snow to the UK this week as colleges had been pressured to shut throughout the nation, with yellow and amber ice and snow climate warnings issued for elements of the UK.
