Episode 6 - The Beast From The East

We got together to record a quick podcast to discuss "The Beast From The East" a sudden cold snap that's due to hit the UK in a few days (Feb 2018).

What is this kind of weather event called, what causes it and what kind of weather conditions can we expect?

Hope you  enjoy the show!

Sudden Stratospheric Warming event

A Sudden Stratospheric Warming (SSW) event has taken place, resulting in the split of polar vortex in two vortices which may impact our weather later this month (there is a lag time between an SSW and the impact it has on UK weather).

A SSW of the atmosphere refers to a rapid rise in temperatures in the stratosphere (which is found at an altitude of 10 km to 50 km) when the temperature can rise by up to 50°C over a couple of days – and this often leads to cold conditions across the UK.
