The latest edition of the Polar Vortex Blog has dropped and this week our experts explain how a major disruption of the polar vortex WAY up in the stratosphere can (but not always) impact the weather we feel at the surface. First it starts when a huge, planetary-scale wave in the atmosphere travels into the stratosphere -- which only occurs when the winds in the stratosphere are blowing west-to-east, as is generally the case during the northern hemispheric winter. It is complex, as there are a l

ℹ The jet stream is a narrow band of fast westerly flow in the upper troposphere that forms at the interface of air masses of different temperatures. This stream often meanders, as seen in the video, which shows the development of the jet stream over the next seven days over Europe. Such meandering affects the distribution of pressure formations in the atmosphere and the course of weather at the surface. ➡You can follow the development and forecast of the jet stream on Ventusky: https://www.vent
