SSW Event Tracking

SSW Event Tracking ℹ️

This chart shows the zonal wind speeds at the 10 hPa level in the stratosphere above the Arctic. The data is used to track Sudden Stratospheric Warming (SSW) events, which occur when these wind patterns reverse or weaken significantly. SSW events can lead to major disruptions in the polar vortex, often resulting in unusual weather patterns, such as cold air outbreaks in the mid-latitudes.
