Several days into spring, wintry weather will linger as a cold air mass settles in. AccuWeather’s long-range experts say that ...

What is the polar vortex? One of the defining characteristics of SSW is the reversal of winds in the stratosphere, known as the stratosphere polar vortex. These winds circulate air high over the ...

Spring could be blighted with outbreaks of cold as temperatures plunge under the steer of wind changes in the stratosphere. For the past couple of weeks, experts have been watching a slowing of winds ...

From Paul Newman, GloPac co-project scientist: We were planning a test flight of the Global Hawk for Wednesday (March 10), but unfortunately the wind speeds are forecast to be too strong (with gusts ...

The Met Office has warned that colder weather is on the way thanks to 'rapidly weakening' winds in the polar vortex. Temperatures are set to drop across the UK following the warmest weekend of the ...

The phenomenon is characterised by a reversal of winds, the stratosphere polar vortex, high in the stratosphere. These winds are currently weakening rapidly. A weakening of the rapid westerly ...

This confusion has most likely come from the fact that the polar vortex - a fast wind very high in the atmosphere over the North Pole which keeps very cold air in place - is showing signs of ...

The temperature difference between the North Pole and the equator maintains the polar vortex's strong west-to-east winds over winter. However, sudden warming in the stratosphere can bring this ...
