When the polar vortex is strong, the mid-latitude Westerlies (winds at the surface level between 30° and 60° latitude from the west) increase in strength and are persistent. When the polar vortex is weak, high-pressure zones of the mid-latitudes may push poleward, moving the polar vortex, jet stream, and polar front equatorward. The jet ...
The northern hemisphere and the southern hemisphere each have a polar jet around their respective polar vortex at around 30,000 ft (5.7 mi; 9.1 km) above sea level and typically travelling at around 110 mph (180 km/h) although often considerably faster. [2] Closer to the equator and somewhat higher and somewhat weaker is a subtropical jet. [2]
The polar vortex is a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole (as its name suggests). The polar vortex is a gigantic, circular area ...
The polar vortex is a large area of low-pressure and cold air surrounding both of the Earth’s poles, according to the weather service. It always exists near the poles.
The polar vortex is a large storm that dwells in the middle and upper parts of the atmosphere and typically resides around the Arctic Circle.
The south polar vortex was imaged again in 2013 and it was determined that the vortex forms higher up in the atmosphere than previously thought. The hazy atmosphere that Titan has leaves the moon unilluminated in the Sun's rays but the image of the vortex showed a bright spot on the south pole.
The polar vortex is cyclical high-altitude winds that blow counterclockwise around the pole experiencing winter in the stratosphere, the next layer of atmosphere above the lowest, the troposphere ...
AccuWeather forecasters break down the science behind the polar vortex and how it can influence the weather for locations thousands of miles away. While the name for this phenomenon may sound ...
