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 ...
While the name for this phenomenon may sound intimidating to some, the polar vortex is actually a completely natural process t. Polar vortex. It's a phrase that becomes very popular has achieved ...
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 southern pole's cyclone-like storm is roughly the size of Europe. In addition, the southern polar vortex is constantly changing shape but the cause is still unknown. [4] In 1979, NASA's Pioneer Venus observed a double vortex cyclone at the north pole. There haven't been many more close-up observations of the north pole since Pioneer Venus. [5]
Polar vortex. It's a phrase that becomes very popular has achieved buzzword status and is often used frequently during the winter as the Northern Hemisphere endures its coldest months of the year ...
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 ...
The warming is preceded by a slowing then reversal of the westerly winds in the stratospheric polar vortex, commonly measured at 60 ° latitude at the 10 hPa level. [2] SSWs occur about six times per decade in the northern hemisphere (NH), [ 3 ] and about once every 20-30 years in the southern hemisphere (SH).
A snowstorm on February 3–4 brought 0.5 to 4 inches (1.3 to 10.2 cm) of snow to parts of Western Washington, including the Puget Sound region, after a winter without measurable snowfall. It was caused by cold air arriving from the north alongside a low-pressure system, dropping temperatures to the 30s and 40s.
