The polar vortex is expected to strengthen in the short term and maintain warmer conditions in eastern North America for the foreseeable future, according to Atmospheric and Environmental Research.
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.
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 polar vortex as captured by the Atmospheric infrared sounder. Normally, the Northern Hemisphere jet stream travels fast enough to keep the concentration of Arctic air known as the "polar vortex" stationary in the stratosphere over the North Pole.
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 ...
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).
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 ...
