Satellite image of an upper tropospheric cyclonic vortex in the western North Pacific. An upper tropospheric cyclonic vortex is a vortex, or a circulation with a definable center, that usually moves slowly from east-northeast to west-southwest and is prevalent across Northern Hemisphere's warm season.
The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct phenomena that have different sizes, structures, seasonal cycles, and impacts on weather.
Map of Monday highs and wind chills On Monday, the polar vortex will reach the Deep South, with temperatures down to the freezing point of 32 degrees Fahrenheit in Atlanta. Wind chills will be in ...
Editor's Note for Sat. Jan. 18: A polar vortex is set to impact much of the US. Click here for the latest update. A polar vortex is forecasted to blanket most of the continental United States in ...
Image of an upper tropospheric cyclonic vortex in the western North Pacific, a cold-core low. A cold-core low, also known as an upper level low or cold-core cyclone, is a cyclone aloft which has an associated cold pool of air residing at high altitude within the Earth's troposphere, without a frontal structure.
During the 2014 January polar vortex, more than 20 people across the country died from the cold as places like Georgia — which rarely see serious cold — dealt with lows under 10 degrees ...
A tropical upper tropospheric trough (TUTT), also known as the mid-oceanic trough, [1] is a trough situated in the upper-level (at about 200 hPa) tropics. Its formation is usually caused by the intrusion of energy and wind from the mid-latitudes into the tropics. It can also develop from the inverted trough adjacent to an upper level anticyclone.
Brutal winters may be in store for the portions of North America as the polar vortex continues to weaken and shifts, according to a new study. Weakening polar vortex may yield longer, harsher ...
