Polar vortex is the name given to thestrong currents of wind formed by low pressurethat occurs in the Arctic and Antarctic regions. ... The air is often contained by a strong jet of west-to-east moving winds that act like a wall, containing the cold air. What do you do in a polar ...
The last time similarconditions were observed was in spring 2011.While a hole over the Arctic is a rare event, the much larger hole in the ozone layerover the Antarctic has been a major cause for concern for more than four decades. Theproduction of ozone-depleting chemicals has been ...
This swirling mass of air above the Arctic can grow and bend, pushing blasts of frigid air south.
Did you know that the coldest place in the world (on average) is the East Antarctic Plateau? This frozen ice ridge between the summits of Dome Fuji and Dome Argus has seen temperatures of -148 degrees Fahrenheit. Now that’s cold weather!
While a hole over the Arctic is a rare event, the much larger hole in the ozone layer over the Antarctic has been a major cause for concern for more than four decades. The production of ozone-depleting chemicals has been dramatically reduced, under the 1987 Montreal Protocol 蒙特利尔协议),bu...
How cold is a polar vortex? How cold is the Antarctic Ocean? What is the climate in the Arctic region? What is the average climate in Antarctica? What is the temperature of the Mediterranean Sea? What is the temperature at sea level?
000 years. These polar regions are each the size of Asia, containing enormous amounts of cold, dense air that is held in check by the jet stream. However, the specific physical mechanism within these regions that responds to insolation changes over extended periods to cause ice ...
polar vortexcircular vortexThe importance of horizontal and vertical advection of temperature for the Antarctic major stratospheric warming in September 2002 has been investigated, by applying the thermodynamic energy equation to ECMWF temperature and wind data. The analysis, which is carried out for the...
the austral summer3,8. Although the ozone depletion in the Arctic region has been less pronounced compared to the Antarctic region in the past 30 years, it is still associated with the strengthening of the polar vortex and a notable and persistent shift in the tropospheric circulation towards a...
The smaller-sized Antarctic ozone hole of 2002 is approximately equal to that of 1988 when a strong sudden stratospheric warming occurred. If only the destruction of ozone by chlorofluorocarbons resulted in the delayed sudden stratospheric warmings in Antarctica, then the early sudden stratospheric ...
