Sentences with phrase «circumpolar vortex»

All these conditions combine to create a very powerful Circumpolar Vortex.

This is important because climate change is reflected most in these latitudes as the Circumpolar vortex shifts between Zonal and Meridional flow and the amplitude of the Rossby Waves vary.

Richard, as I pointed out elsewhere in this thread, the ozone hole facilitates cooling in the southern polar region while the circumpolar vortex block warm air advection from the north.

As a result a very strong wind, technically called the Circumpolar Vortex, but more commonly called the Jet Stream blows.

These Waves occur in the Circumpolar vortex, more commonly known as the Jet Stream, and determine the weather pattern in the middle latitudes between 30 and 65 ° of latitude.

The centre of each low pressure region is a persistent cyclone known as the circumpolar vortex.

It was also in a region, central Canada, were transition was important because it covers the annual shift of the Circumpolar Vortex (CV).

Similarly the climate is expected to be chaotic on longer timescales involving larger, more slowly changing processes such as the circumpolar vortex, major ocean currents and ice sheets.

It was determined that a major cause of changes in the size and extent of the Antarctic ozone hole are the intense wind patterns and circulations associated with the extensive Antarctic high - pressure zone and the surrounding wind pattern known as the Circumpolar Vortex.

They produced a static condition when the major natural mechanism causing ozone variation over Antarctica is an intense atmospheric circulation system associated with the Circumpolar Vortex.

The obtained results suggest an important part of the circumpolar vortex in the mechanism of solar - climate links.

Even in your home state, this «cold snap» from the descent of the circumpolar vortex will have home heating consequences.

For one thing there has been a noticeable expansion of the great belt of dry, high - altitude polar winds — the so - called circumpolar vortex — that sweep from west to east around the top and bottom of the world.»

Rather it claims that decreased ozone increases the velocity of the circumpolar vortex, thus breaking up pack ice and allowing more ice to form at the surface, thereby contributing to greater sea ice extent.

For reasons I do not fully understand, with global warming the circumpolar vortex has moved somewhat further south, exposing the Antarctic Pennisula.

Coupling from the Antarctic Circumpolar Vortex to the Antarctic Circumpolar Current, flow through the Drake Passage, and Eckmann transport driving the Atlantic Meridional Overturning Current would all be changed — see http://climate.gmu.edu/research/drake.php, especially Figure 4.

For reasons I do not fully understand, with global warming the circumpolar vortex has moved somewhat further south, exposing the Antarctic Pennisula.

Not exact matches

Material from both eruptions was unable to penetrate the Antarctic stratosphere at high altitudes last year because the eruptions occurred after the establishment of the winter vortex of circumpolar winds, which cuts off the upper stratosphere above Antarctica.

«In winter, the freezing Arctic air is normally «locked» by strong circumpolar winds several tens of kilometers high in the atmosphere, known as the stratospheric polar vortex, so that the cold air is confined near the pole,» said study co-author Marlene Kretschmer from the Potsdam Institute of Climate Impacts Research in Germany, in a press release.

(Polar vortices should not be confused with the circumpolar jet around the poles, which is often given the same name in the media.)

Polar vortices are technically in the upper atmosphere — but there are related circumpolar winds at the surface that are more to the point.
