polar vortex

This figure shows the size of the polar vortex with respect to previous years.

This area of low ozone is confined by the polar vortex.

Saturn is the only planet known to have a warm polar vortex.

When the polar vortex is strong, the Westerlies increase in strength.

The warmer air can only move along the edge of the polar vortex, but not enter it.

Not until mid to late Spring does the polar vortex weaken and eventually break down.

But a split polar vortex might have you laughing on the other side of your hedge pretty soon.

The aircraft will be used to study the polar vortex and its influence on global weather patterns.

Closely related to this concept is the polar vortex.

"This is the first time we've seen the polar vortex split in September," Long said.

When the polar vortex is strong, westerly flow descends to the Earth's surface.

A stronger polar vortex might explain the cooling trend in the interior of Antarctica.

Near the poles are anticyclonic structures called polar vortices.

Inside the polar night jet is the polar vortex.

The chemistry of the Antarctic polar vortex has created severe ozone depletion.

Within this polar vortex, over 50% of the lower stratospheric ozone is destroyed during the Antarctic spring.

By the end of September, however, there was evidence of volcanic aerosol in the polar vortex.

During the winter/spring period, when the polar vortex is strongest, air outside of the vortex can not enter.

Odd structures known as polar vortices lie within the cold polar collars.

On Earth, the polar vortices are located in the middle and upper troposphere and the stratosphere.

It will use the Polar vortex winds to circle around the South Pole, returning after two weeks.

Different atmospheric patterns have been observed, including polar vortices, strong zonal winds, and large-scale circulation.

They said the warm polar vortex, a large-scale weather system like an atmospheric whirlpool, was unlike anything ever observed in the Sun's family of planets.

The polar vortex is not broken down and the wind reversal from westerly to easterly is less extensive.

Ozone depletion occurs within the polar vortex, particularly over the Southern Hemisphere, which reaches a maximum in the spring.
