Sentences with phrase «temperature in the stratosphere»

Oddly, such low temperatures in the stratosphere could be a consequence of elevated levels of greenhouse gases.

Specifically, net temperatures in the stratosphere have remained essentially unchanged since the late 1990s.

It normally reaches its widest extent in the southern hemisphere in the spring (August and September), as extreme cold temperatures in the stratosphere facilitate chemical reactions on the surface of polar stratospheric clouds.

Unlike the troposphere, temperature in the stratosphere increases with height — similar to warm air aloft in the troposphere putting a cap on cloud formation.

In the fall, as temperatures in the stratosphere drop, the polar vortex begins to revive.

These polar clouds, which are composed of frozen nitric acid and sulfuric acid, form when temperatures in the stratosphere fall below minus 108 F (minus 78 C).

In addition, greenhouse gases can affect ozone cover, by affecting temperature in the stratosphere and by altering atmospheric circulation patterns in a way that changes the distribution of ozone over the planet, moving it away from the tropics.

An unusual persistence of cold temperatures in the stratosphere into March, allowing longer lifetimes for the polar stratospheric clouds that enable conversion of pollutant gases into ozone - destroying chlorine.

This year, more ozone has been lost over the Arctic due to unusually cold temperatures in the stratosphere, and these have been fed by a stronger circulation pattern called the polar vortex throughout the winter, according to Ross Salawitch, a professor at the University of Maryland, and one of Rex's collaborators.

Unusually low temperatures in the stratosphere, even cold records, are at fault — creating conditions whereby ice crystals form in so called polar stratospheric clouds.

The result: colder temperatures in the stratosphere.

It also recorded wind speeds and temperatures in the stratosphere, as well as the energy Earth received from the sun.

While the Arctic was warmer than average at ground level this winter, temperatures in the stratosphere were colder.

If ozone levels decline, for instance, temperatures in the stratosphere will fall.

Thanks to unusually cold temperatures in the stratosphere and chlorine lingering in the stratosphere, the part of atmosphere where the ozone layer is located, the Arctic saw its first official ozone hole this spring.

But this year, an Arctic counterpart emerged for the first time, thanks to unusually cold temperatures in the stratosphere plus lingering ozone - destroying pollutants.
