Sentences with phrase «winter polar regions»

The lapse rate (despite the temperature inversions near the surface at night and in the winter polar regions) insures that the radiation of the air absorbed by the surface is slightly less than the radiation of the surface absorbed by the air.

The new images show ozone in spring, suggesting that «global winds are inhibiting the spread of water vapor from the rest of the planet into winter polar regions.»

Real - time data transmission from remotely operated instruments is key in polar regions, where continuous climate data is particularly important and maintaining personnel in the Antarctic through the winter is expensive and hazardous, says Rita Colwell, an environmental microbiologist at the University of Maryland, College Park, and another co-author of the NRC report.

«We're saying they're connected, and certainly the fact that this warming of the Arctic is taking place up in the stratosphere, and that warming over the polar region is related to the increase in severe winter weather,» he said.

With the exception of glaciers that terminate in the ocean, and glaciers in the polar regions or at extreme high altitudes where the temperature is always below freezing, essentially just two things determine whether a glacier is advancing or retreating: how much snow falls in the winter, and how warm it is during the summer.

Smaller obliquity transfers annual average insolation from higher latitudes (would make polar regions darker) to lower latitudes and reduces the seasonal ranges (would make winters less dark for less long).

The Arctic polar vortex exhibited widespread regions of low temperatures during the winter of 2005, resulting in significant ozone depletion by chlorine and bromine species.

They can scoot They travel a lot, spending summers feeding in polar regions and making the long trip to the Equator as winter comes along.

Also, as you well know any temperature change at the tropics would be small; most of the temperature change would be in the polar regions; in the mid latitudes most of the temperature change would be in winter and at night.

Chemical ozone destruction occurs over both polar regions in local winter — spring.

But in polar regions [within arctic circle] one is still going to have 6 months per year of darkness and therefore will still have freezing weather, though polar ice may not form during the winter.

So an increased GHG effect should manifest in the polar regions in a decrease in winter sea ice extent and a smaller increase in summer sea ice extent relative to the winter maximum extent (ie a smaller annual range in sea ice extent).

And on Mars CO2 gas freezes out of the atmosphere in the polar region at winter.

The largest decreases have occurred at the highest latitudes in both hemispheres because of the large winter / spring depletion in polar regions.

For the Upper Plains, Midwest and Great Lakes regions, the polar jet stays locked in Canada, allowing warmer - than - normal temperatures to persist for much of the winter.

A long - lived paradigm in polar oceanography is that arctic pelagic ecosystems, characterized by short food webs, remain in a dormant state throughout most of the winter season beneath the sea - ice cover, which can last 8 — 10 months in some regions.

But if the winters were still cold enough to freeze the polar regions (it wouldn't matter whether the temperature was -20 degC or -22 degC for example) a cooler summer would thaw less of it and the ice cap would expand.

Partly because they give birth on mobile pack ice, harps have their pups earlier in the season than all other Arctic seals, which means that in some regions, they are a critical food source for polar bears that have eaten little over the winter months.

Also, as far as temperature changes across the year are concerned, in the polar regions right at the surface, the main warming will be in the winter months.

Again, I point out that «Industry, transportation, and biomass burning in North America, Europe, and Asia are emitting trace gases and tiny airborne particles that are polluting the polar region, forming an «Arctic Haze» every winter and spring.»

This in turn may explain the recent arctic outbreaks in mid-latitude regions of the Earth during the winter months, as pressure and wind patters force arctic air out of the polar regions and into the mid-latitudes.

The data on this winter's ice buildup came on the day that international ministers gathered in Washington to address issues facing Earth's polar regions, which have been disproportionately affected by global warming.

The latitudinal temperature gradient in summer is much smaller, thus providing less drive for exchange of air masses between middle latitudes and polar regions — and when exchange occurs the effect on temperature is less than that caused by a winter «polar express» of Arctic (or Antarctic) air delivered to middle latitudes.

Northern hemisphere winter weather patterns are a complex interplay between the upper atmosphere conditions over polar regions and mid-latitude conditions over the oceans and on land.
