Sentences with phrase «for polar air»

In autumn 1939 naval activities squeezed the heat out of the seas more quickly, freeing the way for polar air from the high North and Northeast.

Not exact matches

For example, in Earth's atmosphere, very long waves mix cold air from the polar regions to mid-latitudes, which often lead clouds to form or dissipate.

Katabatic winds, caused by cold air accelerating as it slides off the polar plateau, have battered us for 36 hours.

As a result of atmospheric patterns that both warmed the air and reduced cloud cover as well as increased residual heat in newly exposed ocean waters, such melting helped open the fabled Northwest Passage for the first time [see photo] this summer and presaged tough times for polar bears and other Arctic animals that rely on sea ice to survive, according to the U.S. Geological Survey.

Bacteria, however, have remained Earth's most successful form of life — found miles deep below as well as within and on surface rock, within and beneath the oceans and polar ice, floating in the air, and within as well as on Homo sapiens sapiens; and some Arctic thermophiles apparently even have life - cycle hibernation periods of up to a 100 million years while waiting for warmer conditions underneath increasing layers of sea sediments (Lewis Dartnell, New Scientist, September 20, 2010; and Hubert et al, 2010).

It's unlikely that truly polar air will invade the Lower 48 for the rest of the month, which marks the end of meteorological winter.

Thus instead of a strong zonal wind that keeps cold polar air locked in the Arctic, there is a tendency for a less zonal flow and thus more cold air outbreaks to middle latitudes.

Thus instead of a strong zonal wind that keeps cold polar air locked in the Arctic, there is a tendency for more cold air outbreaks to middle latitudes.

Slides to teach the characteristics of tropical, polar, maritime and continental air Symbols to represent each of these air masses are included The lesson ends with a quick 4 mark multiple choice quiz to check for understanding This lesson is suitable for ages 13 to 18 and is a great introduction to air before monsoons, mid lattitude cyclones or fohn winds are taught.

Common to all variations of the breed is an unmistakable sound that didn't change dramatically when the air - cooled boxer was replaced by the water - cooled engine in late 1997; a less - than - ideal weight distribution combined with a high polar moment of inertia; compromised packaging with little room for luggage; and a driving experience dominated by phenomenal grip and traction — while it lasted.

While the Endangered Species Act is applied to species both inside and outside United States borders (polar bears and North Atlantic right whales, for instance), the Clean Air Act has no applicability to sources of emissions elsewhere.

As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.

Excerpt: Livermore CA (SPX) Nov 01, 2005 If humans continue to use fossil fuels in a business as usual manner for the next several centuries, the polar ice caps will be depleted, ocean sea levels will rise by seven meters and median air temperatures will soar 14.5 degrees warmer than current day.

For periods before 1958, CO2 levels are determined from air bubbles trapped in polar ice cores.

Keeling's record of data from Mauna Loa is considered one of the best and most consistent climate records anywhere, though scientists also use other sources for atmospheric data, including samples of air trapped in polar ice, to analyze CO2 levels in past millennia.

Do GCM's «create» cold fronts and the arctic air flows when they run, or are they «static» heat exchange models only (radiation received and radiation released are obviously their «drivers»... But what happens after the air masses have been «driven» for the equal of one or two «years» — do we see flows in the tropics, mid-latitudes, and polar latitudes than resembles earth's circulation?

With today's technology some kind of pattern recognition program could classify upper air maps and then compare the pattern from, for example, the «polar vortex» and see if that pattern is unique or exhibits any trend in occurrence.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

That is the reason for the observation of more frequent and intense incursions of polar air across middle latitudes in recent years.

CO2 trends for earlier times have been derived from measurements of CO2 in air trapped in bubbles in polar ice and in mountain glaciers.

The jet stream changes which drive cold air from the polar regions has provided colder conditions for the past 3 years, any changes to cloud cover extent which is also proposed by harmonic drivers will further increase the influence from exterior sources.

For dry cold polar air at -60 deg C and 1 atm pressure, the concentration of CO2 is about 390 ppmv, and there is 22.3 mmoles per cubic meter.

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.

The jet stream is short for «tropospheric polar jet stream,» and is a current of fast - moving air found in the area of the atmosphere where weather occurs and jets fly.

For this study, the area - weighted polar cap geopotential height and air temperature anomalies (PCH and PCT) were computed for the months December through February using the National Centers for Environmental Prediction (NCEP) reanalysis at global 2.5 ° resolution for latitudes north of 65 ° N, using the period 1950 to 2016 for analysisFor this study, the area - weighted polar cap geopotential height and air temperature anomalies (PCH and PCT) were computed for the months December through February using the National Centers for Environmental Prediction (NCEP) reanalysis at global 2.5 ° resolution for latitudes north of 65 ° N, using the period 1950 to 2016 for analysisfor the months December through February using the National Centers for Environmental Prediction (NCEP) reanalysis at global 2.5 ° resolution for latitudes north of 65 ° N, using the period 1950 to 2016 for analysisfor Environmental Prediction (NCEP) reanalysis at global 2.5 ° resolution for latitudes north of 65 ° N, using the period 1950 to 2016 for analysisfor latitudes north of 65 ° N, using the period 1950 to 2016 for analysisfor analysis69.
