Sentences with phrase «temperatures over the pole»

The air inside this vortex, which is created by a combination of cold temperatures over the pole and the rotation of the Earth, is much colder than the air outside.

Not exact matches

Modeling Pluto's temperatures showed that when averaged over Pluto's 248 - year orbit, the latitudes near 30 degrees north and south emerged as the coldest places, far colder than either pole.

Only over the past 34 million years have CO2 concentrations been low, temperatures relatively cool, and the poles glaciated.

re Gavin @ 223 I know what the mean global temperature is (actually, I don't, see below) but the question was why is this a meaningful metric for looking at changes over time, when you could get the same global mean from very different distributions of temperature (eg increase the poles, decrease the tropics) which would have very different interpretations of energy balance (at least if I am right that humidity matters)?

Is not all over lapping absorption molecules the same, and therefore would it not take an exponentially larger increase in CO-2 to increase temperature in the tropics as opposed to the poles?

The temperature at the poles of Venus (over 720K) can not be explained by any «runaway greenhouse effect» because there is less than 1W / m ^ 2 from the Sun that gets through the Venus atmosphere to the surface at the poles.

Temperatures on the Tibetan Plateau — sometimes called Earth's «third pole» — have warmed by 0.3 °C (0.5 °F) per decade over the past 30 years, about twice the rate of observed global temperature increases.

By contrast, air temperatures over the Antarctic region for the same period were above average in some areas, such as the Antarctic Peninsula and near the pole, but below average in others.

If one compares temperature in the stratosphere at 10hPa at the poles and over the equator the thing that sticks out is the dramatic increase in temperature at 10hPa over Antarctica around 1978.

However, the strong fall in temperature throughout the stratosphere over the Equator that accompanies these winter events over the poles points to a solar influence.

Over millennia, marine life have endured and responded to CO2 levels well beyond anything projected, and temperature changes that put coral reefs and tropical plants closer to the poles or had much of our land covered by ice more than a mile thick.

The strongest evidence in support of climate change is the melting of the polar ice caps, Langcake acknowledges, noting the temperature in Antarctica rose by 2.5 degrees centigrade between 1945 and 1995 and a Norwegian study supporting the idea of a rapidly accelerating melt at both poles, but claims this theory may not be borne out over a longer period.

Those numbers are meaningless as the average temperature of the surface of the Moon is between 80 °C on the lit face and -200 °C on the dark face and averaged over a lunar day it's 98 K at the poles and 206 K at the equator.

Even if the temperature e.g. at the poles, the sink places, dropped 1 °C more than average, that doesn't make much difference: the current CO2 level at about 400 ppmv gives about the same partial pressure of 400 microatm everywhere over the oceans (minus a few % due to water vapour).

A small temperature increase at the poles leads to still greater warming over time, making the poles the most sensitive regions to climate change on Earth.

I think a direct comparison over the area that is common to all these analyses will help resolve some confusions because it removes one of the big uncertainties in observed estimates of global temperature and that is what is happening over the poles.

The CO2 wavelengths always look like the tropopause temperatures no matter if they are measured over the desert or the poles, which tells us we are seeing emissions from high in the atmosphere, not re-emitted near the surface.

For instance, over a period of time, if I observe, perhaps, that temperatures are falling, ice cover is increasing over the poles and / or that sea levels either remain static or drop.
