Sentences with phrase «troposphere than at the surface»

It is likely, however, that there is slightly greater warming in the troposphere than at the surface, and a higher tropopause, with the latter due also to pronounced cooling in the stratosphere.

Personally I didn't know why globally there should be greater warming in the lower troposphere than at the surface.

It is likely, however, that there is slightly greater warming in the troposphere than at the surface, and a higher tropopause, with the latter due also to pronounced cooling in the stratosphere.

Since 1979, it is likely that there is slightly greater warming in the troposphere than at the surface, although uncertainties remain in observed tropospheric warming trends and whether these are greater or less than the surface trend.

But there is also the problem that GH warming should actually be at a faster rate in the troposphere than at the surface (according to IPCC), and this clearly doesn't seem to be the case.

Some models show more warming in the troposphere than at the surface, while a slightly smaller number of simulations show the opposite behavior.

Not exact matches

For global observations since the late 1950s, the most recent versions of all available data sets show that the troposphere has warmed at a slightly greater rate than the surface, while the stratosphere has cooled markedly since 1979.

Above the surface, global observations since the late 1950s show that the troposphere (up to about 10 km) has warmed at a slightly greater rate than the surface, while the stratosphere (about 10 — 30 km) has cooled markedly since 1979.

John Christy and Roy Spencer of the University of Alabama published a series of papers starting about 1990 that implied the troposphere was warming at a much slower rate than the surface temperature record and climate models indicated Spencer and Christy (1992).

[Response: Depends again — the upper troposphere is predicted to warm more than the surface — at least in the tropics.

In terms of the gold that a climate science denier might find in the paper, at the very least, they could argue that the fact that the troposphere isn't warming more quickly than the surface shows that the climate models are unreliable — even though the models predict just the pattern of warming that we see — with the troposphere warming more quickly than the surface over the ocean but less quickly than the surface over land.

Before allowing the temperature to respond, we can consider the forcing at the tropopause (TRPP) and at TOA, both reductions in net upward fluxes (though at TOA, the net upward LW flux is simply the OLR); my point is that even without direct solar heating above the tropopause, the forcing at TOA can be less than the forcing at TRPP (as explained in detail for CO2 in my 348, but in general, it is possible to bring the net upward flux at TRPP toward zero but even with saturation at TOA, the nonzero skin temperature requires some nonzero net upward flux to remain — now it just depends on what the net fluxes were before we made the changes, and whether the proportionality of forcings at TRPP and TOA is similar if the effect has not approached saturation at TRPP); the forcing at TRPP is the forcing on the surface + troposphere, which they must warm up to balance, while the forcing difference between TOA and TRPP is the forcing on the stratosphere; if the forcing at TRPP is larger than at TOA, the stratosphere must cool, reducing outward fluxes from the stratosphere by the same total amount as the difference in forcings between TRPP and TOA.

For the theory to hold true, the observable rate of temperature increase would be higher in the troposphere than at the earth's surface.

You see, Joanne, you have nothing in the way of an hypothesis that even explains the observed surface temperature of Earth, let alone that of Venus or at the base of the 350Km high nominal troposphere of Uranus where it's hotter than Earth.

Produce evidence of (a) the temperature of the air adjoining the surface being warmer than the surface at night, thus «stopping convection» and (b) any other inversion in calm conditions at night in the troposphere.

You haven't explained how the temperature is maintained at the Venus poles, where less than 1W / m ^ 2 of incident solar radiation reaches the surface, and not much more reaches the lower troposphere.

There's no significant radiation at the base of the nominal Uranus troposphere, but it's hotter than Earth's surface down there.

The month - to - month variability of tropical temperatures is larger in the troposphere than at the Earth's surface.

Satellites measure all the heat in the troposphere rather than just the sensible heat at the surface.

This despite the fact that GH warming in the troposphere should be greater than at the surface.

This requires that warming in the tropical upper troposphere be 2 - 3 times greater than at the surface.

The reason that the upper part of the troposphere is expected in the global average to warm more than the surface is that in the tropics is that one expects the lapse rate to closely follow the moist adiabatic lapse rate, which indeed implies more warming at altitude than at the surface.

The answer is that since the effect of CO2 is at the surface, rather than distributed throughout the troposphere, then the surface of the Antarctic ice shelves melted supplying fresh water to the sea ice edge.
