The reality can be seen in the figure “Observed lapse rate and the tropopause”.    From Wordnik.com.  [Unthreaded #19 « Climate Audit] Reference

So, in my personal list of GW fingerprints and things to watch, I put tropopause height.    From Wordnik.com.  [more bender on Emanuel « Climate Audit] Reference

At the upper edge of the troposphere is a narrow transition zone known as the tropopause.    From Wordnik.com.  [Atmosphere layers] Reference

The height of the tropopause varies from about 10 km at the poles to 17 km over the equator.    From Wordnik.com.  [Impact of ozone on climate change] Reference

There would be additional feedback if the altitude of the tropopause increased with increasing temperature.    From Wordnik.com.  [Gerry North's Suggested Reading on Climate Models « Climate Audit] Reference

Outside was a darker night than ordinary, for a great dustcloud borne along the tropopause had veiled the stars.    From Wordnik.com.  [The Day of Their Return]

This layer extends from the tropopause (roughly 12 kilometers) to roughly 50 kilometers above the earth's surface.    From Wordnik.com.  [AP Environmental Science Chapter 4- The Atmosphere] Reference

Thus the tropopause is in one sense a line on temperature plot -- it is only the height at which the air is coldest.    From Wordnik.com.  [Mother Of Storms]

The fact that commercial jet aircraft do indeed fly just above or below the tropopause supports the first hypothesis.    From Wordnik.com.  [Impact of ozone on climate change] Reference

But ozone near the tropopause has a much larger influence on the radiative balance compared to ozone at surface level.    From Wordnik.com.  [Impact of ozone on climate change] Reference

It is a much more effective greenhouse gas at the tropopause where temperatures of – 60 to – 80°C are encountered.    From Wordnik.com.  [Impact of ozone on climate change] Reference

I was quite intrigued by an article by Santer or someone like that arguing that the height of the tropopause had increased.    From Wordnik.com.  [Annan on Hegerl et al « Climate Audit] Reference

Climatologists, OTOH, oversimplify IMO when they show the effect of CO2 as a change in forcing at the tropopause in W/sq.m.    From Wordnik.com.  [Unthreaded #6 « Climate Audit] Reference

If the stratosphere is indeed IR transparent, then forcing at the tropopause can only change if the solar constant changes.    From Wordnik.com.  [Unthreaded #6 « Climate Audit] Reference

For long years it has been assumed that the sole reason for the tropopause being higher at the equator is the surplus heat.    From Wordnik.com.  [Gerry North's Suggested Reading on Climate Models « Climate Audit] Reference
