How To Use Tropopause In A Sentence
-
The probe will hit the coldest layer of the atmosphere, the tropopause, at about 28 miles, where expected temperatures hover around minus 390 degrees Fahrenheit (minus 200 degrees Celsius).
-
The upper boundary of the layer, known as the tropopause, ranges in height from 5 miles (8 km) near the poles up to 11 miles (18 km) above the equator.

-
Getting beyond the tropopause is a trick for us, but molecules manage to bumble their way beyond it anyway without our help.

-
Temperature generally slows or stops decreasing with height at the tropopause and (by solar heating - ozone layer) eventually starts to increase until reaching the stratopause (in winter at higher latitudes, temperature continues to decrease with height above the tropopause
RealClimate
-
Next comes the tropopause, which is the upper boundary of the troposphere.
-
The tropopause is the point of thermal equilibrium between the two and seems that this point would vary in height given a change in the GWP of the atmosphere as would the lapse rate by definition.
Unthreaded #12 « Climate Audit
-
With the lower atmosphere (the troposphere) warming and the upper atmosphere (the stratophere) cooling, another consequence is the boundary between the troposphere and stratophere, otherwise known as the tropopause, should rise as a consequence of greenhouse warming.
Climate Progress
-
The tropopause is the “roof of weather”, the top of the weather-containing troposphere.
Road Map #3 « Climate Audit
-
Strong westerlies, at times, have been observed near the tropopause over Recife, Brasil, approximately 9o from the equator.
-
The easiest is the ‘instantaneous forcing’ - the change is made and the difference in the net radiation at the tropopause is estimated.
-
We've observed warming of the Earth's land surface and oceans, cooling of the stratosphere, an increase in height of the tropopause, retreat of Arctic sea ice, and widespread melting of glaciers.
-
The tropopause can be defined as the place where the temperature stops decreasing with height and becomes constant.
-
It is generally assumed that most of the water vapor found in the stratosphere passes through the tropical tropopause which is the coldest point of the troposphere, into the stratosphere.

-
The tropopause - the boundary between these two layers - varies in altitude from 8 to 18 km (dashed white lines), depending on Earth latitude and season of the year.
-
I did ask a few days ago how tropospheric phenomena, like thunderstorms, can heat the upper-atmosphere through convection even though the bouyant energy required to release the latent heat as sensible heat does not make it past the tropopause which is not the upper atmosphere.
Mann at the NAS Panel « Climate Audit
-
It extends from the Earth's surface to the tropopause, the name given to the boundary between the troposphere and the stratosphere.
-
The whole tropical tropopause has been warmed up from cold period to warm period.
-
On Neptune, methane plays the same role as water vapor on Earth: the temperature of the socalled tropopause - a barrier of colder air separating troposphere and stratosphere - determines how much water vapor can rise into the stratosphere.
