tropopause

If conditions allow, the air will be able to continue rising and reach the Tropopause at a level of 30,000 feet or more.

This point of equilibrium is often marked by the tropopause.

The tropopause is a layer which separates two very different types of air.

It is also possible to define the tropopause in terms of chemical composition.

This water is often above the tropopause where little water usually reaches.

Eight kilometers high in the atmosphere near the tropopause, the winds change direction.

She was passing through the stratosphere, approaching the cold air of the tropopause.

The result is a wind which increases with altitude through the tropopause and upward to 100,000 feet or above.

These experiments lead to his discovery of the tropopause and stratosphere.

But the measurements show that these differences are small, for example only a few Kelvin at the tropopause.

The tropopause cloud shape is roughly circular and spread out.

There is no Tropopause in the jet standard atmosphere.

The tropopause is the boundary between the troposphere and stratosphere.

At maturity, they have very strong updrafts that can penetrate the tropopause.

So the tropopause is where the troposphere ends (7 to 14 kilometers high).

Between the two layers there is the tropopause.

It has a real consequence; air below the tropopause cannot rise above it easily.

Louise's concern for global warming was fuelled by her husband's interest in the tropopause.

Aircraft, balloons, small rockets and satellites are used to study the tropopause, but each has serious shortcomings.

A model for transport across the tropical tropopause.

In it temperature decreases with height reaching a minimum of about 36 K at the tropopause.

Visible optical depths greater than 0.2 were observed during flight segments flown above the tropopause.

The tropopause does not act as a barrier to transmission of freons and halons, however.

Standing waves normally do not extend above the tropopause at temperate latitudes.

The heat energy creates powerful rising air currents that swirl upwards to the tropopause.
