tro·po·pause

 (trō′pə-pôz′, trŏp′ə-)
n.
The boundary between the troposphere and the stratosphere varying in altitude from approximately 8 kilometers (5 miles) at the poles to approximately 18 kilometers (11 miles) at the equator.

tropopause

(ˈtrɒpəˌpɔːz)
n
(Physical Geography) meteorol the plane of discontinuity between the troposphere and the stratosphere, characterized by a sharp change in the lapse rate and varying in altitude from about 18 km (11 miles) above the equator to 6 km (4 miles) at the Poles

trop•o•pause

(ˈtrɒp əˌpɔz, ˈtroʊ pə-)

n.
the boundary, or transitional layer, between the troposphere and the stratosphere.

tro·po·pause

(trō′pə-pôz′, trŏp′ə-pôz′)
The boundary between the upper troposphere and the lower stratosphere, varying in altitude from about 5 miles (8 kilometers) at the poles to 11 miles (17.7 kilometers) at the equator.

tropopause

The transition zone between the stratosphere and the troposphere. The tropopause normally occurs at an altitude of about 25,000 to 45,000 feet (8 to 15 kilometers) in polar and temperate zones, and at 55,000 feet (20 kilometers) in the tropics.

tropopause

the zone between the troposphere and the stratosphere where the temperature remains relatively constant above a given point on earth.

tropopause

The thin layer of the atmosphere, about 3 mi (5km) thick, that lies between the troposphere and the stratosphere.

The data showed that these storm clouds reached as high as the tropopause -- the coldest part of the atmosphere -- where they spread out much like the anvil-shaped cumulonimbus clouds that generate lightning and thunder on Earth.
Mikesell thought it occurs at the tropopause rather than in the stratosphere.
NORMAN A University of Oklahoma meteorology team, led by Steven Cavallo, is studying the role of tropopause polar vortices as a barrier in limiting predictability over the Arctic with three, five-year grants totaling $2.9 million from the U.S.
Furthermore, stable atmospheric boundaries like tropopause, stratopause, thermopause and mesopause have similar vertical distributions at different celestial bodies in atmospheres of very different chemical compositions.
Since then, many studies have used the DFA method in atmospheric temperature [3-8], cloud breaking [9], wind speed [10], relative humidity [11, 12], air pollution [13], global tropopause [14], ozone variations [15], sea surface temperature [16-18], and so on.
This could be especially true for thunderstorms forming in the tropopause, as ozone in the stratosphere has been found to have [delta][.sup.18]O values of up to +400%o.
Jet streams are found 9-16km above the surface of the Earth, just below the tropopause, and can reach speeds of 200 mph.
The optimum altitude for contrails is at the tropopause height (See "The Weather Aloft" from May 2017 that touched on the tropopause.) where we find the coldest temperatures.
These are narrow, fast-flowing, meandering westerly currents found near the tropopause, which are frequently used by commercial airlines as a means of saving time and fuel.
The top of the vertical axis is the tropopause, which means that in this study only troposphere is considered for forcing and for the simulations.
