American Heritage® Dictionary of the English Language, Fourth Edition
- 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.
Wiktionary
- n. The zone of transition between the troposphere and the stratosphere (approximately 13 kilometers). The tropopause normally occurs at an altitude of between 25,000 and 45,000 feet in polar and temperate zones. It occurs at 55,000 feet in the tropics.
WordNet 3.0
- n. the region of discontinuity between the troposphere and the stratosphere
Etymologies
- tropo- (“troposphere”) + -pause (“discontinuance”). (Wiktionary)
Examples
“Getting beyond the tropopause is a trick for us, but molecules manage to bumble their way beyond it anyway without our help.”
“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.”
“The tropopause is the “roof of weather”, the top of the weather-containing troposphere.”
“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.”
“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.”
“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.”
“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.”
“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.”
“All the earth’s weather occurs within the troposphere, a six-mile band between the earth’s surface and the atmospheric lid known as the tropopause.”
“At the upper edge of the troposphere is a narrow transition zone known as the tropopause.”
