One of the mysteries of the English language finally explained.
The interface between the troposphere and the stratosphere.
- ‘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).’
- ‘It extends from the Earth's surface to the tropopause, the name given to the boundary between the troposphere and the stratosphere.’
- ‘The easiest is the ‘instantaneous forcing’ - the change is made and the difference in the net radiation at the tropopause is estimated.’
- ‘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.’
- ‘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.’
Early 20th century: from Greek tropos ‘turning’ + pause.
