Layers of the Atmosphere - National Oceanic and Atmospheric Administration
WEBAug 20, 2024 · Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere. The transition boundary which separates the mesosphere from the stratosphere is called the stratopause. Stratosphere. The stratosphere extends from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km).
Stratopause | meteorology | Britannica
WEBThe stratopause caps the top of the stratosphere, separating it from the mesosphere near 45–50 km (28–31 miles) in altitude and a pressure of 1 millibar (approximately equal to 0.75 mm of mercury at 0 °C, or 0.03 inch of mercury at 32 °F).

WEBMay 24, 2024 · At the top of the stratosphere lies the stratopause. Like the tropopause, the stratopause is an isothermal layer that separates the stratosphere from the mesosphere.
The Stratosphere - Center for Science Education
WEBThe lower boundary of the stratosphere can be as high as 20 km (12 miles or 65,000 feet) near the equator and as low as 7 km (4 miles or 23,000 feet) at the poles in winter. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause.

WEBAug 22, 2024 · The stratopause caps the top of the stratosphere, separating it from the mesosphere near 45–50 km (28–31 miles) in altitude and a pressure of 1 millibar (approximately equal to 0.75 mm of mercury at 0 °C, or 0.03 inch of mercury at 32 °F). In the mesosphere, temperatures again decrease with increasing altitude.
Stratopause - an overview | ScienceDirect Topics
WEBThe stratopause is defined as the upper boundary of the stratosphere, located at about 50 km above the Earth's surface, where there is a maximum in temperature and a reversal of its gradient with the overlying mesosphere.
The Mesosphere - Center for Science Education
WEBThe boundary between the mesosphere and the thermosphere is called the mesopause. At the bottom of the mesosphere is the stratopause, the boundary between the mesosphere and the stratosphere. This diagram shows some of the features of the mesosphere.
