The boundary between the top of the stratosphere and the bottom of the mesosphere. Defined by the place where temperatures stop increasing, and begin decreasing, as you go up in the atmosphere.
The boundary separating the upper stratosphere from the mesosphere, situated at about 50 km altitude.
Top of the stratosphere (~50 km), where temperatures stop increasing with altitude.
The temperature pause that marks the top of the stratosphere.
the boundary layer between the stratosphere and the mesosphere at about 50 to 55 kilometers (31 to 34 miles). Russian translation prepared by Nina A. Zaitseva for the Arctic Climatology Project Arctic Meteorology and Climate Atlas.
The boundary zone or transition layer between the stratosphere and the mesosphere. Characterized by a decrease in temperature with increasing altitude.
The stratopause is the level of the atmosphere which is the boundary between two layers, stratosphere and the mesosphere. In the stratosphere the temperature increases with altitude, and the stratopause is the section where a maximum in the temperature occurs.
