“It extends from the Earth's surface to the tropopause, the name given to the boundary between the troposphere and the stratosphere.”
“The tropopause can be defined as the place where the temperature stops decreasing with height and becomes constant.”
“The vertical distribution of the actual atmosphere shows clearly a tendency of bending or inflexion near the tropopause between the troposhere and the stratosphere in logarithmic scale.”
