The boundary between the top of troposphere and the bottom of the stratosphere. Defined by the place where temperatures stop decreasing, and begin increasing, as you go up in the atmosphere.
the layer of the Earth's atmosphere that separates the troposphere from the stratosphere
upper boundary of troposphere, below stratosphere
A thin boundary layer between the troposphere and the stratosphere.
the region of discontinuity between the troposphere and the stratosphere
The tropopause is a transition region of the atmosphere between the troposphere and the stratosphere. The troposphere and the stratosphere have markedly different properties. The tropopause is located just above the troposphere and just below the stratosphere. The height of the tropopause changes during the seasons. The tropopause is located at higher altitudes in the summer and fall and lower altitudes in the winter and spring. This change in altitude, changes with the abundance of ozone overhead.
The transition region, in whih temperatures reach a minimum, between the troposphere and stratosphere.
The cold region in the earth's atmosphere located about 10 km (8 mi) above the surface, at which the usual vertical temperature decrease in the troposphere ceases; by convention, the tropopause is defined as where the temperature lapse rate to less than 2 C per kilometer for an extended depth (usually 2 km). This boundary marks the top of the troposphere and the base of the stratosphere, and can vary with season and latitude, with a altitude ranging from 6 km (4 mi) in polar regions to 16 km (10 mi) in the tropics
The boundary between the troposphere and stratosphere, usually characterized by an abrupt change of lapse rates. The change is in the direction of increased atmospheric stability. Its height varies from 15 to 20 km in the tropics to about 10 km in the Polar Regions. Often, thunderstorms reach the tropopause and can no longer accelerate and grow upward so the anvil begins to spread out and ahead of the thunderstorm.
The zone in the atmosphere that divides the troposphere and the stratosphere. The altitude of the tropopause varies with latitude, being highest above the equator (about 12 miles) and lowest near the poles (less than five miles).
The place that marks the end of the troposphere and the start of the stratosphere marked by a change in temperature.
The upper boundary of the troposphere, usually characterized by an abrupt change in lapse rate from positive (decreasing temperature with height) to neutral or negative (temperature constant or increasing with height).
Boundary between the upper troposphere and the lower stratosphere that varies in altitude between approximately 8 km at the poles to 18 km at the equator. Source: EPO.
The boundary separating the troposphere and the stratosphere
The level separating the troposphere and the stratosphere, occurring at an altitude of 5-10 miles.
Boundary between troposphere and stratosphere. Temperatures stop decreasing with altitude.
The boundary between the troposphere (q.v.) and the stratosphere (q.v.) (IPCC)
The boundary between the troposphere and the stratosphere. "Weather," as we know it, occurs within the troposphere, that part of the atmosphere closest to the Earth's surface (6.2 to 12.4 miles deep). Temperature decreases with height within the troposphere. The tropopause is marked by an abrupt change of lapse rate (the change of temperature with height).
the upper boundary of the troposphere, usually characterized by an abrupt change in how the temperature changes with height; below the tropopause temperature generally decreases with height; above the tropopause temperature generally increases with height
The narrow region separating the troposphere and the stratosphere. More information here..
The boundary between the troposphere and stratosphere, usually characterized by an abrupt change in lapse rate. Its height varies from 10 to 20 km. Regions above the tropopause have greater atmospheric stability than regions below.
The boundary between the troposphere and stratosphere, usually characterized by an abrupt change of lapse rate. The change is in the direction of increased atmospheric stability from regions below to the regions above the tropopause.
The boundary between the troposphere and the stratosphere, usually characterized by an abrupt change in lapse rate (vertical temperature gradient).
The transition zone between the troposphere and the stratosphere; characterized by an abrupt change in lapse rate.
The boundary zone or transition layer between the troposphere and the stratosphere. This is characterized by little or no increase or decrease in temperature or change in lapse rate with increasing altitude.
The atmospheric boundary between the troposphere and the stratosphere. It is usually marked by a kink in the temperature profile where the lapse rate changes from about 6.5°C per km to almost isothermal.
The tropopause is a relatively thin atmospheric transition layer found between the troposphere and the stratosphere. The height of this layer varies from 8 to 16 kilometers above the Earth's surface.
The boundary layer between the troposphere and the stratosphere characterized by its isothermal properties.
the boundary layer between the troposphere and stratosphere, where an abrupt change in temperature lapse rate usually occurs; it is defined as the lowest level at which the lapse rate decreases to 2 degrees Celsius per kilometer or less, provided that the average lapse rate between this level and all higher levels within 2 kilometers does not exceed 2 degrees Celsius per kilometer; occasionally, a second tropopause may be found if the lapse rate above the first tropopause exceeds 3 degrees Celsius per kilometer.

The tropopause is the boundary zone (or transition layer) between the troposphere and the stratosphere of the Earth's atmosphere. The tropopause is characterized by little or no change in temperature as altitude increases.
