The boundary between the stratosphere and the
mesosphere. It occurs at a height in the atmosphere of approximately 50
kilometers; however this depends on latitude. The atmosphere is
characterized by a decrease in pressure with respect to increased
altitude. More importantly, regions within the atmosphere like the
troposphere, stratosphere, and mesosphere are distinguishable because of
distinct temperature gradients with relatively well-defined starting and
ending points. The stratopause is the highest portion of the stratosphere,
with a temperature of approximately 0 degrees Celsius; the stratopause can
also be described as the warmest region between the mesosphere and the
stratosphere.
