Troposphere
</dt>
That portion of the atmosphere
from the earth's surface to the stratosphere;
that is, the lowest 10 to 20 kilometers of the atmosphere. The troposphere is
characterized by decreasing temperature with height, appreciable vertical wind
motion, appreciable water vapor content, and weather. Dynamically, the
troposphere can be divided into the following layers: surface
boundary layer, Ekamn layer, and free
atmosphere. See atmospheric
shell. [[/a>|/a>
