Origin of troposphereFrench troposphère from Classical Greek tropos, a turning (see trope) + French sphère (see sphere)
The troposphere is the lowest layer of the atmosphere with water vapor, vertical winds and temperatures that decrease as the altitude increases.
An example of the troposphere is the layer below the tropopause.
the atmospheric zone or shell below the tropopause, characterized by water vapor, vertical winds, weather, and decreasing temperatures with increasing altitude
The lowest region of the atmosphere between the earth's surface and the tropopause, characterized by decreasing temperature with increasing altitude.
The lowest and densest region of the Earth's atmosphere, extending from the Earth's surface to the tropopause. The troposphere is characterized by temperatures that decrease with increasing altitude. At the top of this region, temperatures are close to −55°C (−67°F). The weather, major wind systems, and cloud formations occur mostly in the troposphere.
From French troposphÃ¨re.
