TroposphereNoun1. The lowest atmospheric layer; from 4 to 11 miles high (depending on latitude). Source: WordNet 1.7.1 Copyright © 2001 by Princeton University. All rights reserved. |

| Domain | Definition |
Aerospace | 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. (references) |
Geography | Lower part of the terrestrial atmosphere, extending from the surface up to a height varying from about 9 km at the poles to about 17 km at the Equator, in which temperature decreases fairly regularly wi th height. Source: European Union. (references) |
Math | Lowest atmospheric layer, between the surface and tropopause. (references) |
Military | The lower layers of atmosphere, in which the change of temperature with height is relatively large. It is the region where clouds form, convection is active, and mixing is continuous and more or less complete. See also atmosphere. (references) |
Science | The lower atmosphere, to a height of 8-15 km above Earth, where temperature generally decreases with altitude, clouds form, precipitation occurs, and convection currents are active. See atmosphere. (references) |
Solar | The lowest region of the atmosphere between the surface of the earth and the stratosphere. In the troposphere the temperature usually decreases with increasing altitude. (references) |
Weather | The lowest layer of the atmosphere and contains about 95 percent of the mass of air in the Earth's atmosphere. The troposphere extends from the Earth's surface up to about 10 to 15 kilometers. All weather processes take place in the troposphere. Ozone that is formed in the troposphere plays a significant role in both the greenhouse gas effect and urban smog. See ozone precursors, stratosphere, atmosphere. (references) |
| The inner layer of the atmosphere below about 15 km, within which there is normally a steady decrease of temperature with increasing altitude. Nearly all clouds form and weather conditions manifest themselves within this region, and its thermal structure is caused primarily by the heating of the Earth's surface by solar radiation, followed by heat transfer by turbulent mixing and convection. (references) | |
| The layer of the atmosphere from the earth's surface up to the tropopause, characteriz;;ed by decreasing temperature with height (except, perhaps, in thin layers :: see inversion, cap), vertical wind motion, appreciable water vapor content, and sensible weather (clouds, rain, etc.).

(From Wikipedia, the free Encyclopedia)
The troposphere is the lowermost portion of Earth's atmosphere and the one in which clouds and most other weather phenomena occur. This layer extends to an altitude of 16-18 km over tropical regions, decreasing to less than 10 km over the poles, and contains approximately 80% of the total air mass. Generally, jets fly near the top of this layer. The troposphere is directly below the stratosphere.
The word troposphere stems from the Greek "tropos" for "turning" or "mixing". This region, constantly in motion, is the densest layer. Nitrogen and oxygen are the primary gases within this region. The change of temperature with height is larger than in other layers, the temperature decreasing with altitude.
The tropopause marks the limit of the troposphere and the beginning of the stratosphere. The temperature above the tropopause increases slowly with height up to about 50 km.
