troposphere: see atmosphere atmosphere [Gr.,=sphere of air], the mixture of gases surrounding a celestial body with sufficient gravity to maintain it. Although some details about the atmospheres of other planets and satellites are known, only the earth's atmosphere has been well studied, the ..... Click the link for more information. . troposphereLowest region of the atmosphere, bounded by the Earth below and the stratosphere above, with the upper boundary being about 6–8 mi (10–13 km) above the Earth's surface. The troposphere is marked by decreasing temperature with height, which distinguishes it from the stratosphere. Most clouds and weather systems occur in the troposphere. troposphere the lowest atmospheric layer, about 18 kilometres (11 miles) thick at the equator to about 6 km (4 miles) at the Poles, in which air temperature decreases normally with height at about 6.5°C per km troposphere [′trōp·ə‚sfir] (meteorology) That portion of the atmosphere from the earth's surface to the tropopause, that is, the lowest 10 to 20 kilometers of the atmosphere.

The intense lower tropospheric geopotential height gradients north and east of each cyclone resulted in strong 850 mb onshore jets, a key element in providing moisture convergence over the Megalopolis (Kocin and Uccellini 2004a). urban communities for the period 1987-2000 to estimate the exposure-response curve for tropospheric [O. The best current general circulation models have predicted that tropospheric temperatures at heights in the atmosphere of a few kilometers should track surface temperatures. |
