| 释义 | troposphere noun environment specializeduk /ˈtrɒp.əs.fɪər/ us /ˈtrɑː.pə.sfɪr/ [ C ] the lowest part of the atmosphere of a planet: Both Mars and Earth have cirrus-rich upper tropospheres. The earth acts like a giant greenhouse with protective ozone that keeps out excessive radiation and a troposphere that helps keep heat in. the troposphere [ S ] the layer of gases surrounding the earth from the surface up to a height of about ten kilometres: （地球的）对流层 Bad ozone lives in the troposphere, everything from sea level to about 10 miles above. The stratosphere sits above the troposphere and reaches up to an altitude of 30 miles. See also asthenosphere the atmosphere biosphere exosphere hydrosphere ionosphere lithosphere mesosphere stratosphere thermosphere Saturn's troposphere does not end at a solid surface. This has nothing to do with the greenhouse effect in the troposphere. We have satellite measurements of sea surface temperature and of lower troposphere temperature. What effect do aerosols have on conditions in the troposphere?

The lower atmosphere (the troposphere) thus experiences a positive lapse rate (negative temperature change with height). This assumption requires the aspect ratio to be small, troposphere and 10-3 in the stratosphere. For example, the passing of air over mountains and hills can cause the formation and breaking of internal waves in the troposphere and stratosphere. While tritium remains in the troposphere, many reemissions are possible, but in this work only the first reemission after the release is considered. Experience has shown that this method should be used with caution as it treats the troposphere in two smoothed layers, over its entire depth. First, the eruption must be explosive enough to inject eruption products into the stratosphere, the par t of the atmosphere above the troposphere. Higher levels of pollutants in the lower troposphere may stimulate seed germination when other external conditions are inappropriate for seedling growth. A change in the current density and in the initial values of electrical power delivered to the simulated troposphere resulted in differences in the type and amount of compounds formed. These rising air currents diverge in the upper troposphere and move away from the equator at high altitude in both northerly and southerly directions.
