Web4 mrt. 2024 · As Earth’s surface is heated by sunlight, it radiates part of this energy back toward space as infrared radiation. This radiation, unlike visible light, tends to be absorbed by the greenhouse gases in the atmosphere, raising its temperature. The heated atmosphere in turn radiates infrared radiation back toward Earth’s surface. WebAdditionally, the troposphere has warmed because it has absorbed the energy that is no longer available to the stratosphere. In concluding, this paper has explained the mechanisms which cause the troposphere to warm and the stratosphere to cool when the atmospheric level of CO2 increases. piston mode结构

How is the troposphere warmed up

WebThe air in the first few miles of the atmosphere, the troposphere, does not significantly absorb solar radiation, instead it is warmed by contact with the ground. The surface heated air expands as it warms, becomes less dense than surrounding cooler air and rises as buoyant and turbulent bubbles. Web7 dec. 2004 · Since increasing GHGs implies an increasing temperature gradient, the temperatures must therefore ‘pivot’ around this (fixed) level. i.e. everything below that level will warm, and everything above that level will cool. Even though the stratosphere has an opposite lapse rate to the troposphere because of the ozone absorption, the effect of ...
