TROPOSPHERIC CONVECTION


Tropospheric convection is a key process by which the atmosphere transports water and energy and in the process clouds are created. Clouds and water vapour are very important in bringing rain locally and to global climate. Both have a distinct effect on the net energy absorbed and emitted by the planet. As do greenhouse gases. The amount of net absorbed energy creates our climate.




ATMOSPHERIC INVERSION LAYERS


An inversion:


This layer of stable air suppresses or resists vertical movement of air.



Universe


Atmosphere


Earth



The surface temperature on our planet ought to be on average approximately 15 degrees Celsius.

A higher content of atmospheric greenhouse gases results in an increased absorption and reabsorbing cycle.  

Greenhouse Gases

Gases in the atmosphere such as carbon dioxide do what the roof of a greenhouse does. Trapping solar heat  that is responsible for our weather as we know it.

Inversion layers are blankets of air trapping various sorts of air pollutants. Natural ventilation by the convection mechanism is not possible.

More greenhouses gases results more absorbed heat in the atmosphere.
