Atmospheric cycling

Gas turbine systems operate on the thermodynamic cycle known as the Brayton cycle. In a Brayton cycle, atmospheric...

Despite the central role that air-sea gas exchange plays in studies of marine productivity, biogeochemical cycles, atmospheric chemistry, and climate, it has proved extremely difficult to measure air-sea gas fluxes in situ. Only in 2001 were believable direct measurements of oceanic CO2 fluxes reported in the literature (McGillis et al., 2001a). In this section we examine the various models that have been proposed to understand the basic processes that control gas exchange mechanisms, describe results from laboratory experiments, and discuss the various techniques that have been developed to try to measure gas transfer rates in situ. Finally, we describe the development of wind speed (U) based para-metrizations and assess their impact on computation of air-sea gas fluxes. 

In the nitrogen cycle, atmospheric nitrogen gas is converted to nitrates, which plants use to make biological compounds. Eventually, nitrates are converted back to nitrogen gas. 

Despite the relatively small part of anthropogenic copper in its global biogeo-chemical cycle, atmospheric transport is responsible for transboundary long range air pollution and impact in many regions of the World, especially in Europe and North America. 

In the Calvin cycle, atmospheric carbon dioxide reacts with a five-carbon molecule to form an unstable six-carbon molecule. That six-carbon molecule breaks down into two three-carbon molecules.

Floods. In the hydrologic cycle, atmospheric precipitation falls to Earth and is either evapotranspired back to the atmosphere, absorbed by vegetation, or moved downslope as overland flow that eventually becomes large enough to form stream channels. Water generally stays within the channel for most of the year. However, if the precipitation is heavy enough, the channel cannot transport all of this water and the stream overflows its banks, thereby creating floods.
