The Global Atmospheric Circulation on Moist Isentropes
The global atmospheric circulation transports energy from the equatorial areas of the Earth to more northward latitudes. This air is passed through a poleward flow of high-energy and an equatorward flow of air with lower energy content. These results are distinctively hard to determine so scientist have taken averages to determine the results. According to studies, the total mass transport by the circulation is twice as large when averaged on moist isentropes than dry Isentropes. The mass transport of air from moist isentropes is a reason why more warm air rises into the upper troposphere within mid-latitudes and warm air in the polar regions.
I think it is interesting how different air circulations from natural phenomena have been a cause to ice melts in the polar regions. Many of the results of global warming have been human caused, however, these air circulations show to be purely natural. Though the dramatic results in the polar regions are not purely a cause of the distribution of warmer air, they do have a cause. I also find this article interesting because it relates to an idea we learned a few chapters ago about energy in the biosphere. The global atmospheric circulation is an excellent example of how energy is not created nor destroyed but rather recycled. The effects of it recycling can be positive because it is a main reason why things operate, but it can be negative in the sense of the polar ice caps melting. All in all, I think learning about the environment is important to understanding how it can be fixed.
