Antarctic Circumpolar Current
The Antarctic Circumpolar Current. ACC is the only current in the global ocean to close upon itself in a circumpolar loop. This trait makes the ACC the most important current in the Earth''s climate system because it links the Atlantic, Pacific and Indian Oceans and is the primary means of inter-basin exchange of heat, carbon dioxide, chemicals, biology and other tracers.
Long-Term Variations of Global Solar Radiation and Its Potential
Therefore, long-term site-process studies related to the climate and climate change are still necessary. Solar radiation is the fundamental energy source for the earth–atmosphere system. Thus, its transfer and distribution in the atmosphere, and its reflection at the surface and the top of the atmosphere (TOA), should be investigated thoroughly.
