Background & Aim: Energy is one of important debates in agriculture ecology and for this reason; the ratio of output and input energy in different agriculture ecosystems has been calculated. If one can reduce, input energy level into farms through the indices like poisons, fertilization, tractor energy and lab our force. In addition to the net income of the farmers, this issue would play a sign...

[1] This paper synthesizes a variety of atmospheric and oceanic data to examine the large-scale energy budget of the Arctic. Assessment of the atmospheric budget relies primarily on the ERA-40 reanalysis. The seasonal cycles of vertically integrated atmospheric energy storage and the convergence of energy transport from ERA-40, as evaluated for the polar cap (defined by the 70 N latitude circle...
