Theory of condensation-induced atmospheric circulation: new results

Makarieva A.M., Gorshkov V.G. (2010) Potential energy of atmospheric water vapor and the air motions induced by water vapor condensation on different spatial scales. arXiv:1003.5466v1 [physics.gen-ph]. Abstract. PDF (0.7 Mb).

Our readers interested in the biotic pump physics will know of the new developments in the condensational theory of atmospheric circulation. In particular, horizontal pressure gradients produced by condensation of water vapor in the adiabatically ascending air, are derived from the consideration of the continuity equation. (In brief, the same result was described in two lines in the second Phys. Lett. A. paper, see equation (4) there.) The energy budget of the rotating hurricane eye is considered in detail. Also, it is shown that if the Earth's atmosphere had been deprived of the bulk of non-condensable components, nitrogen and oxygen, the condensation-induced circulation would stop. This is because adiabatic lapse rate for a pure vapor atmosphere coincides with its hydrostatic equilibrium value, zeroing the evaporative-condensational force. The dependencies of maximum wind speed in hurricanes on the conserved angular momentum and temperature are presented. Tornadoes are described in the pole approximation. This publication summarizes the results of our activities during the winter of 2009-2010.
