Discussion of this paper got quite heated on Lucia Liljegren’s blog and elsewhere a year or so ago. Now it has been published in a high impact journal. Hopefully Lucia might stop by to explain her objections, and tell us what if anything has changed in this final version. This is potentially an important paper. It remains to be seen if it will become accepted and built on by people working in the area of atmospheric thermodynamics. The authors website is interesting: http://www.bioticregulation.ru/

Abstract. Phase transitions of atmospheric water play a ubiquitous role in the Earth’s climate system, but their direct impact on atmospheric dynamics has escaped wide attention. Here we examine and advance a theory as to how condensation influences atmospheric pressure through the mass removal of water from the gas phase with a simultaneous account of the latent heat release. Building from fundamental physical principles we show that condensation is associated with a decline in air pressure in the lower atmosphere. This decline occurs up to a certain height, which ranges from 3 to 4 km for surface temperatures from 10 to 30 °C. We then estimate the horizontal pressure differences associated with water vapor condensation and find that these are comparable in magnitude with the pressure differences driving observed circulation patterns.
