Atmosphere as a steam engine

Abstract: Earth's atmosphere operates a steam cycle in which water vapor evaporates from the surface, expands, condenses, and returns as precipitation. The Clausius-Clapeyron law relates the incremental expansion work of saturated water vapor to latent heat converted at a Carnot efficiency corresponding to the temperature difference between evaporation and condensation. We generalize this relation to an atmospheric column with condensation occurring over a range of heights and derive the expansion work per mole of precipitated water. This includes the gravitational work associated with lifting moist air to the mean condensation height, the expansion work generated by condensation, and a correction for incomplete condensation. Using GPCP v3.3 precipitation and observational constraints on condensation height, we estimate the global steam-engine power as $W_v=4.4\pm0.9$ W/m2, close to an independent estimate of total atmospheric power, $W=W_P W_K\simeq4.3\pm0.6$ W/m2, obtained from the gravitational power of precipitation and kinetic energy generation by horizontal pressure gradients diagnosed from MERRA-2. Kinetic energy generation is $W_K\simeq3.2\pm0.3$ W/m2, of which at least two thirds is generated in the lower atmosphere. The smaller upper-atmospheric contribution, dominated by temperature-related pressure gradients, is comparable to Lorenz available potential energy generation. The agreement between steam-engine and atmospheric power is linked to condensation and precipitation fallout. By removing water from the atmospheric gas phase and enabling column-mass redistribution, precipitation maintains surface pressure gradients that drive cross-isobaric flow in the frictional lower atmosphere. The steam-engine framework thus provides a thermodynamic basis for condensation-induced atmospheric dynamics and identifies a major lower-atmospheric power pathway associated with water phase transitions.

Missing Link: Vor 40 Jahren explodierte der Reaktor in Tschernobyl
Die Crew im Atomkraftwerk wollte testen, wie sich der Reaktor bei einem Stromausfall verhält. Damit löste sie den bis dahin folgenschwersten Atomunfall aus.

The “gainfully employed robots” model I keep hearing about seems to miss the mark. People are not going to send their robots off to work for them when the company can buy the robots.

Heute vor 73 Jahren: Am 25. Mai 1953 wurde im Rahmen der Upshot-Knothole-Testserie die #Atomkanone M65, auch bekannt als Atomic Annie, auf dem Nevada Testgelände erfolgreich getestet. Dieses US Artilleriegeschütz feuerte als erstes und einziges eine nukleare Granate ab.
