| Zusammenfassung |
In their paper "Biotic pump of atmospheric moisture as driver of
the hydrological cycle on land", Makarieva and Gorshkov (Hydrol. Earth
Syst. Sci., 11, 1013–1033, 2007) derive from "previously
unstudied" properties of atmospheric water vapor, the existence of
a hitherto unknown "evaporative force". From this, a novel
physical principle is deduced, according to which low-level air flows
from regions with weak, to regions with strong evaporation. As such,
natural forests are claimed to "suck in" moist air from the ocean,
a process labeled the "biotic pump of atmospheric moisture".
This commentary focuses on the physical foundations of the Biotic Pump
Theory (BPT). It is shown that the "evaporative force" on which the
theory is built, is not supported by basic physical principles. The problem
of moisture transport and its dependence on vegetation cover considered by
Makarieva and Gorshkov is certainly important, but cannot be solved
along the lines proposed by them. |
