Predicting Characteristics of the Water Cycle From Scaling Relationships

Predicting Characteristics of the Water Cycle From Scaling Relationships

A. G. Hunt, B. Faybishenko, B. Ghanbarian

A theory of the water cycle, based on the hypothesis that ecosystems that best convert atmospheric carbon to biomass will dominate for given climate and substrate, has been expanded to address both water- and energy-limited catchments. The predictions generate the observed limits on ET across the spectrum of climates using observed or theoretical values of plant root fractal dimensionality. Given that the hypothesis of evolutionary selection is consistent also with paleo-climatic data – in particular, the cooling of Earth with a warming sun, as well as the extreme non-equilibrium of the Earth’s atmosphere – it removes impetus for considering the strong Gaia hypothesis.
