Scaling behaviour in daily air humidity fluctuations
Abstract
We show that the daily average air humidity fluctuations exhibit non-trivial

behaviour which different from the spectral properties of other meteorological quantities. This feature and the fractal spatial strucure found in clouds make it plausible to regard air humidity fluctuations as a manifestation of self-organized criticality. We give arguments why the dynamics in air humidity can be similar to those in sandpile models of SOC.
