摘要：

We show that the daily average air humidity fluctuations exhibit nontrivial 1/f(alpha) behavior which is different from the spectral properties of other meteorological quantities. This feature and the fractal spatial structure 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 that in sandpile models of self-organized criticality.
