    "abstract": "The irregular reversals of wind direction in convective turbulence are found\nto have fluctuating intervals that can be related to critical behavior. It is\nshown that the net magnetization of a 2D Ising lattice of finite size\nfluctuates in the same way. Detrended fluctuation analysis of the wind reversal\ntime series results in a scaling behavior that agrees with that of the Ising\nproblem. The properties found suggest that the wind reversal phenomenon\nexhibits signs of self-organized criticality.",
