Self-Organized Critical Behavior of Acid Deposition

By employing empirical probability distribution function and power spectrum analysis together with detrended fluctuation analysis (DFA), we show that acid deposition events are analogous to avalanches of granular piles displaying self-organized criticality (SOC). Under a wide variety of circumstances, frequency distributions of hydrogen ion concentration (HIC) and weekly hydrogen deposition (WHD) of precipitation are consistent with double …
