Brückner cycle Tendency for the cyclical recurrence of runs of wet years at about 35-year intervals, with warmer and drier years in between, reported in 1890 by A. Brückner. Much attention was paid to it for a time, but its operation is obscured by the greater magnitude of the irregular year-to-year variations, and by cyclical recurrences of other periods.
