a, Ratio of the standard deviation (STD) of the high-frequency (that is, 10-day high-pass-filtered) precipitation anomalies during 2016–2020 to that during 1980–1984 in western USA (125°–110° W, 30°–50° N) and eastern USA (90°–55° W, 35°–50° N). b, Same as a but for the ratio of variability during 2001–2020 to that during 1960–1979. c, Percentage change in precipitation variability during 2016–2020 compared with 1980–1984 (that is, STD change divided by STD during 1980–1984) divided by the percent change in precipitation climatology in the western and eastern USA. d, Same as c but for the ratio between 2001–2020 to 1960–1979.
