Winter temperature patterns during each La Niña “three-peat” since 1950, where a “three-peat” is defined as three consecutive winters with La Niña conditions. Note that the winter of 2022-23 is expected to complete the third such occurrence. As in the first figure above, dark red colors indicate much warmer than normal conditions, dark blue colors indicate much cooler than normal conditions, and the December–February ONI for each episode is shown in parentheses (units of °C) above each map.
