This is not your typical "winter impacts of El Niño" map. It shows the frequency of wet (green) or dry (brown) winters (December-February) across North America during the 29 El Niños from 1940-2022. Places where more than half the El Niño winters were wetter than average by any amount are colored green. (Whether a winter was above- or below-average was based on comparison with a 30-year rolling average centered on the winter in question.) Places where more than half the El Niño winters were drier than average by any amount are colored brown. Much of the southern United States is light or medium green, meaning that wetter-than-average winters were slightly more common than drier-than-average winters. Across the northern part of the contiguous United States, drier-than-average winters slightly outnumbered wet ones. NOAA Climate.gov map, based on analysis of ERA5 data by Brian Brettschneider.
