September2022_globalprecip_percentdiff.png

Global precipitation patterns in September 2022 shown as a percent difference from average. Places that were 200 percent or more wetter than average are green, while places that were up to 100 percent drier than average are brown. The largest-scale pattern is the contrasting drier-than-average region over the central and eastern tropical Pacific and the wetter-than-average region over the Maritime Continent. These opposite rainfall patterns are typical of the La Niña climate pattern. NOAA Climate.gov image, based on data from the Global Precipitation Climatology Project.
