3rd Year of La Nina Rainfall Climatology for North and South America

Forecasts for a 3rd consecutive La Nina year are confident. 3rd La Nina years are rare. Using the operational Nino index (ONI) for 1950-2022 yields 3 ENSO regimes (1956, 1975 and 2000) in which a 3rd consecutive La Nina year occurred. In that 3rd year of La Nina, widespread dryness affects the Central to Southeast U.S. and Brazil.
