This map shows the historical probability (given in percentile) of seasonal average
monthly rainfall falling within the upper (wet), middle (normal), or bottom (dry)
one-third ("tercile") of the 1991-2020 historical distribution in Malawi given the
state of ENSO (El Niño, Neutral, La Niña) during that same season.
