The Maproom explores historical rainy season onset date based on user-defined definitions.
The date when the rainy season starts is critical to agriculture planification, in
particular for planting.
This map shows the historical probability of seasonal average temperature falling
within the upper (hot), middle (normal), or bottom (cold) one-third ("tercile") of
the 1951-2007 historical distribution in Guatemala given the state of ENSO (El Niño,
Neutral, La Niña) during that same season.
This map shows the historical probability of weather-within-climate characteristics
of temperature falling within the upper (High), middle (normal), or bottom (Low) one-third
("tercile") of the 1980-2017 historical distribution in Guatemala given the state
of ENSO (El Niño, Neutral, La Niña) during that same season.
The Caribbean Low Level Jet (CLLJ) index presented here has been used by some authors
to understand and forecast rainfall variability in regions of Central America, northern
South America and the Caribbean.
This seasonal forecasting system consists of probabilistic precipitation seasonal
forecasts based on the full estimate of the probability distribution.
