Forecasts

Seasonal forecasts of temperature and precipitation.

Flexible Forecasts
This seasonal forecasting system consists of probabilistic temperature seasonal forecasts based on the full estimate of the probability distribution.
This seasonal forecasting system consists of probabilistic precipitation seasonal forecasts based on the full estimate of the probability distribution.
Forecasts
Maps of temperature, precipitation and 500mb-geopotential height forecasts from Individual Atmospheric General Circulation Models.
Maps of sea surface temperature scenarii (SST forecasts) used to force the AGCMs.
The seasonal forecast for above-, below- and near-normal precipitation from the IRI.
The seasonal forecast for above-, below- and near-normal temperature from the IRI.
Predictions In Context
Shading on this map identifies regions where there has been below-normal or above-normal precipitation during the previous 12 months AND where the IRI seasonal precipitation forecast for the next 3 months indicates an enhanced likelihood of a reversal of these precipitation conditions.
