A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 08/19/2025 for the next 7 and 14 days.
The calibrated sub-seasonal multi-model forecast CPTEC/INPE-FUNCEME is generated through scientific cooperation between CPTEC/INPE and FUNCEME, and comes from a set of 4 global models (a Brazilian model, BAM-1.2/CPTEC, and three US models, CFSv2/NCEP, GEFSv12/NCEP and ESRL/NOAA, the latter three from the SubX project). Brazilian model, BAM-1.2/CPTEC, and three US models, CFSv2/NCEP, GEFSv12/NCEP, and ESRL/NOAA, the latter three from the SubX project). The forecast precipitation anomalies are determined in relation to the climatological period from 1999 to 2016. The outputs for the 7 and 14-day forecast intervals are shown below, detailing the forecast behavior of the basins of interest.
Forecast for the next 7 days
The figure above shows the forecast for the 7-day interval between 08/20/2025 e 08/26/2025, precipitation deficit forecast (orange) over the northeast of the monitored region, concentrated on the main course of the Amazon River in Brazilian territory, the basins of the Abacaxis, Branco, Curuá Una, and Iriri rivers, the basins on the left bank of the Amazon River in the northeast of the state of Amazonas and in the northeast and northwest of the state of Pará, Tapajós, Teles Pires, and Xingu. Forecast of positive precipitation anomalies (blue) over the main course of the Amazon River in Peruvian territory and the hydrographic basins of the Beni, Juruá, Jutaí, Mamoré, Napo, and Ucayali rivers. Forecast of rainfall close to climatology (white) over the other monitored basins.
Forecast for the next 14 days
The figure above shows the prognosis for the 14-day interval between 08/20/2025 e 09/02/2025, forecast of precipitation deficit (orange) over the northeast of the monitored region, concentrated over the main course of the Amazon River in Brazilian territory, the basins of the Branco, Curuá Una, and Iriri rivers, and the basins on the left bank of the Amazon River in the northeast of the state of Amazonas and in the northeast and northwest of the state of Pará.
