A multi-model sub-seasonal forecast CPTEC/INPE-FUNCEME produced on 08/5/2025 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 08/06/2025 e 08/12/2025, predominance of positive precipitation anomalies (blue) concentrated in the north of the monitored region, over the main course of the Amazon River in Brazilian and Peruvian territories, the hydrographic basins of the Abacaxis, Branco, Coari, Curuá Una, Iriri, Javari, Juruá, Jutaí, Madeira, the left bank basins of the Amazon River in the northeast of the state of Amazonas and in the northeast and northwest of the state of Pará, Negro, Purus, Tapajós, Tefé, Teles Pires, Ucayali, Xingu, and the main course of the Solimões River. There is no forecast of precipitation deficit (orange) concentrated over the monitored region. Rainfall forecast close to climatology (white) in the northwest and south of the monitored region, over the basins of the Aripuanã, Beni, Guaporé, Içá, Japurá, Ji-Paraná, Juruena, Mamoré, Marañon, and Napo rivers.
Forecast for the next 14 days
The figure above shows the prognosis for the 14-day interval between 08/06/2025 e 08/19/2025, predominance of positive precipitation anomalies (blue) over much of the monitored region, concentrated over the main course of the Amazon River in Peruvian territory, the hydrographic basins of the Abacaxis, Aripuanã, Beni, Coari, Curuá Una, Içá, Iriri, Japurá, Javari, Juruá, Juruena, Jutaí, Madeira, Marañon, basins on the left bank of the Amazon River in the northeast of the state of Amazonas and in the northwest of the state of Pará, Negro, Purus, Tapajós, Tefé, Teles Pires, Ucayali, Xingu, and the main course of the Solimões River. Forecast of precipitation deficit (orange) over the Rio Branco river basin. Forecast of rainfall close to climatology (white) in the northeast, northeast, and south of the monitored region, concentrated on the main course of the Amazon River in Brazilian territory, the Guaporé and Mamoré river basins, the left bank basins of the Amazon River in the northeast of the state of Pará, and Napo.
