This website was developed by PAGASA in collaboration with the Japan Meteorological Agency/Tokyo Climate Centre (JMA/TCC), the World Meteorological Organization (WMO) Regional Climate Centre in RA II (Asia). This one-month (running 10-day) probabilistic forecast product is being produced and updated every Thursday by PAGASA;
-
This product is based on the output of one-month numerical prediction from Global Prediction Center for Long-range Forecast (GPC) Tokyo and the details of its prediction system are available here: ds.data.jma.go.jp/tcc/tcc/products/model/outline/index.html

This sub-seasonal forecast (10-day forecast, but usually weekly or pentad) could provide advance notice of potential hazards related to climate, weather and hydrological events across the country that will eventually support various economic sectors (agriculture, water resource management and others).
Probabilistic Forecast Map
The Subseasonal to Seasonal Forecast
Subseasonal predictions contribute to fill the gap between weather and seasonal time scales.
Objectives:
-
Improve forecast skill and understanding on the subseasonal to seasonal timescale with special emphasis on high-impact weather events.
-
Promote the initiative’s uptake by operational centers and exploitation by the applications community.
-
Capitalize on the expertise of the weather and climate research communities to address issues of importance to the Global Framework for Climate Services.
