Long-range forecast services (URL and language(s) used). Relevant forecasts, such as forecast for onset/end of rainy/dry season, drought advisory/warning and agrometeorological forecast, are also considered as services concerned.
Methods taken by NMHS to generate long-range forecast products (e.g., model and statistical application). (URLs and language(s) used) if relevant information is provided through the Internet.
JMA operates two types of dynamical numerical ensemble prediction models. One is an atmospheric general circulation model named “Global Ensemble Prediction System” for Early Warning Information on Extreme Weather, Two-week Temperature Forecast, and One-month Forecast. The other is a coupled ocean-atmospheric general circulation model named "Seasonal Ensemble Prediction System" for Three-month and warm/cold season Forecast including El Niño outlooks. Their detailed specifications are on the TCC website at https://ds.data.jma.go.jp/tcc/tcc/products/model/outline/index.html.
In addition, statistical models are also used based on Model Output Statistics (MOS) techniques in generation of forecast products.
Use of climate products provided by other NMHSs or meteorological institutes for long-range forecast
None
III. Climate Monitoring
