Overview

The Working Group on Subseasonal to Interdecadal Prediction (WGSIP) aims to develop a programme of numerical experimentation for seasonal-to-interannual variability and predictability, with an emphasis on assessing and improving predictions. Research goals are to develop appropriate data assimilation, model initialization and forecasting procedures for subseasonal-to-interdecadal predictions, with consideration of factors such as observing system evaluation, use of ensemble and probabilistic methods, statistical and empirical enhancements, and measures of forecast skill.

  • Develop appropriate data assimilation, model initialization and forecasting procedures for subseasonal-to-interdecadal predictions, considering such factors as observing system evaluation, use of ensemble and probabilistic methods, statistical and empirical enhancements, and measures of forecast skill
  • Report to the WCRP Joint Scientific Committee on the status of subseasonal-to-interdecadal forecasting, and liaise with the WCRP Working Group on Coupled Modelling (WGCM) and the JSC/CAS Working Group on Numerical Experimentation (WGNE)

NOTE: In 2017 the The Working Group on Seasonal to Interannual Prediction (WGSIP) changed its name to the Working Group on Subseasonal to Interdecadal Prediction (WGSIP). Where you see the older name used, it is to preserve the name as used in pre-2017 projects.
