Outline TIGGE Global Model output Tropical cyclones TIGGE LAM What next ? 4th PDEF Tokyo 9-12 Oct 2018

TIGGE: THORPEX Interactive Grand Global Ensemble Ensemble forecast data from ten global NWP centres, starting from October 2006, which has been made available for scientific research. TIGGE was established as a key component of THORPEX: a World Weather Research Programme to accelerate the improvements in the accuracy of 1-day to 2 week high-impact weather forecasts for the benefit of humanity. THORPEX programme finished at the end of 2014, TIGGE will continue for a further 5 years, when its future will be reviewed. 4th PDEF Tokyo 9-12 Oct 2018

Since last PDEF meeting July 2017 The situation was critical for a while Not secured human resources in my team Many actions delayed (eg, user survey) as time was spent on re-establishing contacts with Data Providers, filling gaps and migrating from unsupported hardware NCMRWF fully supported Many data gaps filled (NCEP, ECCC, CMA) All contacts with Data Providers re- established 4th PDEF Tokyo 9-12 Oct 2018

TIGGE: continue ? More additions: DWD Icon-EPS re-instate BoM ? High resolution (deterministic) forecasts ? ECMWF, NCAR and CMA happy to continue with TIGGE activities 4th PDEF Tokyo 9-12 Oct 2018

Suggested next steps Get strong motivation to continue with TIGGE From PDEF and other WGs Issue a user survey https://confluence.ecmwf.int/display/TIGGE/TIGGE+survey Write to TIGGE Data Providers (by WMO) obtain their commitment to continue with TIGGE for another 5 years (2019-2023), aligned with 2nd phase of S2S and WWRP Implementation plan (2016-2023) TIGGE-S2S workshop April 2019 4th PDEF Tokyo 9-12 Oct 2018
