Workshop on Predictability, dynamics and applications research using the TIGGE and S2S ensembles

The TIGGE database consists of medium-range ensemble forecasts from eleven global NWP centres up to 15 days ahead. It started in October 2006 and it has currently reached 3 PiB of data. The S2S database consists of real-time and reforecast outputs from eleven global models producing sub-seasonal to seasonal forecasts up to 60 days ahead. Although the S2S database was established only in 2015,...

CMA's latest progress in the development of S2S Numerical Model database Management and Services Including the following aspects (Xing Hu)：
1. Preprocessing of S2S model data. The original big data files sent by the ECMWF is received and disassembled by preprocessing to be easy for the users to obtain the download.
2. Convenient and flexible data retrieval. Provide online access based on HTTP...

The International Research Institute for Climate and Society Data Library (IRIDL) is a powerful and freely accessible online data repository and analysis web-service that allows a user to view, analyze, and download hundreds of terabytes of climate-related data (including sub-seasonal data) through a standard web browser in a computer or a smartphone. A wide variety of operations, from simple...

An overview of the methodologies for representing initial uncertainties and model uncertainties in the ECMWF ensemble forecasts will be given. Initial uncertainties are represented with perturbations from an ensemble of 4D-Vars with perturbed observations and with perturbations based on singular vectors. Model uncertainties are represented with the Stochastically Perturbed Parametrization...

Since January 2018 DWD runs a global ICON ensemble suite with 40 members and approx. 40km horizontal resolution including a grid refinement for Europe of 20km. Forecasts are generated at 00/12UTC up to +180h and at 06/18UTC up to +120h. To improve the boundary conditions for the COSMO-D2-EPS four additional runs take place at 03/09/15/21 with a limited forecast time of +30h. The ICON-EPS...

The demand for forecast information beyond week-2 has increased significantly in recent years. This information provides valuable guidance for various users who use it to guide public safety, quality of life, and business decisions that drive economic growth. Discussions of predictability, current numerical model capability and applications are greatly enhancing our understanding for...

The Navy Earth System Prediction Capability (ESPC) is a coupled global model consisting of the Navy Global Environmental Model (NAVGEM) atmospheric model coupled to the Global Ocean Forecast System (GOFS), which consists of the Hybrid Coordinate Ocean Model (HYCOM) and the Los Alamos Community Ice Code (CICE). The performance of a 15-member Navy ESPC ensemble during 2017 is compared to coupled...
