The main aim of the Project is to contribute to build very high-resolution ensemble systems in Europe, resolving the convection-permitting scale phenomena.

The main objectives are to:

A. Develop new products and methodologies for calibration of LAM ensembles for extremes and probabilistic prediction of thunderstorms and fog:

1) Inventory of existing methods and SW already developed by the Members and literature review;

2) Define and develop new products and methodologies for computation/elaboration:

· calibration of ensembles, mainly for extremes (wind, precipitation, temperature,…);

· products for probabilistic prediction of thunderstorms (clear benefit, link with research, link with EMMA), fog.

B. Understanding the sensitivity of ensemble prediction systems to soil conditions and PBL and their effect on the prediction of selected phenomena (fog and thunderstorms)

1)      Investigating sensitivity of models to soil moisture and PBL;

2) Investigating the ratio of sensitivity to different sources of surface and upper air uncertainty at the CP scale.

The requirements

The content of the requirements for the EUMETNET SRNWP-EPS Phase II (EPS-II) has a main aim: to contribute to build very high-resolution ensemble systems in Europe, resolving the convection-permitting scale phenomena. To reach this aim, the usual coordination within C-SRNWP was not enough, since dedicated meetings should be organized, where status and plans of the participants are revised and where an agreement on the ground for cooperation should be found.

The main open issues for scientific research on this subject are outlined and described in the document: “Explore the scientific methodologies suitable to build a very high-resolution ensemble” which is the Delivery 3 of the Phase I SRNWP-EPS Activity; the document was prepared by the Expert Team on EPS of the EUMETNET C-SRNWP Program. The aim of this document is to provide scientific and methodological basis for planning future work on the field; it includes a scope of topics larger than those covered by the phase II requirements. 

These requirements will help to identify few tasks which can be accomplished within a limited amount of time and with a dedicated amount of resources, leading to clear and tangible outcomes such as coexistence of both operational and (focused) research activities, in order to satisfy the different needs of the NMSs. Therefore, the topics which have been identified for this Phase II requirements focus on all-the-steps-towards-the-development of a methodology for the probabilistic prediction of severe weather phenomena (e.g. thunderstorms and fog), relevant for the operational duties of the NMSs.

The SRNWP (Short Range Numerical Weather Prediction) Working Group was established in 1993 on the basis of the already existing EWGLAM (European Working Group on Limited Area Modelling) network. Since that time the SRNWP project is the main vehicle for the cooperation between the European limited area modelling consortia (the main developing entities of short range numerical weather prediction models). These numerical weather prediction consortia are the ALADIN, COSMO, HIRLAM, LACE projects and the UK Met Office. The C-SRNWP (“C” stands for the coordination) Project has been working under the EUMETNET project since 2000.


  • "high resolution numerical models"

The tasks

– Enhance SRNWP related information and knowledge exchange between members

– Represent the interests of short-range NWP in front of other organizations (e.g EUMETNET Observation Projects, ECMWF, etc.)

– Popularize European NWP systems in education

The requirements

The main aim of the C-SRNWP Programme is to foster the efficient exchange of information between the Project Participating Members and across the European limited area modelling consortia related to scientific, technical as well as operational aspects of NWP. The main vehicle of this information exchange is the yearly EWGLAM/SRNWP Meeting, the scientific program of which is compiled by the C-SRNWP Programme Manager and the Expert Teams of the Programme.


The C-SRNWP Programme is also playing a coordinating role between the European LAM NWP community and other EUMETNET projects, particularly with EUCOS on observation impact studies, with OPERA on the possible re-distribution of radar volume data for data assimilation purposes and with EMMA on the best exploitation of NWP products for severe weather warnings. An evident collaboration is also taking place with the ASIST and EPS-II Projects.


The Programme is responsible for an intensified collaboration with ECMWF (participation as observer on the ECMWF Scientific Advisory Committee) and EUMETSAT, and promotes contacts with non-European NM(H)S’s and institutions.

The organisation

The current phase of the C-SRNWP Project started in January 2013 and will last until end of 2018. The Project Coordinating Member is the Hungarian Meteorological Service. The Project Manager is Mr Balazs Szintai from the OMSZ.

The inter-consortia cooperation is stimulated by a part-time coordinator (Project Manager) and realised within the activities of the Expert Teams (ET).

The following Expert Teams (they were created at the beginning of 2008) are acting in the framework of the C-SRNWP Project:

– Data assimilation and use of observations (mailing list: etda(at)met.hu)
– Diagnostics, validation and verification (mailing list: etverif(at)met.hu)
– Dynamics and lateral boundary coupling (mailing list: etdyn(at)met.hu)
– Link with applications (mailing list: etapp(at).met.hu)
– Physical parameterisation (upper air) (mailing list: etphys(at).met.hu)
– Predictability and EPS (mailing list: eteps(at).met.hu)
– Surface and soil processes (mailing list: etsfc(at)met.hu)
– System aspects (mailing list: etsystem(at)met.hu)
– SRNWP Advisory Expert Team (NWP Consortia leaders and chairs of the above Expert Teams)

The activities under the SRNWP Project and the work of the Project Manager is supervised by the SRNWP Advisory Expert Team.

Traditionally the entire SRNWP group meets once per year (early autumn), where the annual “business” meeting is held in conjunction with the annual EWGLAM meeting.
More details about the Project can be found on the C-SRNWP webpage.

Summary of 2nd European Nowcasting Conference

3-5 May 2017
DWD, Offenbach

The 2nd European Nowcasting Conference (ENC), organised under the umbrella of the EUMETNET nowcasting project ASIST, was held at the headquarters of DWD in Offenbach, Germany, from 3 to 5 May 2017. Close to 100 participants from 24 nations presented their latest findings on observations, nowcasting techniques, verification, user aspect and combined nowcasting/numerical weather prediction. Besides the many excellent presentations, there was plenty of room for discussions during dedicated time slots at the end of each session as well as during poster sessions and coffee breaks.


To a large extent, observation and nowcasting techniques dedicated to convective phenomena were presented, indicating that thunderstorms and lightning are still one of the major themes in nowcasting. Furthermore, it could be noted that, even at individual national meteorological services (NMS), a wide variety of nowcasting systems and models are available which can lead to an overwhelming (and sometimes inconsistent) suit of nowcasting information available for forecasters. It is thus not surprising, that efforts towards seamless prediction systems, incorporating a multitude of nowcasting and NWP models, can be noted.  While nowcasting is still tied to observations and their short-term extrapolation, the combination of nowcasting with NWP is gaining momentum as NWP systems with rapid update cycling are approaching the nowcasting domain.


While the conference gave an impressive view of the many efforts in nowcasting techniques, there currently still seems to be a lack of coordinated activities. Similar systems are developed in parallel at different research institutes or NMS’s and one might ask if a coordination of those efforts could be fruitful and result in widely accepted and applied nowcasting tools. Modelling consortia, such as those for NWP’s, are not yet existent for nowcasting. Possibly, such cooperation is difficult due to regional and observation specific characteristics as well as the end-user focused nature of nowcasting . In this heterogeneous and interdisciplinary setting, it is important that the EUMETNET nowcasting project ASIST continues to support the cooperation between nowcasting researchers and practitioners among NMS’s.
