44th EWGLAM & 29th SRNWP workshop


The 44th European Working Group on Limited-Area Modelling (EWGLAM) Meeting and the 29th Short Range NWP (SRNWP) Meeting were successfully organized between 26-29 September in Brussels, Belgium, with around 80 in-situ and 60 online participants and several invited speakers. The special topic this year was “Opportunities and challenges in hectometric NWP”. It was concluded that many hectometric NWP applications nowadays are focusing on urban environment. The most important challenges related to these models are adequate external parameters (e.g. land use database on the order of 10 m) and suitable physical parameterizations (e.g. 3D turbulence). A special session was also organized about the future evolution of High Performance Computing.

Presentations are available at the meeting’s website: http://srnwp.met.hu/Annual_Meetings/2022/index.html





EMMA (European Multi service Meteorological Awareness) and the Meteoalarm web page represent one of the most successful and visible achievements of EUMETNET. EMMA has improved national and European multi-hazard warning systems over the last decade by developing standards, and has deepened the cooperation with partners like civil protection, the DRR community and the water sector. Meteoalarm has been operational since 2007 and the website has generated large public interest.

The objectives of EMMA are:

  • To show the most relevant information on Meteoalarm needed to prepare for extreme weather and related hazards expected to occur somewhere over Europe.
  • Provision of warnings understandable by all actors from the private and public sector. Warnings are multilingual and harmonized as far as possible, whereas the four level color code is seen as understandable “language“.
  • The Meteoalarm web page provides a one-stop shop and a repository for multi-hazard warnings.
  • Research and Development: harmonization of the warnings towards impact oriented warnings.
  • Support of the regional cross-border collaboration between forecasters.
  • Networking and coordination with relevant organizations like Civil Protection Organizations and ERCC the Emergency Response and Coordination Centre of the European Commission
  • EMMA provides the basis for knowledge transfer to other regions and the service delivery improvement of developing weather services.
  • “We travel more frequently, either on business or privately, and the exposure to risks abroad is greater than at home. Meteoalarm integrates all important severe weather information over Europe originating from the official National Public Weather Services across all participating European countries - ensuring that information is presented consistently to allow for coherent interpretation as widely as possible, with easy accessibility across languages and culture.”

The tasks

Collection and online publication of the authoritative warning information for meteorological and hydrological hazards delivered by 37 (as of 2018) National Meteorological and Hydrological Services (NMHSs) in 33 languages across the European domain for the next 48 hours.

Consistent presentation of the information to ensure coherent interpretation as widely as possible throughout Europe.

Technical quality control of the incoming messages and display of this information on maps with European, national and regional levels.

Operation of Meteoalarm as one-stop shop and a repository for relevant multi-hazard warnings to be used e.g. by professionals or tourists on a European scale. Re-user are able to acquire warning data from RSS and CAP (Common Alert Protocol) feeds or alternatively the alert hub.

Harmonization of the warnings as much as national procedures allow any adaptation with thresholds based on climatologically chosen regions and impact considerations.

Provision of a platform for meteorologists and hydrologists to discuss a consistent and harmonized system of warnings across Europe.

Comprehensive relaunch of Meteoalarm. The modernization and redesign of the whole system with improved functionality will give Meteoalarm a contemporary professional on-line presence, thus enhance the visibility of EUMETNET and the participating members and improve the accessibility of their authoritative warnings.


The organisation

The current phase of EMMA started in January 2019 and will last until the end of 2023. The Coordinating Member is ZAMG (Austria). The Programme Manager is Rainer Kaltenberger. The EMMA Team is advised by the Meteoalarm Expert Group

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 tasks

The project workload is divided into several work packages and then into tasks.

The complete list of tasks can be found here.


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.

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.
