Operational short-range Limited Area Models (LAM) in Europe are mostly being developed by consortia of collaborating National Meteorological Services (NMS’s). HIRLAM (High Resolution Limited Area Model) was the first of these consortia on limited area modelling in Europe, established in 1985 in the Nordic countries and later extended with other members. he HIRLAM collaboration has originally been organized in Projects and there have been 6 of these (from HIRLAM-1 to HIRLAM-6). The members then decided to continue the collaboration in the form of five year programmes, HIRLAM-A (2006-2010), HIRLAM-B (2010-2015), Memorandum Of Understanding HIRLAM-B, External review) and HIRLAM-C (2016-2020).
HIRLAM's long-term goal
HIRLAM’s prime long-term goal is to provide its members with a state-of-the-art operational short and very short range numerical weather prediction system, and the expertise associated with it. The main application for the NWP system is the production of operational weather forecasts for the member services, with particular emphasis on the detection and forecasting of severe weather and services related to public safety.
HIRLAM and ALADIN
In 2005, the strategic decision was made for HIRLAM to engage in a close code cooperation with the ALADIN consortium. The aim of this research collaboration is to develop and maintain a common, state-of-the-art mesoscale LAM model code for short-range numerical weather prediction, within the code framework of the ECMWF/Arpege Integrated Forecasting System (IFS). This common mesoscale analysis and forecasting system, which within HIRLAM is called HARMONIE, is intended to eventually replace the HIRLAM model in all of its applications.
The terms of the HIRLAM-ALADIN collaboration have been formalized in the HIRLAM-ALADIN Collaboration Agreement, adopted in December 2014. The two consortia have agreed to work together with the aim of forming a single consortium at the latest by the end of 2020.
The HIRLAM-ALADIN collaboration will be continued in the HIRLAM-C programme.
The primary purpose of the HIRLAM-C programme is to carry out research and development together with ALADIN partners in order to provide the members with a comprehensive mesoscale NWP system as the best suitable means of support for their operational short-range weather forecasting activities. Most of this work is carried out in close coordination with the ALADIN programme under well-aligned scientific work plans.
