The international research programme HIRLAM (HIgh Resolution Limited Area Model) is a research cooperation of European meteorological institutes. The aim of the HIRLAM programme is to develop and maintain a numerical short-range weather forecasting system for operational use by the participating meteorological institutes.
The programme was initiated in 1985 and has gone through numerous phases in the past two decades. Since 1 January 2011, the programme has entered a new phase, HIRLAM-B (see the Memorandum Of Understanding HIRLAM-B ). The model which is the focus of HIRLAM-B research activities is the non-hydrostatic convection permitting model HARMONIE. This is being developed in close cooperation with the ALADIN consortium and Météo-France, building on model components that have largely been developed previously in these two communities.

Goals of HIRLAM-B
The main goals of HIRLAM-B are threefold:
- Development of an operationally suitable mesoscale model at a target horizontal resolution of 2.5 km (HARMONIE).
- Development of an operationally suitable short-range multi-model limited area ensemble prediction system, suitable specifically for severe weather (GLAMEPS).
- A new ambition of the cooperation is to develop and deploy cost-effective ways of operational cooperation by means of consortium-wide activities.
The research done to achieve these objectives is described in more detail in the joint HIRLAM-ALADIN rolling work plans for each year of this period (see HIRLAM-B most recent Workplan).
The management group is advised by a Scientific and Technical Advisory Committee, the HAC.
