HIRLAM, the High Resolution Limited Area Model, is a Numerical Weather Prediction (NWP) forecast system developed by the international HIRLAM programme.


HIRLAM programme is a cooperation between following European meteorological institutes:

In addition, Météo-France (France) is a research partner in the international HIRLAM cooperation.

The Programme[edit]

The aim of the HIRLAM programme is to develop and maintain a numerical short-range weather forecasting system for operational use by the participating institutes. The cooperation was started in September 1985, comprises a series of 3-year project between 1985 and 2005, and 5-year programme HIRLAM-A (2006–2010) and HIRLAM-B (2011–2015). Since 2006, the HIRLAM cooperation has shifted its focus to the development of meso-scale (convection-permitting) numerical weather prediction system (HARMONIE) through close collaboration with ALADIN consortium (led by Meteo France) and ECMWF (European Center for Medium-range Weather Forecasting).

The HIRLAM programme is controlled by the HIRLAM council, which consists of the directors of the participating institutes. The programme is managed by the management group consisting of:

  • Jeanette Onvlee, KNMI, Programme Manager
  • Magnus Lindskog, SMHI, Project leader on data assimilation and use of observations
  • Mariano Hortal, AEMET, Project leader on dynamics
  • Laura Rontu, FMI, Project leader on physics
  • Trond Iversen, met.no, Project leader on probabilistic forecasting
  • Xiaohua Yang, DMI, Project leader on quality assessment and operational cooperation
  • Ulf Andrae, SMHI, Project leader on system
  • Tilly Driesenaar, KNMI, scientific secretary

The management group is advised by a scientific and technical Advisory Committee.
