HIROMB
HIROMB (High Resolution Operational Model for the Baltic Sea) is the ocean circulation model used operationally at SMHI. HIROMB forecasts sea level, currents, salinity, temperature, ice thickness, ice concentration and ice drift. HIROMB covers the entire Baltic and North Sea as far west as the English Channel, with resolutions varying from 900 metres to 3 nautical miles (about 5.5 km).
HYPNE
The HYPNE (Hybrid Parametrical Shallow Water Nested) wave model is a second generation wave model used by SMHI for wave forecasting. The model covers the North Sea and the entire Baltic.
HIRLAM
HIRLAM (High Resolution Limited Area Modelling System) is the main tool used for short term weather forecasts (up to 48 h) at SMHI. The model covers the whole of northern Europe and the North Atlantic. The results from HIRLAM are used as input data for HIROMB and HYPNE.
Research and development: SCOBI; HIROMB, PROBE & RCO
SMHI’s oceanographic research department principally focuses on developing four models: HIROMB, SCOBI, (Swedish Coastal and Ocean Biogeochemical) and PROBE (Program for Boundary Layers in the Environment). SCOBI is a biogeochemical model and PROBE is a one-dimensional model for calculating currents, temperature and salinity in the water column.
