About this research group
The Environmental Flow Group simulates, analyses and evaluates a wide range of fluid flows, with an emphasis on the atmosphere and ocean at local scales. Applications include dispersive transports, and fluid-structure interactions associated with human activities.
The Group has projects in offshore renewables, weather prediction, CO2 storage and aquaculture. It currently comprises nine staff, with international backgrounds in meteorology, oceanography, geophysics, physics, mathematics and engineering. Positions range from doctoral to professorial, and are situated at the University of Bergen as well as Uni Research Computing, at the Geophysical Institute, Bjerknes Centre for Climate Research and the Department of Mathematics.
The Group collaborates with others at and allied with Uni Research: the Climate Predictions and Regional Scenarios Group at the Bjerknes Centre for Climate Research, the Geosciences Group at Uni Research CIPR and, at Uni Research Environment, SAM-Marin and the Laboratory for Freshwater Ecology and Inland Fisheries.
The Group’s mesoscale atmospheric model of choice is the Weather Research and Forecasting (WRF) model. This is a newly-developed next-generation model, supported by a world-wide community (www.wrf-model.org).
- It is freely distributable.
- The US National Centre for Atmospheric Research (NCAR) continuously develops and maintains the code, along with the US National Centre for Environmental Prediction (NCEP).
- In applications addressed by the Group, the model is typically forced at start-up and at domain boundaries using global reanalysis or forecast data from the European Centre for Medium-Range Weather Forecasts (ECMWF).
The Group’s surface-wave model of choice is from the international Wave Modelling group (WAM), or a variant of this for Simulating Waves Near-Shore (SWAN). The latter is a third-generation spectral model that takes account of the local generation of waves by wind and their dispersion and refraction as a result of depth variations and tidal currents (www.swan.tudelft.nl).
- The US Office of Naval Research (ONR) develops and maintains the code, along with the Dutch water-management agency, Rijkswaterstaat.
- In applications addressed by the Group, the model is typically forced at start-up and at open domain boundaries using global reanalysis or forecast data from a global implementation of WAM, as managed by ECMWF.
The Group’s ocean model of choice is the Bergen Ocean Model (BOM). It is a fully non-hydrostatic model, developed in-house, in collaboration with the Mathematics Institute at the University of Bergen (www.mi.uib.no/BOM).
- In applications addressed by the Group BOM is typically forced at start-up and at open domain boundaries using analysis data supplied by MyOcean (www.myocean.eu).
