The University of Minnesota (St. Anthony Falls Laboratory and the Department of Mechanical Engineering) team will conduct large-eddy simulations. The primary aim is to complement the field measurements by filling the gaps and to provide data that will help in improving mesoscale models for coastal conditions.
The simulations will use data from field measurements for inflow and local environmental conditions. A realistic land topology will be included in simulations via immersed boundary method, whereas a data assimilation tool will be used to reconstruct the near shore wave field based on the measurements from marine radar and buoys. Using these inputs, the large-eddy simulations will generate detailed flow field description that will help analyze the experimental measurements.
With vastly different topology of the sites chosen (sandy beach, tidal inlet, coastal mountains and urban environments), the CLASI project provides a unique opportunity to study the effect of coastal terrain on the local atmospheric dynamics. We will conduct a parametric study for these sites coupled with different inflow and nearshore wave conditions to identify the key processes that are unique to coastal regions. The data produced by this simulation campaign will help in developing "coastal aware" parameterizations for the mesoscale simulation tool COAMPS.
