Numerical study of atmospheric winds, small scale wind potential and wind transformation against the coast of the Gaspésie area

Period of execution: March 2001

Customer's name: Ministry of Natural Resources of Quebec's research funding.

Summary:

This project intends to adapt a hydrodynamic model using the finite elements method, to simulate wind and small scale wind potential. In order to show the model's performance, a study of wind transformation against the coast will be conducted in the Rimouski area. The model will use wind recordings carried out by the MRN with four weather towers laid out at the river's edge and with other data available to fix the model boundary conditions and validate the results.

Principal activities carried out:

• Adaptation of a hydrodynamic layer model for atmospheric wind modeling;
• Construction of a calculation meshing used for the validation of the modifications made to the digital model;
• Development of a method that will allow the boundary conditions to be treated in a suitable way;
• Construction of a calculation meshing based on the topographical data of the Sainte-Félicité area;
• Realization of simulations reproducing real wind conditions on Sainte-Félicité's sector;
• Comparison of the model's results with wind observations from four weather towers established in Sainte-Félicité's sector;
• Construction of a calculation meshing based on the topographical data of the Rimouski area;
• Realization of simulations reproducing wind conditions against the coast of Rimouski's sector;
• Comparison of the model's results with wind observations from three weather towers established in Rimouski's sector;
