Charles Lin - Regional modelling of the atmosphere

We discuss regional modelling of the atmosphere using a high resolution numerical model (MC2: Mesoscale Compressible Community Model). We present an overview of the model, and results from three applications. They are the study of precipitation from Montreal area storms and comparison with values retrieved from the McGill radar, the surface wind and temperature fields over the Gulf of St. Lawrence and comparison with station observations, and a simulation of the severe precipitation of the Saguenay storm that gave rise to flash floods in the Saguenay region in July 1996.
