Mapping Southwest Coastal British Columbia Terrain Subject to Extreme Wind Events
|Author(s): Sieben, Brian (Cirrus Environmental Consulting Inc.)||Subject: Climate, Forestry||Series: Forest Investment Account (FIA) - Forest Science Program|
This one year project, a component of a Ph.D. project, will produce maps depicting the modelled estimates of the past 20 years of extreme wind events in the complex landscape of SW coastal BC. Climate stations are few and generally only located at airports and lighthouses, not in the complex terrain where forest managers require site specific wind magnitudes and direction information to make management decisions. This project seeks to overcome inadequate site specific wind information. The Stanford University mass consistent wind prediction model will be used to produce historical predicted wind fields (hindcasts) over the landscape given a digital elevation model and inputs from historical climate data (NCAR/NCEP reanalysis data). The Stanford model will be used to generate 1km predicted (hindcast) winds for storms over the last 20 years that will be input into a GIS for mapping and analysis. Wind roses will be constructed at locations in the landscape to allow the magnitude and direction of the hindcast winds to be displayed for any given point in the landscape. Comparisons will be made to climate station data using wind roses and model verification statistics. Preliminary maps will be produced depicting the frequency and direction of the last 20 years of historical winds in the SW coastal BC landscape.
