Quick Answer
Dominant wind directions in the Midwest for siting are generally from the southwest through west, with some variation by state and region. This is due to the prevailing wind patterns in the area, which are influenced by the Rocky Mountains to the west and the Great Plains to the south.
Understanding Wind Patterns in the Midwest
The Midwest region experiences a continental climate, with strong winds during the winter months. In this region, the prevailing wind direction is from the southwest through west, with an average speed of 7-10 mph. This is due to the high pressure system that dominates the region during the winter months, resulting in a pressure gradient that drives winds from the west.
Determining the Best Siting Location
To determine the best siting location for a wind turbine in the Midwest, it’s essential to assess the local wind patterns. This can be done by using data from nearby weather stations or by conducting a site assessment. The ideal location will typically have a clear path for the wind to travel, with minimal obstructions such as trees or buildings. A good rule of thumb is to look for areas with a fetch of at least 1-2 miles, where the wind can travel without being blocked.
Siting Considerations for the Midwest
When siting a wind turbine in the Midwest, it’s also essential to consider the local terrain and topography. Hills and ridges can create turbulence and reduce wind speeds, while valleys and low-lying areas can experience strong winds. A site with a gentle slope and a clear path for the wind to travel will typically offer the best results. Additionally, it’s essential to assess the site for any potential noise or visual impacts, as well as any local regulations or zoning restrictions.
