Other Convergence

Directional Convergence with an Offshore Wind

Directional convergence can also occur with an offshore wind. In this case, wind from the north or north-northeast converges with winds from an east-northeast direction over the lake. Higher elevations on both sides of Lake Superior tend to force the wind to blow parallel to the lake. If the wind veers quickly height to come from the east, snow can be blown back inland over Duluth.
