Earlier this year 'river-effect' snow was reported in the Quad Cities (Western Illinois) along the Mississippi River. Per the local news report:
According to Andy Ervin, a Meteorologist with the National Weather Service, "You need an environment supporting flurries to get saturation for the enhanced snow showers. Air gets channeled between the bluffs and resides over the water at least 45 minutes to pick up the enhanced instability. Thus, you won't see this if winds increase, change direction, or we lose the cold air aloft."
My question is if there are any other reports of this phenomena world wide and has there been any research published?
