Wind Farms in Iowa

The National Weather Service Radar at Des Moines, Iowa shows some of the wind farms located in Iowa. The radar beam gradually rises higher above the ground as it travels away from the radar. The radar shows more or fewer wind farms depending upon the atmospheric conditions. The radar beam is bent downward toward the Earth. Sometimes the bend downwards allows more wind farms to be picked up by the radar beam. At other times only wind farms closer to the radar are visible compared with this evening. Sometimes almost none of the wind farms are visible.
