NASA Confirms Rainy Cities

Devil's BSD writes: "It's true, urban areas are rainier than rural areas. Using the Tropical Rainfall Measuring Mission satelite to measure rainfall around cities, NASA found that areas downwind from cities had up to 116% more precipitation than those upwind from it. The cause? The major heat difference, up to about 10 degrees Fahrenheit (5.6 Celsius degrees), caused by the asphalt and concrete in cities.
