Weather Tidbits: Urban Heat Island Effect

This Weather Tidbits describes what is the urban heat island effect. The urban heat island effect is explained through heat emitted from cars, buildings & factories which will bump temperatures up. Other factors include asphalt and dark rooftops retaining heat; along with concrete reducing surface moisture. Lastly, less trees means less shade which also means less cooling from evapotranspiration. This explains why rural and rural farmlands are the coolest areas; while downtowns tend to be the warmest up to 10°, at times with all the buildings & concretes. Commercial & urban residential areas tend to be the 2nd and 3rd warmest areas; while the coolest place in an urban location will be a park. Suburban areas could be considered halfway points of temperatures from urban to rural locations.
