The Urban Heat Island Effect

Te urban heat effect is a well-documented phenomene where urban areas experimence signitantly highantly highmatures than surfaces insidunging rural or natural landscapes. In Phoenix, this effect is specilarly pronounced. Studies indicate that urban surfaces absorb and store solar energy during the day and distaase it slow ly after sunset, creating a dome of elevated temporates that can be 5- 10 ° F (3o6 ° C) hotter thalbene desert.
