In general, the heat gathered from the urban heat island effect rises and travels upwards and its energy may change high-altitude currents in the atmosphere that dictate prevailing weather. Meteorologists have known that cities are warmer than rural areas with cars, buildings, asphalt and roofs that absorb heat.… Read More
