The urban lovingness island is formed when industrial and urban areas are substantial and heat becomes more abundant.

In cities, where little vegetation and exposed soil exists, the studyity of the suns energy is negligent by urban structures and asphalt. Hence, during warm day set down hours, less evaporative chill system in cities allows surface temperatures to rise higher than in rural areas. Additional city heat is given take out by vehicles and factories, as well as by industrial and dome stic heating and cooling units. At night, the solar energy, which is stored as massive quantities of heat in city buildings and roads, is released slowly into the city. The redundancy of heat energy is slowed and even stopped by the proud building walls that do not allow infrared radioactivity to break as readily as do the sexual relation take aim surfaces of the surrounding countryside.

The slow release of heat tends to keep city temperatures higher than those of the unpaved faster cooling areas. On clear, still nights when the heat island is pronounced, a small thermic low-pressure area forms oer the city. Sometimes a light walkover, called a country breeze which blows from the countryside into the city. If there are maj! or industrial areas along the citys outskirts, pollutants are carried into the heart of town, where they tend to concentrate.
