It is experienced when certain pockets within a city experience higher heat than neighboring areas in suburban or rural areas, on the same day. The temperature variation can range between 3 to 5 degrees Celsius. Urban-rural temperature differences are often largest during calm, clear evenings. This is because rural areas cool off faster at night than cities.<\/p>\n<p>There are following factors that give rise to the phenomenon of Urban Heat Island:<\/p>\n<ul>\n<li>Transpiration is a natural way of heat regulation. But the urban areas <strong>lack sufficient green cover<\/strong> or gardens.<\/li>\n<li>The <strong>tall buildings<\/strong> within many urban areas provide multiple surfaces for the reflection and absorption of sunlight. This is called \u201curban canyon effect\u201d.<\/li>\n<li>tall buildings also block the wind, which inhibits cooling by convection and prevents pollutants from dissipating. <strong>Waste heat<\/strong> from automobiles, air conditioning, industry, and other sources also contributes to the UHI.<\/li>\n<li>Cities usually have buildings constructed with glass, bricks, cement, and concrete- all of which are <strong>dark-colored materials<\/strong>, meaning they attract and absorb higher heat content. Thus, it forms temporary islands within cities where the heat remains trapped.<\/li>\n<li>The <strong>haze of air pollution<\/strong> that hangs over many cities can act as a miniature greenhouse layer, preventing outgoing thermal radiation (heat) from escaping from urban areas.<\/li>\n<\/ul>\n<p><strong>Way forward:<\/strong><\/p>\n<ul>\n<li>Trees, green roofs and\u3000vegetation can help reduce urban heat island effects by shading building surfaces, deflecting radiation from the sun and releasing moisture into the atmosphere.<\/li>\n<li>Other ways of heat mitigation include appropriate choice of construction materials, promoting terrace and kitchen gardens and painting light colours on terraces to reflect heat.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Introduction: explain urban heat island effect.
