摘要
文章探讨了城市对气温等气象要素的影响规律。指出了城市气象是个异于周围农村气象的人工气候岛。例如城市热岛（气温），雨岛（降水量），干岛（相对湿度）等。特殊的城市条件会给城市造成灾害，例如高温灾害，城市洪灾，城市风灾，酸雨，酸雾，光化学烟雾等。城市还有它自己特有的气象现象，如城市热岛环流（乡村风）。城市是地球上的主要大气污染源，在这个人工污染岛中居住。
The effect of city on meteorological elements (for example ,temperature)are investigated.As the urban climates in quite different from countryside,the shape of urban area in meteorological map is like a island clearly.So it is clled artificial climate island.For example,they are:heat island (to temperature),rain island(precipitation),dry island(relative humidity )and so on.Urban climate is so special that it can cause many disasters,such sa high temperature disaster ,rural flood,city gale ,acid rain,acid fog,and photochemicla smog,etc.The city has also its own meteorological phenomenon,like city heatland circulation(country breeze).Citys are the most main origins in the world ,and therefore,it is harmful to health of inhabitant living in the artificial air pollution islands.
