摘要
本文从大气热力——动力学方程组出发,分析了城市加热作用和摩察作用引起的热岛环流特征,讨论了环流的强度和温度空间分布与背景大气稳定度和平均风速的关系。本文的结果可以解释城市白天的某些气象现象。
In this paper, the heat island circulation induced by the heat source and friction in the urban area in daytime is investigated by using thermodynamic and dynamic equations of atmosphere. The relations among the heat island circulation strength, temperature distribution and the stratification stability, mean wind speed are discussed in detail. Furthermore, some meteorological phenomena in the urban area in daytime can be interpreted by the results are obtained.
