城市热岛效应对昆明市降雨量的影响分析

Influence Analysis of Urban Heat Island Effect on Rainfall in Kunming City

针对城市热岛效应日趋明显且影响气候环境变化的问题,以昆明市为例,基于雨量站长系列实测短历时暴雨资料,定性定量分析了城市热岛效应对降雨量的影响程度。结果表明,城市热岛效应对降雨有一定影响,但不足以改变资料系列的一致性,可为研究城市暴雨特性、防洪和未来城市热岛效应方向提供参考。

Urban heat island effect becomes more evident and has impact on the climate and environment.According to long series measured rainfall data with short duration of Kunming City,this article analyzes the effect of urban heat island on rainfall qualitatively and quantitatively.The results indicate that the urban heat island effect has some influence on rainfall;but its impact does not change the consistency of data series,which provides references for studies of urban storm characteristics,the future direction of urban heat island effect and urban flood control.
