摘要

采用高分辨率的美国中尺度气象非静力模式MM5来模拟珠江三角洲土地利用变化对夏季月气候要素的影响，最高分辨率为3 km。模拟时间段为2005年6月。结果分析表明：模拟的月平均温度和月降水量与实际观测资料符合较好。城市扩展导致珠江三角洲地区尤其是在城市区域月平均地面温度增加，热岛效应增强。在城市扩张和郊区土地利用改变以后，广州、佛山、江门等城市区域降水增加，而东莞、珠海和深圳部分城市区域降水减少。

Abstract

In this study

a mesoscale model (MM5) is used to simulate the impact of land use change on monthly climate in summer over the Pearl River Delta (PRD) region. The simulated period of time is June in 2005. The simulated results show that the simulated monthly average 2m temperature and monthly precipitation correspond to those observed in domain D02. The simulated monthly mean 2m temperature in the PRD increases and a heat island effect become distinctly strong. Due to the urban expansion

the precipitation in Guangzhou

Foshan and Jiangmen increases

whereas the precipitation decreases in Dongguan

Zhuhai and Shenzhen.
