Impact of urbanization on meteorological factors in Pearl River Delta |
|
|
Abstract Impact of different urbanization stages (primitive, rapid and stable) on the temperature, wind speed and wind direction in the five rapid urbanization cities (Zhuhai, Zhongshan, Dongguan, Guangzhou, Shenzhen) of Pearl River Delta (PRD) was studied with the running mean and Mann-Kendall statistical significance test of 1973~2008 observations at five weather stations. It was found that the temperature changing rates were positively proportional to the urbanization increasing rates while both the changing rates of wind speed and the frequency of dominant wind direction were negatively proportional to the urbanization increasing rates. These results had been visualized as conceptual curves in the present paper.
