| 摘 要： | 利用2008年10月15日—11月16日在广州从化获得的基线小球测风资料,分析研究了秋季从化山谷风的特征。研究表明:从化山谷风主要出现在系统风速小于1.5 m/s,谷风出现时间为10:00—18:00,山风强度比谷风强度大;山谷风厚度大致为300 m,回流出现高度在300～700 m;山谷风转换期间,静小风频率较高;系统风与山谷风方向相反时,山谷风高度内多为静小风。冷锋过境时不会出现山谷风。

| Abstract: | Based on the baseline pilot balloon data observed during October 15th to November 16th in 2008, the characteristics of mountain-valley breeze in Conghua, Guangzhou are analyzed. It was found that the mountain-valley breeze is significant when the system wind is weaker than 1.5 m/s. The valley breeze prevailed at local time from 10:00 to 18:00 when it was weaker than mountain breeze. The thickness of mountain-valley breeze was about 300 m while the return-flow appeared between 300 and 700 m. The frequency of calm wind was higher during the period of mountain-valley wind transformation. While the direction of the weaker system wind was opposite to the mountain-valley wind, the wind speed was calm or smaller within the height of the mountain-valley breeze. When a cold front passed by, there was no mountain-valley breeze. |
