| 摘 要： | 根据2004年10月在珠江口西岸新垦观测的大气边界层探测资料和自动气象站资料,研究了珠江口西岸海陆风特征。结果表明:珠江口西岸海风出现频率较高,20时出现频率为51.8%;海风出现和结束时间都较晚,一般在14-18时之间出现,23时-次日02时之间结束;海风环流高度随海风持续时间逐步升高,23时最高达到700 m左右;海风使珠江口西岸贴地逆温出现时间推迟,低空逆温出现频率增加。

| Abstract: | Based on the boundary layer meteorological sounding and automatic meteorological station's data of Xinken on the west coast of the Pearl River mouth in October 2004,the characteristics of the sea-land breeze are studied.The frequency of sea-breeze was high,reaching 51.8% at 20 o'clock.Both the starting and ending time of the sea-breeze were very late.It started from 14 to 18 o'clock and ended from 23 to 02 o'clock of the next day,respectively.The height of sea-breeze circulation rose with the duration of sea-breeze,and reached the peak value of about 700m at 23 o'clock.The sea-breeze delayed the appearance of ground-level inversion,but increased thefrequency of lower-layer inversion. |
