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。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.
