摘要
利用2010年7月～8月在广东碣石湾地区的近海和远海两个观测点的小球探测气象资料,分析研究碣石湾地区夏季污染大气边界层特征。结果表明,该地区夏季以东南风和西南风为主导风向,观测期间出现了海陆风、热内边界层现象,但出现频率均较低,因此对大气扩散影响不大。混合层高度统计发现,内陆观测点混合层高度略高于近海观测点。
Based on meteorological data of two observation sites, inland and seaside of Guangdong Jieshi Bay area during July to August 2010, characteristic of planet boundary layer in summer was analyzed. The results indicated that the domain wind direction was SE and SW in Jieshi Bay area in summer. Sea- land breeze and thermal internal boundary layer phenomenon was observed during the test, with less effect on atmospheric dif- fusion; through statistics of the mixed layer height it was found that mixed layer height on the inland observa- tion point is slightly above the offshore observation point.
