摘要
海洋同大气间相互作用的研究，近年来，在许多科学技术比较先进的国家，已经成为地球物理学的中心课题之一．开展这一研究，不仅有助于了解气侯的形成及其变迁，以求改进全球天气预报模式，而且它同海洋天气及水文要素的数值预报、海洋开发与海洋污染、航海及水声学等科学实践息息相关。
During May and June of 1978, two runs of measurments of mean wind speed, temperature and humidity profiles in the first 5. 2 m of marine atmosphere were made in Tiaozhou Bay near Qingdao. Based on the obtained data, the vertical distribution characteristics of the mean wind speed, temperature and humidity were analysed. The calculated results lead to the following main conclusious : when the wind is not greater than Beaufort scale 5, the magnitude of the sea surface roughness Zo ranges from 0.001 cm to 1 cm, the friction velocity U(?) increases with wind speed at the reference level (9m), and the bulk drag coefficient CD ( at 9 m ) is independent of wind speed, its typical value is about 2.0×10-3.
