摘要
本文根据基本关系式及海上风和波浪的实测资料,统计计算了珠江口以西陆架海域的风漂流和斯托克斯漂流,并对其分布、变化特征进行了分析讨论。
The wind-induced drift may be divided into two parts. One is drift and the other is stokes drift. According to the essential formula and observations of wind and wave, we statistically calculate the drift and stokes drift on the sea surface in this paper. The results show :(1) the main vector direction of wind-induced drift is near-southwest, it's velocity on the sea surface is about 21—27 cm/s in winter monsoon period, and it is near-north and near-northeast, it's velocity is about 12—20cm/s in summer monsoon period; (2) the drift current velocity is about 2.2 percentage of the wind velocity, and the stokes drift velocity is about 1 percentage of the wind velocity; (3) the largest velocity of the stokes drift will be over 100 cm/s only in summer; but the highes velocity of the drift is not over 100 cm/s in the year round; (4) the stokes drift velocity decreases with depth taster than the drift, it will dissappear over 20 m, but the drift velocity is about 10 percentage of the surface velocity above the "friction depth".
