摘要
本文从理论上探讨了南黄海和东海台风潮的动力机制,指出了垂直和平行海岸移行台风均能导致由北向南移行的孤立波;分析了其它一些动力学现象,并以8114号台风引起该海区沿岸实测风暴潮作为例证,结果与实测一致。
Forced waves caused by moving storms are composed of two types of waves(f>0):an isolated wave and an edge wave.Whether the storm is moving normal to the coast or moving parallel to the coast a resurgent isolated wave propagating from north to south can be derived from the storm.1.Storms travelling normal to the coast induce two forms of edge waves:One accompanies the storm wave and has periods relating to 0;the other accompanies the resurgent isolated waves and has periods not relating to θ.When f>0,the periods decrease slightly with increase.2.Storms travelling parallel to the coast induce a form of edge waves,which do not vary with 0 but are affected by a term gaf/V_(0).When f=0,both types of the storm wave induce edge waves with identical periods.
