一、引言内波,如果按其周期划分,可以分成短周期内波和潮周期(长周期)内波两类。前者的典型周期介于5—10分钟之间,后者的典型周期约为12小时或24小时。潮周期的内波又叫内潮。这种内波大多数发现于近岸水域。例如 Reid(1956)和 Ce-rsola(1967)在加里福尼亚近海,Keunecke(1971—1972)在挪威的陆坡均发现过这种内潮。通常认为,这种内潮是层化海洋中,主要由于潮流和急剧起伏的海底地形之间的相 I. INTRODUCTION The internal waves, if divided according to their periods, can be divided into two types within the short-period wave and the tidal period (long period). The former typically has a period of between 5-10 minutes, the latter typically having a period of about 12 hours or 24 hours. The tidal cycle of the wave is also called the tide. Most of these waves are found in inshore waters. Such as the Reid (1956) and Ce-rsola (1967) off the coast of California, Keunecke (1971-1972) in Norway’s slope were found in this kind of internal tide. It is generally assumed that this internal tide is a stratified ocean, mainly due to the phase between the tidal current and the sharply fluctuating seafloor topography
