Abstract
Internal near-inertial oscillations were observed by moored measurements in summer of 1979 in Tokyo Bay. The characteristics of observed oscillations are as follows; 1) The maximum amplitude of oscillations reached to about 8 cm s-1 2) The observed period ranged from 16 to 20 hours, which are shorter than the inertia period in Tokyo Bay; 3) The phase difference of oscillations between the surface and bottom layers is about 180°; 4) The major axis of the oscillations in the northernmost area is directed along the coast. The observed oscillations are explained as the transverse internal seiche in a stratified flat-bottomed channel with straight walls. The characteristics of the observed oscillations are also confirmed by the numerical experiments using the multi-level model with realistic basin and with the time change of wind.
