In this paper,the method for determining the direction and velocity of internal tide wave is proposed.The main points are as follows:(1) starting with the continuity equation of incompressible fluid and taking the isotherm whose balance position is situated in the middle of the thermocline as the interface of two-layer ocean,one can get an equation of variations of average total current in the lower and upper layers; (2) WTide (Z) in the above-mentioned equation is expressed in first-order approximation; (3) the internal tide waves are treated as wave packets.Thus,one finds out a statistical relation,AΔū + BΔū=ζ,which correlates the average shear effect caused by the internal tide wave with the isothermal fluctuation.The direction and velocity of the wave can be drawn from the formulae:φ1=Arctg (A/B),C1=1/(H0·√A2+B2). The calculated results agree,in the main,fairly well with two sets of observations at station L3.
