WebON THE GENERATION OF WAVES BY WIND 455 It is convenient to remove the gravitational body force from the y*-momentum equation by introducing a modified pressure such that Ji* = P*-P2gY* PA - P* -pigy*. (2.2) This transformation causes the gravitational effects to appear explicitly in the interface con- ditions. WebAddThis Utility Frame. Uncorrected OCR. Machine-generated text.
