The motion of Automous Underwater Vehicle (AUV) changes obviously when it sails near surface under the influence of ocean waves, so it is difficult to sustain the depth.

According to the characteristic explosion of the vehicle bombs, the parameters of air shock wave in the vehicle bombs explosion near the surface are calculated in this paper.

Wind shear near the surface, for design purpose, is a shear which ACTS on a space vehicle free-standing on the pad or at the time of lift-off.
