The sudden compression of the air caused by a projectile in passing close to another body
{i} deflection of wind; adjustment made to allow for wind deflection; side of ship turned towards the wind; friction between a moving object and the air
the deflection of a projectile resulting from the effects of wind exposure to the wind (as the exposed part of a vessel's hull which is responsible for wind resistance) bore-to-projectile difference in diameter the retarding force of air friction on a moving object
