Generating Variable Wind Profiles and Modeling Their Effects on Small-Arms Trajectories

Abstract

It is a common practice in modeling the trajectories of direct-fire munitions to assume that the crosswind is constant across the whole range of the projectiles flight. We know, however, that this is not how wind behaves. Through application of wind variation methodologies and data analysis on the variation of wind versus range, we developed a metric, called Equivalent Constant Crosswind, which allows for the effects of variable crosswind to be modeled without having to explicitly model the variation of the wind at every step.
