EXPLORATORY ESTIMATES OF THE EFFECT OF RAIN ON ARTILLERY FIRE
Abstract
This exploratory investigation is only a preliminary step in deciding whether a correction of an indirect artillery fire for rain, and for the presence of clouds along a trajectory of the projectile need be considered. The study attempts only a rough estimate of the possible range of the results of a more thorough investigation. An example, based on the max range of the 105mm howitzer and a mildly heavy rain is given. Only one novel coefficient has been computed: this is the usually-neglected effect of the vertical wind. It is tentatively concluded that the principal effect of rain is the theoreticallymeasurable meteorological effects of the saturation of air with water vapor. Outside of these, the rain may have a significant effect only if it is very heavy, and extends over a large segment of the trajectory of the projectile. (Author)
