Abstract : Frontal systems in the United States and Western Europe were examined in detail to determine the variation in density across the fronts. The significance of these changes was considered, taking into account the accuracies of measurement and weapons. Using zone density as a criterion, it was found that warm fronts are not at all significant ballistically; and most cold fronts only marginally. In contrast, a squall line or thunderstorm is accompanied by large, short-lived density variations that could, if ignored, lead to excessive range errors in artillery firings. (Author)
