The superimposed distribution pattern of a moving sprinkling lateral is not equal to that of a solid set employing the same sprinklers, whenever wind variations occur between positions of the lateral. Variations perpendicular to the lateral have the most significant effect, resulting in convergence or divergence of two adjacent patterns. The uniformity coefficient increases (improves) and the mean depth of water increases with increased convergence. The effect on the uniformity coefficient is more pronounced as the spacing between lateral positions increases. For every wind regime there is an optimum direction of the laterals for which the overall uniformity is highest.
