Abstract:

The XM76 Grid is a new testing location for smoke munitions where terrain and meteorological tower influences on meteorological measurements have not been previously analyzed. The primary objective is to quantify site influences on wind and turbulence data collected at the XM76 Grid. A secondary objective is to evaluate the capability of Smith and Turner stability categories to order turbulence data. Sigma ASigma E ratios are used to quantify terrain influences at low and high wind speeds for fetches over low, moderate, and high roughness terrain. Tower shadowing effects on wind and turbulence measurements are also quantified as a function of wind speed. Preliminary analysis of Smith versus Turner stability category techniques indicates superiority of the Smith technique for the horizontal component of turbulence.
