FURTHER ANALYSIS OF WINDSOC DATA

Abstract

The Windsoc program demonstrated that material released from an elevated source was transported to the ground readily by vertical mixing under most of the conditions encountered during the program. Principal limitations occurred during conditions of light or moderately light geostrophic (pressure gradient) winds. In this case the total energy of motion is small and only small amounts of turbulent energy become available to carry out the vertical mixing. The principal effect of the low level wind jet on vertical mixing is to maintain a greater degree of turbulence throughout the night when nocturnal cooling near the ground would otherwise be expected to reduce the mixing. The ultimate result is that portions of the night under low level jet conditions become highly favorable for mixing to the ground from an elevated release. (Author)
