Title: Another Look at Turbulence Parameterization at the Bottom of the 
Atmosphere
Abstract:
By analyzing the Cooperative Atmosphere-Surface Exchange Study in 1999 
(CASES-99), turbulence at a given height is found to be dominant by 
large eddies under near neutral conditions. These large eddies scale 
with the observation height and are closely related to the bulk shear 
between the ground and the observation height. The relationship between 
turbulence strength, local shear, and the bulk shear suggests a new way 
to parameterize turbulence at the bottom of the atmosphere.
