Abstract
A harmonic analysis of the observed diurnal variation of the coefficient of eddy viscosity is conducted at selected levels followed by a mathematical analysis of the amplitude coefficients in order to determine a function of height and time needed to represent this variation. It is found by this approach that a lengthy series of terms, consisting of exponential and polynomial functions of height and trigonometric functions of time and height, would be needed to represent the observed variation.
A two layer empirical model is developed from the observed data which gives the coefficient of eddy viscosity as a function of stability and height in the lower layer, and as a function of vertical shear of the horizontal wind and height in the upper layer.
The author wishes to express his appreciation for the assistance and encouragement of Professors G.J. Haltiner and A.B. Mewborn of the U.S. Naval Postgraduate School in this investigation.
