ON THE DISSIMILARITY BETWEEN HEAT AND MOMENTUM TRANSFER IN THE STABLE ATMOSPHERE NEAR THE GROUND.

Abstract

A fixed layer in the stable atmosphere near the ground shows a remarkable correlation between Delta-u and Delta-Theta when the average Ri number is larger than 0.08. Through the study of time sequences of temperature and wind, evidence of the periodic breakdown of the inversion layer was observed and some interesting aspects of the stable atmosphere were revealed. The effect of the correlation between Delta-u and Delta-Theta on the (K sub H)/(K sub M) was investigated. The (K sub H/K sub M) ratio decreases with height in the stable atmosphere and therefore must be smaller than one. However, it shows an ambiguous behavior with respect to Ri which suggests that Ri is not the only relevant parameter in describing the stable atmosphere. It is evident that the stable atmosphere behaves in a more complex way than the unstable atmosphere and that future work in this area should divorce itself more strongly from the techniques that are being used to describe the unstable atmosphere.
