The spectra of large-scale eddy transfer of angular momentum and heat were constructed for seven levels, ranging from 700 mb to 50 mb over Belmar, N. J., and at the 300-mb and 200-mb levels over Cocoa, Florida. It is found that the frequencies of motion which were largely responsible for the eddy transport of heat shift toward lower frequencies with height. There was no such frequency shift indicated in the case of momentum transfer. The spectral intensity for the transport of angular momentum, when plotted against frequency, in general decreases with increasing frequency. The disturbances of long periods (say, longer than 20 days) were found to play a role as important as those of shorter periods in contributing to the total eddy transport of both heat and momentum.
