Abstract

AbstractThe Laverton Serial Sounding Experiment provided a comprehensive sounding of the atmosphere over a period of one month in the southern Spring of 1966. These data have been analysed to determine the variations of fluxes of mass and horizontal momentum at heights from 2 to 28 km, and the contributions to these fluxes by the mean flow and transient eddies. The co‐spectrum functions of the fluxes were evaluated to obtain contributions to them by eddies of different sizes. The partitioning of the Reynolds stresses (momentum fluxes) by various frequencies is examined for the existence of a ‘spectral gap’ and it is concluded that no definite gap exists in the frequency range examined. A strong quasi‐diurnal mass flux is found in the lower troposphere.
