Abstract

A preliminary analysis of Global Atmospheric Sampling Program (GASP) data has been made to explore the character of mesoscale atmospheric wavenumber spectra. The results show a K^{— 5/3} spectral slope over spatial scales ranging from about 100 km to about 400—700 km. At larger scales there is evidence of a transition to steeper wavenumber dependence. These results are briefly discussed in terms of two-dimensional stratified turbulence and internal waves.
