Abstract
The forms of the temperature and downwind spectra are examined in the well-mixed and overlying stable layers of the tropical boundary layer. The data were obtained from the tethered balloon system designed for GATE. In the mixed layer, the spectra exhibit an inertial subrange. Preliminary data indicate that a buoyant subrange obeying a −3 power law exists over a range of wavenumbers in the stable layer.
