%X Using orthonormal wavelet transform, we make an analysis to experimental data of convective boundary layer turbulence in water tank, including multi-scale decomposition and high frequency noise removing. Spectrum analysis shows that turbulence in the mixed layer is very different from that in the entrainment zone. This difference may be caused by various characteristics of large scale elements in turbulence. While the small scale turbulence in both the mixed layer and the entrainment zone are similar, they are homogeneous and their spectra are satisfied with the Kolmogorov's -5/3 exponent law.
