Abstract Using orthonormal wavelet transform, We made analysis of experimental data of convective boundary layer turbulence in water tank, including multi‐scale decomposition and high frequency noise removing. Spectrum analyses show that turbulence in mixed layer is very different from that in entrainment zone. This difference may be caused by various characteristics of large scale element in turbulence. While the small scale turbulence in both mixed layer and entrainment zone are similar, which are homogeneous and their spectra are satisfied with Kolmogorov's scaling law with –5/3 exponent.
