| Abstract: | By using turbulence data obtained from the atmospheric boundary layer,thecharacteristic quantities describing chaos in respect of power spectra,correlation dimen-sion,Lyapunov exponents and Kolmogorov entropy are calculated and analyzed. Resultsshow that the atmospheric turbulence is a chaotic motion and possess strange attractorsin phase space,and a deterministic nonlinear differential equation with at least 7-8 or-ders (or 7-8 variables) for holding the strange attractors in phase space is needed to de-scribe the turbulence. |
