| Abstract: | The characteristic quantities describing chaos in respect of correlation dimension, Lyapunov exponents and Kolmogorov entropy are calculeted and analyzed by means of the horizontal wind (u) data observed at Zhangye and Desert stations. Results show that the atmospheric turbulence is a chaotic motion over oasis and desert regions, some conclusions are given and discussed. |
