| Abstract: | We analyzed the data measured by three axes propeller anemometers at 10 and 75 m level at coastal Guangdong, with the statistical turbulent theory. The atmospheric diffusion parameters were studied. The results indicate that, in the coastal region, the horizontal turbulence was controlled by large scale eddies and the vertical turbulence was controlled by relatively small scale eddies. There was an obvious change in diffusion parameters when the sea and land breezes changed their direction from sea to land or vice versa. The change in lower layer was more significant than that in the upper layer. |
