ATMOSPHERIC TURBULENCE INTENSITY AND DIFFUSION PARAMETER OVER COMPLICATED TOPOGRAPHY OF EASTERN GUANGDONG

Based on observations by a dual-theodolite anemometer tracking balanced balloons and an American Gill UVW anemograph for complicated underlying surface in Meizhou, eastern Guangdong, turbulent fluctuations of the Lagrangian and Eulerian systems are determined for the area. Following the Taylor formular in respect to a few reference frames, horizontal and vertical turbulence intensity and atmospheric diffusion parameters σy and σx are then computed and compared with those obtained by the PG method and BNL experiments. It is found that within heights less than 100 m above the ground σy and σx are larger than values of PG and BNL with all conditions of stability and stratification.
