In the second Tibetan Plateau Experiment(TIPEX), from west to east, three stations of atmospheric boundary layer observation were set at GAIZE, DANGXIONG, and CHANGDU. Synchronous observations in three stations were carried out for more than 40 days from June 1998 to July 1998. That was the first experiment held in the Tibetan Plateau from west to east to observe the structure of the boundary layer and the turbulent transfer process in the surface layer in different location synchronously. Many observational data were obtained about the structure of the plateau boundary layer and the turbulence in the surface layer.
In this paper, the data of the meteorological elements in the surface have been analyzed which were obtained during the IOP of TIPEX from May to July 1998 in Gaize, Dangxiong and Changdu observation stations of the plateau. The characteristics of the diurnal variations and the vertical profiles of the wind speed, temperature and humidity in the surface layer have been investigated. Some interesting results have been obtained. The moisture inversion phenomena in the surface layer have been discussed also.
Keywords: the diurnal variations of the meteorological elements, the vertical profile,
