%X The turbulent data obtained at the height of 47 m, 120 m, and 280 m at the Beijing 325 m meteorological tower in October-November 1998 have been analysed in this study. The variations of the turbulent statistics with the stability have been investigated. The results show that diurnal variations of the sensible heat flux observed at 47 m is almost the same as that observed at 120 m. It shows that the height of the urban surface layer can be over 100 m due to the large roughness length over the urban surface. At the same time, it is found that the sensible heat flux has a distinct increase when a cold front comes.
