| 摘 要： | In this paper,the data chosen from measurements by supersonic anemometers in Tongxian County of Beijing in1990 are used to study characteristics of turbulence spectra in precipitation weather.Some turbulence parameters such asturbulence intensity,heat and momentum fluxes,friction velocity,M-O length and stability parameter are calculatedand their dependence on turbulence spectra in different stability conditions are analyzed.Some encouraging results areobtained and compared with others' results.
