By analysing the wind data observed by radiosonde during 2000-2002 in Wuhan, zonal and meridional wind velocity, wind shear and energy were discussed. A winter maximum and a summer minimum of the zonal wind velocity which pace up and down between the height of 10-15km was found. The weaker variation of the meridional wind reflects the seasonal variation of gravity wave activity in the lower atmosphere. The energy variation show a trend stronger in winter and spring then in other seasons. A winter maximum and a summer minimum in the troposphere and lower stratosphere was also found, which ranged in similar height range as wind velocity. As a result, a strong correlation between horizontal wind velocity and kinetic energy can be infered.
