| Abstract: | The kinetic energy budget for a developing trough and a shear line over the Qinghai-Xizang Plateau, which occurred respectively in the period from 25 to 28 July 1982 and from 4 to 6 June 1982, had been studied by the diagnostic analysis. The same features are: (1) there is a process of transformation from effective potential energy into kinetic energy, and the maximum value of kinitic energy transformed appears when the trough is developing and extending southwards and the shear line is stabilizing. (2) The kinetic energy is decreased by divergence of the flux of potential energy is most obvious when the trough is developing and the shear line is stabilizing.
The different features are: (1) the value of kinetic energy in shear zone is larger than that in trough zone. (2) The kinetic energy is increased by the term of energy source when the shear line forming, and the kinetic energy is decreased by the term of energy source when the trough developing. |
