Abstract: Budgets of divergent and rotational kinetic energy of an intense convection event occurred on March 1st 1983 have been investigated in this part with operational observation data. It has been shown by the results that although the divergent kinetic energy is a small intergant in the total kinetic energy its variations are more closely related to the occurence and the development of the intense convection. Among the three integrants of the energy conversion function {K_D,K_R} between K_D(divergent kinetic energy) and K_R(rotational kinetic energy), term B(-ω∂K_R/∂_P) is the major contributor and term A(-εK·(V_D∧V_R)) is a close second in importance. For the time-area mean, the energy conversion {K_D,K_R} is negative indicating energy conversion from K_D to K_R.
