| 摘 要： | 根据Cho的研究结果,我们分析了强冰雹过程中不稳定能量演变的一种机制。指出,所谓雹暴天气过程层结能量的积累和释放,可能是层结的能量在z-t平面上非线性传播的结果,积云对流的垂直输送就是波动的传播速度。 资料分析表明,强雹暴天气过程中确实存在不稳定能量的演变。用上述理论所做的数值计算和实际资料很符合。

| Abstract: | In this paper, a mechanism of the evolution of unstable energy in the hail storm is given. It is shown that the evolution of unstable energy may be the result of the nonlinear propagation of energy in z-t plane and that the vertical transport in the cumulus convection is the propagation velocity of the wave.It is shown by the actual observational data that the evolution of unstable energy in a hail storm is in good agreement with the result given by the theory. |
