中文摘要:
      在自然闪电时,闪电通道中能量的瞬间释放造成闪电冲击波.本文计算了闪电冲击波的运动、冲击波内气象要素的分布以及闪电冲击波对云滴运动的影响,讨论了受闪电冲击波作用的云滴运动方程,对受冲击波作用的云滴运动作了个例计算.计算表明,闪电冲击波猛烈地“冲击”云滴,使它加速并在短暂的瞬间移动很长距离.体积不同的云滴获得不同的速度.讨论了闪电冲击波对云滴碰并增长的影响.
英文摘要:
      Lightning causes the burst of shock wave because cf instantaneous release of energy in the canal. In this paper, the motion of lightning shock wave and its effect on motion of cloud droplets are calculated. The equations of motion of cloud droplets under action of lightning shock wave are discussed. The motions of cloud droplets under the action of lightning shock wave are calculated for some cases. The calculation shows that lightning shock wave strikes the droplets strongly and forces them to move a distance. The droplets with different sizes gain different velocity of motion. The influence of lightning sHock wave on the coalescence growth of droplets is also discussed.
