摘要
在高炮人工增雨作业中,作业参数的选择和催化区的分布是一个重要问题。根据梯度输送理论,计算了人工增雨作业中单发和多发炮弹AgI最大扩散半径和时间。以不同AgI浓度阈值模拟分析了湍流扩散系数、方位角、仰角和风速对人工增雨炮弹催化区的影响,依据等角度作业思路,提出了高炮人工增雨迎风半圆多轮作业方案。
One of the important problems in precipitation enhancement with artillery shells is to confirm the parameters of operation and the distribution of catalysis areas. According to the theory of grades transportation,the maximum diffuseness radius and its time are calculated for the single and many artillery shells. The catalysis areas are simulated by using different eddy diffusivity coefficients,azimuths,elevation angles,and wind speed with different AgI concentration thresholds. According to the idea of equality angle,an operation method that cannonballs are shot by repetitious operations within 180° against the wind is proposed.
