6) atmospheric acoustic wave
大气声波
1.
According to the results,the over-the-horizon propagation of atmospheric acoustic wave is controlled by the structure of atmospheric wind and temperature,and the acoustic channel is stable.
数值模拟结果表明,大气声波的超视距传播,是大气温度场与风场控制的结果,且这种超视距传播的声信道比较稳定,其反射高度近似在50 km或120km。
