atmospheric refraction

English	Chinese
An increase in air temperature causes an increase in the speed of sound, which means that in these conditions airblast emissions can be focused back toward the ground by atmospheric refraction	大气温度的增高、促使声速增加、这是说在这些条件下、大气折射可将冲击波挡回到地面
atmospheric refraction model	大气折射模型
Real-time data from a predictive meteorological model and sounding equipment is input to an atmospheric refraction model that enables the effect of meteorology on airblast levels in the area surrounding the blast site to be evaluated	从预测大气模型和测声设备中获得的数据输人到大气折射模型、从而能评价气象对爆炸现场周边区域内的冲击波能级的影响
