wave duct การใช้

After the storm move in shandong area , the moist downdrafts appears , the mgws apart from the thunderstorm and move faster , the mgws weaken gradually because absence of wave duct and energy supply
The result can be long distance reception of radio waves that would normally have been far beyond the radio horizon . the equations for ray tracing were given , simulating and tracing electro - magnetic wave duct propagation using spherical layered atmosphere mode , this method is very useful for analysis of radar echo distribution and confirm relation of stratification of atmosphere and ray duct propagation in the process of studying radar second product , introduce a new 3 - d interpolation method . outcome of this method can suit all kinds of density product
