The terahertz band characteristic attenuation rate in 6G mobile communication system is studied. Through the model building and simulation, the results show that 6G radio wave fluctuates greatly with the increase of frequency in dry air, and there are multiple peaks. The characteristic attenuation rate of radio wave in water vapor at low frequency band is smaller than that in dry air, and adverse at high frequency band. The results also show that the characteristic attenuation rate increases with the increasement of rainfall, and is faster than that of frequency. The characteristic attenuation rate has little effect on the visibility. For frequency above 150GHz, the characteristic attenuation rate is greatly affected by snowfall intensity, while the frequency below 150GHz is relatively less affected by snowfall intensity. Under the frequency band of 20GHz, the characteristic attenuation rate increases obviously with the increase of frequency, and the characteristic attenuation rate is relatively gentle with the increase of frequency when it is above 20GHz. Meanwhile, the change is not obvious with the water content in the dust. For a certain water content, frequency from 0 to 350 GHz and temperature from 0 to 60 °C, the characteristic attenuation rate mainly increases with the increase of frequency, almost does not change with temperature.
