The introduction of 5G mobile phone networks could seriously affect weather forecasters’ ability to predict major storms.
 
移動5G網絡的應用可能會嚴重影響暴風雨預報的準確性。
 
That is the stark1 warning of meteorologists around the world, who say the next-generation wireless2 system now being rolled out across the globe is likely to disrupt the delicate satellite instruments they use to monitor changes in the atmosphere.
 
The result will be impaired3 forecasts, poorer warnings about major storms, and loss of life, they say.
 
"The way 5G is being introduced could seriously compromise our ability to forecast major storms," said Tony McNally of the European Centre for Medium-Range Weather Forecasts in Reading. "In the end it could make the difference between life and death. We are very concerned about this."
 
The crisis facing the world’s meteorologists stems from the fact that the radio frequencies the new 5G networks will use could contaminate critical Earth observations made by weather satellites.
 
Instruments on board the satellites peer down into the atmosphere and study variables such as water vapor4, rain, snow, cloud cover and ice content – all crucial factors that influence our weather.
 
One example is the 23.8 gigahertz (GHz) frequency. Water vapor emits a faint signal at this specific natural wavelength5, and this data is monitored and measured by weather satellites. Forecasters then use this information to work out how a storm or weather system is likely to develop.
 
"Such data is critical to our ability to make forecasts," said Niels Bormann, also of the Reading weather centre. "They are a unique natural resource, and if we lose this capability6, weather forecasts will get significantly worse."
