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.
让全球气象学家如临大敌的原因是,新的5G网络将使用的无线电频率会影响气象卫星对地球观测的关键数据。
Instruments on board the satellites peer down into the atmosphere and study variables such as water vapor, rain, snow, cloud cover and ice content – all crucial factors that influence our weather.
气象卫星所搭载的设备自上而下对大气进行观测,并研究水蒸汽、雨雪、云量和含冰量等变量数据,这些都是影响天气的关键因素。
One example is the 23.8 gigahertz (GHz) frequency. Water vapor emits a faint signal at this specific natural wavelength, 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.
以23.8千兆赫频率为例。水蒸气在这一特定的自然波长发射出微弱信号,这一数据被气象卫星的设备监测并测量到,天气预报员使用这一信息计算出暴风雨或天气系统将如何变化。
“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 capability, weather forecasts will get significantly worse.”
