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.”
雷丁天气中心的尼尔斯-铂尔曼说:“这种数据对我们预报天气的能力非常关键。它们是独特的自然资源,如果我们失去了这种预报能力,天气预报会准确性将极大降低。”
