论文摘要
极端的天气事件在强大的太阳能电场的间隔内发生。奇怪的是，在这些时间间隔内，它们对地球反应措施的影响（例如极地盖指数）不如预期的那么高。理论家对这种饱和效应提出了许多解释，但没有共识。在这里，我们表明饱和仅仅是太阳风测量中的不确定性所产生的感知，尤其是在测量时间。纠正不确定性表明，极端空间天气事件的影响比以前想象的要大约300％。此外，它们指出了与任何相关研究相关的一般结果：测量时间的不确定性会导致系统的线性响应被视为非线性。
Extreme space weather events occur during intervals of strong solar wind electric fields. Curiously during these intervals, their impact on measures of the Earth's response, like the polar cap index, is not as high as expected. Theorists have put forward a host of explanations for this saturation effect, but there is no consensus. Here we show that the saturation is merely a perception created by uncertainty in the solar wind measurements, especially in the measurement times. Correcting for the uncertainty reveals that extreme space weather events elicit a ~300% larger impact than previously thought. Furthermore, they point to a surprisingly general result relevant to any correlation study: uncertainty in the measurement time can cause a system's linear response to be perceived as non-linear.
