Rod Heelis: As the societal technology increases, more and more of that technology becomes dependent on communications that use space-based transmitters and receivers.
That's space scientist Rod Heelis. Heelis told EarthSky that the clarity of satellite radio and GPS signals depends on the current state of the ionosphere – the uppermost part of Earth's [-----1-----].
Rod Heelis: So if the ionosphere is smooth, then the signals will pass through the ionosphere relatively unimpeded and there'll be a clear signal on the ground. If the ionosphere is [-----2-----], then those signals can be distorted or completely removed from passing through the ionosphere so you don't get any communication or navigation at all.
Heelis used special instruments aboard a space weather satellite to measure the size, density and movement of ionospheric particles. Heelis hopes to predict these [-----3-----] spots – called 'space storms' – in the ionosphere.
Rod Heelis: One way to think about these storms in space is to think about them as [-----4-----] or hurricanes, and that is, there's not much you can do about them. [-----5-----]

If you could forecast when and where they will be, then you can arrange to not be in that location so that you can avoid the impacts of them.
GPA：global positioning system
troposphere對(duì)流層
stratosphere【氣】同溫層, 平流層，最上層, 最高檔, 最高部位
mesosphere【氣】中圈, 中層, 散逸層(離地250哩以上)
thermosphere 熱電離層(80公里以上的高空的電離層)

1. atmosphere 大氣
2. disturbed： emotionally upset, troubled, or maladjusted
3. turbulent： adj：being in a state of turbulence，wild or insubordinate; unruly
4. tornadoes 龍卷風(fēng) 旋風(fēng)
5. If you could forecast when and where they will be, then you can arrange to not be in that location and so you can avoid the impacts of them. 如果可以提前知道具體位置，就可以提前做好防護(hù)工作。
