1, the solar wind is a high-temperature and high-speed charged particle ejected from the surface of the sun at a speed of 300-700 kilometers per second. The detection method can be quantitatively detected by radiometer and particle counter on space satellite, or indirectly measured by observing the X-ray radiation intensity of charged particle flow through X-ray telescope.
2. Similar X-ray observation can be made on the ground, but the ground observation is inaccurate and invalid because the atmospheric ionosphere absorbs X-rays. Due to the protection of geomagnetism, the solar wind particle flow cannot be directly detected in most areas on the ground, but when the solar wind is strong, the aurora produced by the interaction between the particle flow and the atmosphere can be seen near the poles of the earth.
In addition, geomagnetic storm is a sudden change phenomenon of geomagnetic field, including sudden increase and sudden decrease. At the same time, the solar wind can easily lead to large geomagnetic storms. But the two can't be equated, because geomagnetism is also influenced by the activities inside the earth, the revolution position of the moon, cosmic rays and so on. The intensity of solar wind and geomagnetic field are not linearly corresponding.
Well, the answer you adopted is wrong. How can the solar wind be equal to a magnetic storm?
You asked how to detect the solar wind, and I explained it. The previous answer was wrong, and I also analyzed it. .
All right. If you still think my answer is copied from the internet, I have nothing to complain about. .
