The high-speed solar winds stream (HSSWS) generated by coronal hole can produce large interplanetary magnetic field magnitude oscillations. leading to high latitude geomagnetic disturbances. and ionospheric responses as well. This paper has analyzed the global ionospheric total electron content (TEC) and rate of TEC index (ROTI) responses during the high speed solar winds stream occur... https://www.hindigyanvishv.com/
