Effect of Geomagnetic Storms on Space Weather during the Ascending Phase of Solar Cycle 24

C. M. Tiwari, Devendra Gautam, Manish Kumar Parsai & Sandeep Kumar Tiwari · Physical Science International Journal · 2026

Space weather disturbances are significantly influenced by geomagnetic storms, which arise from intensified solar wind-magnetosphere coupling. This study examines the correlative dynamics of solar activity indicators (Sunspot Number, F10.7 index), interplanetary parameters (solar...

Space Weather Conditions Associated with Highly Perturbed Interplanetary Conditions and the Heliospheric Relaxation Phase During Solar Cycle 24

C.M. Tiwari, Lokesh Ojha, Manish Kumar Parsai, Jayshree Pandey, Devendra Gautam, Achyut Pandey & Sandeep Kumar Tiwari · Asian Journal of Physical and Chemical Sciences · 2026

Space weather conditions are strongly influenced by variations in interplanetary parameters and Solar Cycle (SC) dynamics. SC 24 exhibited distinct phases of heliospheric relaxation and highly perturbed interplanetary conditions, providing a unique framework for analysis. Underst...
