When the extreme heat in Sun's outermost atmosphere, energises charged particles to the point where they can overcome Sun's gravity, then escape into space.
At this time, solar winds are formed.
This continuous stream of plasma, expands outward to fill the entire solar system.
Magnetic fields in the solar atmosphere play a crucial role in accelerating these particles.
When solar wind reaches earth, our magnetosphere deflects most of it. However some particles leak through near the poles.
These particles collide with atmospheric gases, to create Auroras.
Intense gusts can also create geomagnetic storms which can disrupt satellites and power grids
