This sunspot number forms the basis for the Solar Cycle Progression, where we move from Solar Minimum, a period of relative calm with few sunspots, to Solar Maximum, a time of heightened magnetic activity. This process is driven by the motion of electrically conductive plasma, primarily composed of ionized hydrogen and helium.
Investigating the Drivers Behind the Solar Cycle's Rhythmic Patterns
Convection and Differential Rotation Inside the Sun, energy travels outward from the core through radiative zones and finally reaches the convective zone. The heliospheric current sheet, a vast surface separating regions of opposite magnetic polarity, also warps and undulates more severely as the cycle progresses, influencing the entire heliosphere.
This modulated solar wind helps shield the inner solar system from a portion of galactic cosmic rays, high-energy particles originating from outside our solar system. During solar maximum, the Sun is riddled with these spots, leading to increased solar flares and coronal mass ejections.
Investigating the Solar Cycle Causes: Plasma Motion and Magnetic Field Dynamics
This turbulent convective motion drags the Sun's magnetic field lines along for the ride. Here, hot plasma rises like a boiling fluid, cools near the surface, and then sinks back down to be reheated.
More About What causes the solar cycle
Looking at What causes the solar cycle from another angle can help expand the discussion and give readers a second clear paragraph under the same section.
More perspective on What causes the solar cycle can make the topic easier to follow by connecting earlier points with a few simple takeaways.
