A coronal hole is a solar feature that can enhance the solar wind by allowing high-speed solar particles to escape. Such intense solar winds can impact satellites and power grids. Solar park in India projects, such as Bhadla Solar Park, need to take such space weather phenomena into account to safeguard infrastructure and ensure steady energy generation from solar power.
Solar storms, also known as coronal mass ejections, can increase the solar wind and cause disturbances in Earth's magnetosphere. These disturbances can lead to electrical problems, such as power outages and disruptions in communication systems.

The solar phenomenon that wouldn't be expected to increase with an increase in sunspot number is the solar wind speed. Sunspot number correlates with solar activity and can affect phenomena like solar flares and coronal mass ejections, but the solar wind speed is more influenced by other factors like the temperature and density of the solar wind source regions.
Solar flares, coronal mass ejections (CMEs), and coronal holes are solar features that can increase the solar wind. These events release charged particles into space at high speeds, which contribute to the solar wind.
Sunspots themselves do not directly increase the solar wind; rather, they are associated with solar magnetic activity. However, sunspots can lead to increased solar activity, such as solar flares and coronal mass ejections (CMEs), which can enhance the solar wind. During periods of heightened solar activity, the solar wind may become more intense and variable, impacting space weather conditions on Earth.
The Aurora.
The Aurora.
Auroras are caused by solar wind particles interacting with Earth's magnetic field, not solar flares directly. Solar flares can cause an increase in solar wind activity, which can lead to more intense auroras.
You may be thinking of a Coronal Mass Ejection (CME). A chunk of the Sun's outermost layer flies off toward Earth. We had one a couple of weeks ago, producing auroras in parts of the world that are usually too southerly to see them. Also, you may be referring to the closely related phenomenon of "solar flares". Flares are certainly a "solar feature" and are connected with the solar wind.
Auroras are not directly caused by solar flares. Auroras are created when charged particles from the sun, carried by solar wind, interact with the Earth's magnetic field and atmosphere. Solar flares can increase solar wind activity, which in turn can intensify auroras.
The tail of the comets is caused by the solar wind - particles blown away form the Sun. When the comet is closer to the Sun, the solar wind becomes stronger.
