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.
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 wind occurs when charged particles, primarily electrons and protons, are ejected from the sun's outer layer, the corona. This phenomenon happens continuously, but its intensity can increase during solar events like coronal mass ejections or solar flares. The solar wind travels through space and can interact with planetary atmospheres and magnetic fields, influencing space weather.
It is solar wind
When solar flares increase solar wind from the corona, they can cause stunning displays of light in Earth's upper atmosphere known as auroras. These phenomena, commonly referred to as the Northern and Southern Lights (Aurora Borealis and Aurora Australis), occur when charged particles from the solar wind interact with Earth's magnetic field and atmosphere. This interaction creates vibrant, rippling sheets of light that can appear in various colors, primarily green, pink, and purple.

The Sola or Sun.
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.
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.
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.
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.
