How does the solar wind affect Earth's atmosphere?

C426913In summary, the conversation discusses the weight of photons striking the Earth's surface and the effects of the Sun's solar wind on the Martian atmosphere and Earth's atmosphere. The question is posed about whether there are certain times during the day or night when the solar winds are stronger and the possibility of a morning shockwave or a solar vacuum on the night side of the Earth. However, it is determined that the intensity of the solar wind varies greatly and is primarily influenced by solar activity such as sun spots, solar flares, and coronal holes. Coronal holes are the most common source of strong solar wind events.

In the past many of us have read Mr Faraday calculated the “weight” of photon’s striking the surface of the Earth per acre at something like 4 and ½ ounces. Today, frequently we hear stories on the subject of the Sun's solar wind and how it is tearing away the Martian atmosphere and even "stealing" Earth's at an even greater rate. As we idly ponder the phenomena, sucking the flavor of dinner from our teeth and peer up into eternity, I’d like to pose the question, “Are there times during the day (or perhaps even the night I suppose) when the solar winds are stronger?” Is there a morning shockwave as the charged particles and photons strike at an angle on the upper atmosphere and the Earth roles into the wind? Is the power of the solar wind creating something like a morning tidal wave of atmosphere? How high might it be? Is there a type of solar vacuum on the night side as the air is drawn along on both sides of the globe, streaming out behind?

I am a student and Lord help me look forward to at some point investigating this on my own too, but wanted to know what others have come across.

You do understand that the day/night cycle is the effect of the Earth rotation and as such completely irrelevant to the question posted?

If I may add: it is always day somewhere on Earth and night somewhere on Earth.

Hi there PaperAirplane

No

No and no it doesn't have anything to do with photons

No and No

Firstly, the solar wind originates from the upper atmosphere of the Sun. It is a stream of charged particles (plasma) consisting mainly
of protons, electrons and alpha particles ( helium nuclei). The intensity of the solar wind varies greatly both in density and in speed.
The factors are determined by solar activity, primarily, sun spots, solar flares, and coronal holes. The quiet sun solar wind speed
is usually around 300 km/sec, coronal holes can produce wind speeds of around 500 - 800 km/sec. Solar flares can produce wind
speeds of 500 to around 2000 km/sec. Flares produce very large bursts of charged particles from the Sun.
Coronal holes are the most common/regular producers of bursts of strong solar wind events.

What is the solar wind?

The solar wind is a stream of charged particles, mainly protons and electrons, that flow from the Sun into the surrounding space.

How does the solar wind affect Earth's atmosphere?

The solar wind can have a significant impact on Earth's atmosphere. It can cause disturbances in the Earth's magnetic field and result in auroras, or the Northern and Southern Lights. It can also cause changes in the density of the upper atmosphere and affect satellite and radio communications.

What are the different types of solar wind?

There are two types of solar wind: the fast solar wind and the slow solar wind. The fast solar wind originates from coronal holes, which are areas on the Sun's surface with weaker magnetic fields. The slow solar wind is associated with the Sun's equatorial regions and has a lower velocity compared to the fast solar wind.

How does the solar wind interact with Earth's magnetic field?

When the solar wind reaches Earth, it interacts with the planet's magnetic field. The magnetic field deflects the charged particles, causing them to spiral around the Earth. This interaction can create a bow shock in front of the Earth, similar to a sonic boom, and can also cause magnetic storms and auroras.

What are the potential hazards of the solar wind?

The solar wind can pose hazards to Earth's technology and infrastructure. Strong solar winds can disrupt satellite communications, navigation systems, and power grids. They can also pose a radiation risk to astronauts and spacecraft. However, Earth's magnetic field and atmosphere provide protection against most of the harmful effects of the solar wind.
