What is the impact of solar activity on the terrestrial and cosmic processes

June 24-25, 2016 at the Sun once again there was not a single spot. In the aggregate for the year 2016 – this is already the 6th day, when the Sun has no spots.

For example, in 2011, spots on the Sun was only 2 days. The decrease in the number of sunspots and flares is a clear sign of the approaching of the Sun to the minimum of the 24th cycle of solar activity.

Thus, a reasonable question arises:

What is the influence of variations in solar activity (minimum expected in 2019-2020y) for terrestrial and cosmic processes ?

1. THE BRIGHTNESS OF THE SUN.

Change the brightness of the Sun from minimum to maximum is about 0.1 %.

COMMUNICATION STYLE: POSITIVE

2. The ULTRAVIOLET light.

The luminosity in the ultraviolet spectrum at wavelengths of 200-300 nm changes by approximately 1.5 % from minimum to maximum.

COMMUNICATION STYLE: POSITIVE

3. STRATOSPHERIC NITROGEN.

Change of ultraviolet light in the positive direction at maximum leads to the formation of more ozone in the stratosphere, while during the maximum amount of ozone in the stratosphere is reduced.

COMMUNICATION STYLE: POSITIVE

4. WARMING OF THE STRATOSPHERE

The greater quantity of ozone, the stratosphere becomes warmer and Vice versa.

Temperature changes in the stratosphere leads to a shift of the tropospheric and stratospheric atmospheric currents towards the poles of the Earth.

These processes probably weaken the Western transfer system “ocean – land” in the troposphere, which can cause colder winters in Europe (see the Maunder Minimum of 17-18 century).

COMMUNICATION STYLE: POSITIVE

5. GEOMAGNETIC ACTIVITY

While the minimum decreases not only the number of spots, coronal holes and solar flares, but the number and intensity of magnetic storms, while at the time of the maximum of the number and intensity of magnetic storms is greatly increased.

COMMUNICATION STYLE: POSITIVE

6. SOLAR WIND

During the maximum increase is observed in the solar wind (stream of particles from the Sun, mostly protons) and their density.

Colliding at high speed with the Earth’s magnetic field it causes an intense Aurora.

At the time of low frequency and intensity of auroras is reduced as a result of the weakening of the intensity of the solar wind.

COMMUNICATION STYLE: POSITIVE

7. COSMIC RAYS

Amplification of the solar wind leads to a weakening of the influence of cosmic rays on the planet at maximum and to strengthen it during a minimum.

In turn, increased cosmic radiation during a minimum increases the distance at which it can permeate, for example, it is known that during solar minimum, increasing the radiation dose civil aircraft.

TYPE OF COMMUNICATION: NEGATIVE

8. CLOUD

It is assumed that cosmic radiation affects the amount of aerosols in the atmosphere, which play the role of condensation nuclei in the formation of clouds. The overall impact on the level of the Earth’s albedo is about 1.5-2 %.

9 RADIATION LEVEL

During the low radiation level in the upper atmosphere increases, while the maximum decreases.

COMMUNICATION STYLE: POSITIVE

10 ICE

The amount of carbon-14 in ice and plants, beryllium-10 and chlorine -36 in polar ice shows a negative relationship depending on the magnitude of solar activity and a positive correlation depending on the magnitude of cosmic radiation.

TYPE OF COMMUNICATION: NEGATIVE

11. HELIOSPHERE

The more active the Sun, the greater the radius of the heliosphere (region of space near the sun where the solar wind plasma is moving relative to the Sun at supersonic speed.)

COMMUNICATION STYLE: POSITIVE
