The solar minimum "deep" is there and could cause weather forecasts for CHAOS and GEL trips | Science | New

A lack of solar particles from the Sun is a sign that the solar minimum is there and that it allows more cosmic particles – particles of deep space – to enter the Earth. During maximum sunlight, the sun gives off more heat and is covered with sunspots. Less heat in a solar minimum is due to a decrease in magnetic waves. Fewer magnetic waves means the sun is slightly colder, and experts expect the solar minimum to deepen further before it warms up.

With less magnetic waves coming from the Sun, cosmic rays have a better chance of making their way to Earth because they have to fight against fewer solar winds.

Now, with cosmic rays at a record high, scientists know that the Sun is about to enter a prolonged cooling period.

And scientists warn that more cosmic particles hitting the Earth can have serious impacts on our planet, including air travel and our climate.

Meteorologist Paul Dorian wrote for Perspecta Weather: "The sun continues to be very calm and it does not have sunspots this year more than half the time, as we approach what will probably be a deep solar minimum. .

"One of the natural impacts of the decrease in solar activity is the weakening of the ambient solar wind and its magnetic field, which allows more and more cosmic rays to enter the solar system.

"The intensification of cosmic rays can have important consequences on aspects such as cloud cover and the Earth's climate, the safety of air travelers and as a possible trigger mechanism for lightning."

A long and deep solar minimum can also cause a drop in temperatures on Earth.

The last time that a prolonged solar minimum was in effect was the Maunder Minimum, which experienced seven decades of freezing cold. It began in 1645 and extended until 1715, and occurred when sunspots were extremely rare.

During this period, temperatures fell overall by 1.3 degrees Celsius, resulting in shorter seasons and, ultimately, food shortages in what was called a "mini ice age" .

Vencore Weather, a weather web site, said, "Low solar activity is known to have an impact on the weather and climate of the Earth and is also correlated with an increase in cosmic rays that reach the upper part of the Earth. 'atmosphere.

"The virgin sun indicates that the next solar minimum is approaching and that there will be more and more days without spot in the next few years."
