The lack of solar particles from the Sun is a sign that this solar minimum is here, and allows more cosmic particles – particles of deep space – to penetrate the Earth. During a solar maximum, the Sun gives away more heat and is sprayed with sun points. Reduced heat in a minimum solar is due to a reduction in magnetic waves. Fewer magnetic waves correspond to the Sun being a little cooler, and experts expect the minimum solar deepening even further before it warms up.
With less magnetic waves coming from the Sun, cosmic rays find it easier to make their way to Earth because they have to fight less solar winds.
Now, with cosmic rays high all the time, scientists know that the Sun is about to start a prolonged cooling period.
And scientists warn that more cosmic particles that hit the Earth can have serious effects on our planet, including air travel and for our climate.
Meteorologist Paul Dorian wrote for Perspecta Weather: “The Sun remains very quiet and has been without sunplaces this year over half the time as we approach what is likely to be be a deep solar minimum.
“One of the natural effects of reducing solar activity is the weakening of the surrounding solar wind and its magnetic field which, in turn, allows more and more cosmic rays to penetrate the solar system.
“The intensification of cosmic rays can have important consequences on things such as the Earth's cloud cover and climate, air passenger safety and as a potential trigger mechanism for lightning.” T
A long and deep minimum solar can also cause temperatures to fall on Earth.
The last time a minimum solar solar was the minimum Maunder, which saw seven decades of icy weather, which began in 1645 and lasted until 1715, and occurred when the sun was very rare.
During this period, global temperatures decreased by 1.3 degrees celsius resulting in shorter seasons and ultimately a shortage of food in what is called a “Little Ice Age”.
Vencore Weather, a meteorological website said: “Low solar activity is known to have consequences on the Earth's climate and climate and is well related to an increase in cosmic rays reaching the upper part of the atmosphere.
“The empty Sun is a sign that the next minimum solar is approaching and there will be an increasing number of endless days over the next few years.”
