The Sun cycle connects to the global climate
The maximum activity of the Sun and its results have an effect on the Earth like La Nina and El Nino in the tropical region of the Pacific.
The study found an important link between the global solar and climate cycles led by scientists from the NSF (National Science Foundation) showing that the Sun's maximum activity and its results are The effects on Earth are similar to La Nina and El Nino in the tropical region of the Pacific .
This study could pave the way for temperature predictions as well as weather patterns at certain times in the Sun's 11-year cycle.
" The results are surprising in that they show a series of scientifically connected events with the Sun's cycle with ENSO, the Pacific tropical phenomenon that strongly affects the climate change in the world, "said Jay Fein, program director at NSF's campus. " The next step is to confirm the results of this sample or continue to conduct new analyzes and observations ."
The total energy to Earth from the Sun varies by 0.1% during the Sun cycle. Scientists have been searching for decades to connect these changes to natural weather, climate change and to distinguish unrecognizable influences from the larger types of global warming due to human cause.
Based on previous research, researchers have used computer models for global climate and ocean temperatures for more than a century to answer conundrums about the connection between solar activity. and global climate.
" We have just discovered the effects of a new mechanism to find out what is happening in the Pacific Ocean when the Sun's maximum activity occurs ," Gerld Meehl said. " When the Sun's activities peak, there will be far-reaching effects, but often less attention is paid to the weather systems around the world ."

Along with an earlier study by Meehl and colleagues, it was shown that, when the Sun was at its peak, it could make the cloudless parts of the Pacific hot enough to increase evaporation and enhance Tropical rain and tropical Pacific trade and cooling winds.
The result of this phenomenon is similar to a La Nina phenomenon although the temperature drop from 1 to 2 degrees Faranei is concentrated in the Far East and only half as strong as a typical La Nina phenomenon.
In the next 1 or 2 years, La Nina-like weather patterns are enhanced by the Sun's maximum activity that will tend to evolve to an El Nino-like pattern, where the slow-moving ocean currents replace Cool ocean currents in the eastern tropical Pacific with warmer water than usual.
La Nina and El Nino are related to changes in the surface temperature of the water in the Eastern Pacific. They can affect global climate. More research is needed to determine the effects of these events on the world climate.
Scientists know, long-term solar changes affect certain types of weather, including drought and regional temperatures . But the establishment of a real communication between the solar cycle and global climate is still difficult.
One reason is that in the last few years, new computer models have been able to simulate the actual processes involved in the warming of the Pacific tropics and the cold associated with El Nino and La Nina.
With these models in hand, scientists can reconstruct the Sun's activity over the past century.
