Many studies presented that solar variability does play a significant role in affecting the Earth’s climate change. Almost all of previous studies focused on the effects of solar total irradiation energy.

As the second major source, the solar wind energy flux exhibits more significant long-term variations, but its effect has been rarely concerned. Although the energy content of solar wind energy flux is of 4-5 orders lower than that of irradiation energy, its long-term variation is much more significant.

For the first time, we find the evidence that the modulation of the solar wind energy flux on the global tropical cyclone activity, and propose a plausible mechanism. We believe this will open a new window to discuss the natural driver of the climate change.

In this study, the global tropical cyclone activity is found to be modulated by solar wind energy flux, but not the solar irradiation and the Earth’s weather and climate parameters. A possible mechanism is proposed and some evidences are also presented.

The findings are helpful to our understanding of solar impact on the Earth’s climate change. More attention on solar wind energy flux is suggested to be paid in the future studies.
