Long-term variation in the solar terrestrial enviroment related to solar cycle
Abstract
It is known that the solar activity fluctuates in a cycle of about 11 years, and the global magnetic field structure of the sun changes with the fluctuation. This change in the magnetic field structure has a great effect on the solar wind from the sun into the interplanetary space, and as a result, the solar terrestrial environment also fluctuates in a cycle of about 11 years. In this research, we will stochastically discuss what the solar wind will look like in about 10 years by combining the following solar cycle activity prediction model and the solar wind model that we have developed so far. In this research, we will combine the next solar cycle activity prediction model and the solar wind model that we have been developing so far, and probabilistically discuss what the solar wind will look like about 10 years from now. In addition, we will verify whether the coronal hole generation, transportation, and disappearance on a time scale of several tens of days and the solar wind in the earth's orbit can be reproduced by our method using past observation results.
