Furthermore, the responses of SC to global warming often exhibit a mixture of varying intensity and shifting location, such as the intensified and westward shifting North Atlantic subtropical high in boreal summer (Fig.

22. Considering the center and intensity of background SC seasonally vary, we cannot choose a domain that is suitable for all seasons and distinguish the changes in intensity and location. Due to the mixture of these factors, we did not obtain a robust projection on global SC changes.
