This study explores how ozone–climate interactions affect long-term Arctic stratospheric temperature (AST) changes by isolating the ozone–circulation coupling process. From 1980 to 2000, ozone–climate interactions raise AST in early winter by promoting upward wave propagation and Brewer–Dobson circulation, whereas they decrease AST in late winter and spring by reducing ozone shortwave heating. Our results highlight the impact of ozone–climate interactions on the intraseasonal reversal of AST trends.
