Fig.7 Monthly variation of the proportion of plateau vortex days (fTPV), the proportion of extreme precipitation days associated with plateau vortex to the total extreme precipitation days (${f}_{\mathrm{E}\mathrm{X}}^{\mathrm{T}\mathrm{P}\mathrm{V}}$), and the proportion of extreme precipitation days associated with plateau vortex to the plateau vortex days (${f}_{\mathrm{T}\mathrm{P}\mathrm{V}}^{\mathrm{E}\mathrm{X}}$) in the Qinghai-Tibet Plateau region (a) and the Qinghai Plateau region (b) from 1979 to 2021
