图6. 1979—2021年全年（a、d）、暖季（b、e）、冷季（c、f）高原低涡极端降水日数占总极端降水日数的比例（${f}_{\mathrm{E}\mathrm{X}}^{\mathrm{T}\mathrm{P}\mathrm{V}}$）（a、b、c）及高原低涡极端降水日数占高原低涡日数的比例（${f}_{\mathrm{T}\mathrm{P}\mathrm{V}}^{\mathrm{E}\mathrm{X}}$）（d、e、f）空间分布（单位：%）

Fig.6. The spatial distribution of the proportion of extreme precipitation days associated with plateau vortex to the total extreme precipitation days (${f}_{\mathrm{E}\mathrm{X}}^{\mathrm{T}\mathrm{P}\mathrm{V}}$) (a, b, c) and the proportion of extreme precipitation days associated with plateau vortex to the plateau vortex days (${f}_{\mathrm{T}\mathrm{P}\mathrm{V}}^{\mathrm{E}\mathrm{X}}$) (d, e, f) for the whole year (a, d), warm season (b, e), and cold season (c, f) from 1979 to 2021 (Unit: %)
