Meiyu rainfall in June–July of 2020 hit the Yangtze‐Huaihe River basin, and the precipitation at lots of observational stations broke the records, inducing severe disasters there. Tibetan Plateau vortices (TPVs) generated over the Tibetan Plateau are local major rainfall triggers. In previous knowledge, TPVs can affect the rainfall in eastern China, only after emigrating from the Tibetan Plateau. In this work, roles of TPVs in the record Meiyu are revealed, implying that the effects of TPVs may be underestimated previously. Firstly, TPVs dying out over the Tibetan Plateau may be transformed into troughs and continue to move eastward, influencing the rainfall in Yangtze‐Huaihe River basin. Secondly, southwest vortices, the important rainfall producers in China, tend to be generated and maintained when TPVs are located over eastern plateau. The results give extended knowledge on the effects of TPVs, which are beneficial for the rainfall prediction in eastern China. This is a timely work revealing roles of the Tibetan Plateau vortices (TPVs) in the record Meiyu in 2020, implying that effects of TPVs are underestimated previously. After the TPVs disappear, troughs transformed from the TPVs continue to move eastward and affect Meiyu rainfall in Yangtze‐Huaihe River basin. Additionally, TPVs greatly contribute to the genesis and maintenance of the important rainfall producers in Meiyu‐southwest vortices.Figure shows time‐longitude sections of 6‐hourly precipitation (shadings; unit: mm), and positive vertical vorticity at 500?hPa (pink contours; unit: 10~(?5)s~(?1)). Locations and trajectories of the TPVs are represented by green dots and green lines, respectively. The black line indicates 104°E, which is the easternmost longitude of the Tibetan Plateau.
