Abstract
Tibetan Plateau vortices (TPVs) are important rainfall producers over the Tibetan Plateau in summer and can also influence wide areas east of the Tibetan Plateau when emigrating from the plateau. The Effects of the variations in air temperature over the Tibetan Plateau on the genesis frequency of TPVs at interannual timescales is explored in this work to understand the interannual variations in TPVs and the resultant precipitation. The results indicate that the interannual variations in the genesis frequency of TPVs are significantly related to that in the air temperature at 250 hPa over the Tibetan Plateau. The upper-level air temperature affects the genesis of TPVs by modulating the large-scale circulations at 200 hPa. In warm (cold) years, an anomalous high (low) at 200 hPa is observed over the eastern Tibetan Plateau and central China, and a strong (weak) westerly jet is found north of the Tibetan Plateau. The upper-level westerly jet is considered to have a direct influence on TPVs. Impact of 250-hPa air temperature over the Tibetan Plateau on the westerly jet is further explained from two perspectives. First, the air temperature at 250 hPa regulates the thermal wind between 250 and 200 hPa, thereby affecting the wind at 200 hPa. Second, the air temperature at 250 hPa changes the geopotential height gradient at 200 hPa north of the Tibetan Plateau, which results in variations in the westerly jet there. Consequently, more TPVs are generated over the Tibetan Plateau in warm years, and vice versa for cold years.
