Outflowing of a high potential vorticity air mass and enhanced convection near South Asia in August 2022
Sortie d'une masse d'air à fort tourbillon potentiel et convection renforcée près de l'Asie du Sud en août 2022
Takemura, Kazuto
In August 2022, high potential vorticity (PV) air masses significantly outflowed near South Asia along the southern periphery of the intensified Tibetan high in the upper troposphere, contributing to enhanced convection near South Asia through intensified thermodynamically unstable conditions. Convective activities near South Asia have relationships with the upper-level PV and the advection over the region. The upper-level northward divergent wind anomalies from South Asia due to the enhanced convection cross the Asian jet, contributing to the intensified Tibetan high. This suggests a feedback process between the intensified Tibetan high and enhanced convection near South Asia through the high PV intrusion.</p>
