Thunderstorm development is not always dependent on atmospheric physics alone. Often, the surrounding landscape can influence convection, especially in regions with dramatic elevation changes. The Yangtze river basin in China’s Jiangxi Province, which is surrounded by the Nanling Mountains, often experiences mesoscale convective systems (MCS) or squall line thunderstorms during the summer. These MCSs develop along the persistent mei-yu front, and often exhibit quickly developing parallel back-building, or training thunderstorms, resulting in torrential flooding. A research team led by Dr. Zhemin Tan, Professor at the School of Atmospheric Sciences of Nanjing University, analyzed the influences of the regional landscape that lead to consistent MCS back-building in the Yangtze river basin.
