Effect of water vapor transport and budget on precipitation in the Yangtze–Huang–Huai–Hai River Basin
Study region: The Yangtze−Huang−Huai−Hai River basin (3.19 million km2) in China, which is vital for China's economic development. Study focus: We employed the Eulerian method to identify the primary water vapor channels from 2005 to 2020, and the water vapor net budget over the basin was calcu...
