| 英文摘要 | Survey data indicate substantial variations in precipitation in Beijing in recent years; however, a comprehensive investigation into the underlying causes remains lacking. Therefore, this study utilizes the Lagrangian water vapor tracking model to analyze the transport pathways of water vapor during the rainy season from 2020 to 2024. By quantifying the intensity of water vapor transport (QVT) and employing concentration-weighted trajectory (WCWT) analysis, the study further identifies potential source regions of water vapor. The results reveal that: (1) the water vapor responsible for July precipitation in Beijing primarily originates from Eurasian continental and oceanic pathways, including the Pacific Ocean and the South China Sea; (2) the westerly wind belt plays a dominant role in water vapor transport, while the southeast monsoon significantly enhances the contribution of oceanic water vapor; (3) reduced precipitation in low-value years (2020 and 2022) is linked to weakened water vapor transport from the ocean, attributed to a weakened southeast monsoon. This analysis confirms that the water vapor transport mechanism during the July rainy season is shaped by a combination of westerly transport and the monsoon system, with oceanic water vapor making a notably significant contribution to precipitation. |
