Abstract：
The precipitation during the Meiyu season (from June to July) has significant implications for droughts, floods, water resource management, and decision-making in the middle and lower reaches of the Yangtze River. Investigating the sources of Meiyu rainfall can help regulate and manage the Meiyu precipitation from its origins. The author used an atmospheric precipitation water vapor tracing numerical model to trace the precipitation in the middle and lower reaches of the Yangtze River (26.5°N-33.5°N, 104.5°E-122.5°E) during the Meiyu season from 1991 to 2020. Then obtained a 30-year distribution of water vapor sources for Meiyu rainfall in the Yangtze River Basin. The model’s driving data were based on observed measurements, and multiple experiments were conducted for comparison and validation, ensuring the reliability of the simulation results. The dataset includes: (1) boundary of the study area; (2) yearly precipitation moisture source during the Meiyu period, with spatial resolution of 1°x1°, and the unit is mm; (3) yearly surface precipitation during the Meiyu period. The dataset is archived in .nc, .shp and .xlsx data formats, and consists of 9 data files with data size of 13.1 MB (Compressed into one file with 10.7 MB). The research results based on this dataset have been published in Weather and Climate Extremes, Vol. 43, 2024.
