Preliminary results on the Mei-Yu Frontal Heavy Rainfall Tracking Observation Experiment and Related Studies

This article introduces the five-year research plan of the project and the preliminary progress made over the past two years: 1. Implemented tracking observation experiments on the Mei-Yu frontal extreme precipitation associated in the middle and lower reaches of the Yangtze River for the years 2023 and 2024; 2. Investigated the triggering and maintenance mechanisms of extreme precipitation related to multi-scale interactions and associated thermodynamic conditions; 3. Conducted studies on the microphysical structure and evolution simulation of extreme precipitation. To be specific, the mechanism of low-level jet formation is analyzed during the rainy season in the Yangtze River Basin in 2024.
