Plain Language Summary: Southwesterly flows formed in Mei-yu season due to a deepening mid-latitude trough over eastern China and the southwestward extending Pacific high. The southwesterly flow axis was located roughly over Taiwan, and it shifted southeastward as the Pacific high weakened. At the same time, the high moisture zone covered the northern South China Sea and the entire island of Taiwan. As a result, moisture-laden air was transported to the Taiwan area by the strong southwesterly flow, providing favorable conditions for continuous rain in Taiwan.
