en.wikipedia.org/wiki/East_Asian_rainy_season
The East Asian rainy season, commonly called the plum rain (Chinese and Japanese: 梅雨; pinyin: méiyǔ; rōmaji: tsuyu/baiu; Korean: 장마; romaja: jangma; Russian: затяжные, zatyazhnie), is caused by precipitation along a persistent stationary front known as the Mei-Yu front for nearly two months during the late spring and early summer between eastern Russia, China, Taiwan, Korea, and Japan. The wet season ends during the summer when the subtropical ridge becomes strong enough to push this front north of the region.
