East Asian rainy season

The East Asian rainy season (Chinese and Japanese: 梅雨; pinyin: méiyǔ; rōmaji: tsuyu/baiu; Korean: 장마; romaja: jangma), also called the plum rain, is caused by precipitation along a persistent stationary front known as the Meiyu front for nearly two months during the late spring and early summer in East Asia between mainland 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. These weather systems can produce heavy rainfall and flooding.
