What does rainy weather mean?

Meiyu weather is a warm and humid air flow in the Pacific Ocean brought by the southeast monsoon in June and July every year, which passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, south-central Japan and south Korea, and is a climate phenomenon of continuous rainy days. Because it is now the mature period of plums in the south of the Yangtze River, it is called "Meiyu".

Meiyu is a unique weather and climate phenomenon in the middle and lower reaches of the Yangtze River in early summer. It is the result of the stagnation of the Yangtze River basin during the northward movement of the main rain belt in eastern China. Meiyu is over and midsummer is coming. The change of this season every year is roughly the same as the movement of the rain belt with the season, forming a certain climate regularity. However, the annual plum rains are not completely consistent, and there are great interannual changes.
