What is the name of the rain on the Dragon Boat Festival?

1, Dragon Boat Water "It seems that it is the injustice of Qu Yuan and Chen that the Dragon Boat Festival is windy and rainy every year." It always seems to rain in Hunan around the Dragon Boat Festival every year. People often say that "the Dragon Boat Festival lifts all boats". Because there is a custom of dragon boat race on the Dragon Boat Festival, "Dragon Boat Festival Water" is also called "Dragon Boat Water".

2. The cause of Dragon Boat Festival water is closely related to the alternation of winter and summer monsoon in the South China Sea. The South China Sea summer monsoon usually breaks out in mid-May, which promotes and affects Hunan and produces monsoon convective precipitation. At the same time, the cold air in the north is reluctant to go to Hunan, and the convergence of cold and warm air causes frontal precipitation. Under the combined influence of monsoon precipitation and frontal precipitation, large-scale and concentrated precipitation often occurs in Hunan around the Dragon Boat Festival, that is, "Dragon Boat Festival Water".

3. Dragon boat race is a kind of heavy precipitation phenomenon that affects South China and other places, and its causes are very complicated. It is generally believed that the cause of "dragon boat water" is related to the alternation of winter and summer monsoon in the South China Sea. In terms of time, the weather in South China is the most complicated period around the Dragon Boat Festival. The South China Sea summer monsoon usually breaks out in mid-May, and the southwest warm and humid airflow pushes to South China, resulting in monsoon convective precipitation.

4. After entering May every year, the strength of warm and humid air flow from tropical ocean is constantly strengthened. South of Nanling, the temperature gradually rises and the weather turns hot, but the cold air does not retreat northward. The cold air in the north is reluctant to part with South China, and the convergence of cold and warm air causes frontal precipitation. Therefore, under the combined influence of monsoon precipitation and frontal precipitation, large-scale concentrated precipitation often occurs in Guangdong from late May to mid-June, that is, "Dragon Boat Water".
