What does dragon boat water mean? Meteorological causes of dragon boat water.

1 Dragon Boat Water, also known as Duanyang Water, Dragon Boat Festival Water and Dragon Precipitation, is a natural phenomenon around the Dragon Boat Festival in southern China. Before and after the Dragon Boat Festival, the warm and humid air flow in southern China was active. When it met with the cold air from north to south in Guangdong, Guangxi and Fujian in southern China, there would often be continuous and large-scale heavy precipitation. When Duanyang water comes, the water level of the river rises rapidly, which provides a good venue for dragon boat fishing. People call the heavy precipitation in this period "Dragon Boat Water".

2. Dragon boat water occurs from childhood to summer solstice. In the traditional culture of China, rain and dragons are linked. The dragon is not only an auspicious thing, but also the master of weathering rain. Dragonflies are flying in the sky and clouds are scattering rain. From the natural phenomenon, in midsummer, it is just the time when the black dragon flies south of the sky for seven nights. In the Book of Changes, Gangua says, "The flying dragon is in the sky." During the midsummer Dragon Boat Festival, the rainfall in South China often increases significantly.

3. "Dragon boat on water" is a phenomenon of heavy precipitation that affects South China and other places. Its causes are very complicated, mainly related to the "southwest monsoon". 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. After entering May every year, the force 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".
