When does the dragon boat water usually arrive in 2022?

Dragon Boat Festival is a traditional festival with a long history. During the Dragon Boat Festival, eating zongzi and dragon boat racing are two main customs. Around the Dragon Boat Festival, there will be a period of concentrated precipitation, especially in South China, with heavy rainfall and strong rain. The precipitation in this period is also called Dragon Boat Water and Dragon Water. Let's get to know each other.

1, 202 1 When does dragon boat water usually appear around the Dragon Boat Festival, which is also the season with the largest rainfall in a year? The Dragon Boat Festival is on the fifth day of the fifth lunar month, and the solar calendar is usually from the end of May to June. Meteorology generally refers to the annual rainfall between May 2 1 and June 20 as dragon boat water.

It is called dragon boat water because there is a custom of dragon boat racing on the Dragon Boat Festival, which is a period of relatively concentrated precipitation. It usually lasts for several days, from heavy rain to heavy rain, so people call it Dragon Boat Water, also called Duanyang Water, Dragon Precipitation, Dragon Water and Dragon Boat Festival Water. People used to think that washing dragon boat water could ward off evil spirits.

2. When will the dragon boat water end? It usually ends in late June. If the precipitation is no longer concentrated, it can be regarded as the end of the dragon boat water. Meteorologically, it ends on June 20th every year. Dragon boat water is very common in South China. Every year in late May, with the arrival of the South China Sea summer monsoon, the water vapor situation in China has improved, and the precipitation in South China has increased significantly.

3. The reason for the formation of dragon boat water from late May to June coincides with the alternation of winter in the South China Sea and Xia Feng. The South China Sea summer monsoon usually breaks out in mid-May. After the monsoon broke out, it pushed to South China, resulting in monsoon convective precipitation. At the same time, the cold air in the north often goes south, and the intersection of cold and warm air leads to frontal precipitation. Under the combined influence of monsoon precipitation and frontal precipitation, large-scale concentrated precipitation often occurs at this time. During the Dragon Boat Festival, most parts of South China have entered the most abundant precipitation period in the last flood season. Not only does it rain heavily, but it also rains heavily.
