Why is it called dragon boat rain?

Xiaowan, why is it so hot during the Dragon Boat Festival holiday, and it began to rain again these two days?

Xiao Li, this is no ordinary rain. It has a domineering name, called "Dragon Boat Water".

I've only heard of dragon boat racing, not dragon boat water. What is dragon boat water?

Dragon Boat Water, also known as Duanyang Water, Longtan Water and Dragon Boat Festival Water, is a unique natural phenomenon in southern China, which generally appears around the Dragon Boat Festival. For the convenience of statistics, the precipitation from May 2/KLOC-0 to June 20 is generally called Dragon Boat Water. At this time, the warm and humid airflow in the south is active, and it will meet the cold air from north to south in Guangdong, Guangxi, Fujian, Hainan and other places, and there will often be a continuous strong range. When the dragon boat water comes, the water level of the river rises rapidly, which provides a good venue for dragon boat fishing, so it is commonly known as "dragon boat water" among the people.

But I still have a question. What is the reason for the formation of dragon boat water?

Generally speaking, from late May to mid-June every year, the South China Sea summer monsoon breaks out, and warm air flows into southern China along the periphery of the subtropical high. At this time, the cold air in the north often goes south, and the cold and warm air meet in South China, which is easy to form long-term heavy precipitation.

I didn't expect it to rain and have so much knowledge. What harm will dragon boat water bring?

Dragon boat water generally has the characteristics of long duration, large rainfall accumulation and wide influence area. The first flood season in South China is unusually early this year, and there has been a lot of rain since the flood season. Special precautions should be taken against natural disasters and production safety accidents such as urban waterlogging, floods in small and medium-sized rivers and geological disasters that may be caused by heavy rainfall!

Then I should pay attention to safety when I go out. I don't want to go to the seaside or the river for nothing, and I also want to remind my parents to pay more attention when driving through the hillside. But what if it suddenly rains when I go out? Remember to take an umbrella when you go out recently. If you suddenly encounter heavy rain in outdoor activities, you should pay attention to the following points:

1, find a suitable place to shelter from the rain.

Find a strong, high-lying building to shelter from the rain, and don't stay by the river, water or trees.

2, don't rush to wading forward, beware of puddles and manhole covers.

Continuous precipitation is easy to cause obstacles such as road water, sediment and garbage to be washed underwater, but it is difficult for human eyes to recognize; Stay away from the slippery ground such as marble. If you need to pass, you can walk slowly.

3. Pay attention to the surrounding wires

Pay attention to the grounding of wires. If the high-voltage line collapses, sags or breaks, please stay away from danger and do not touch or approach it.

4. Stay away from unstable fences

Avoid bridges (especially concave overpasses), culverts and other low-lying areas; Stay away from outdoor billboards and temporary fences on the construction site, and don't stand next to unstable temporary buildings.

5, pay attention to the roadside flood control safety warning signs.

Don't go near places with whirlpools to avoid falling into dangerous areas such as wells and pits with missing manhole covers.
