I have only heard of dragon boat racing, but not dragon boat water. What is dragon boat water?
Dragon Boat Water, also known as Duanyang Water, Longtan Water, Dragon Boat Festival Water, etc., is a unique natural phenomenon in South China. It usually occurs around the Dragon Boat Festival. For the convenience of meteorological statistics, May is generally The precipitation from the 21st to June 20th is collectively called Dragon Boat Water. At this time, the warm and humid air flow in the south is active, and the cold air moving from the north meets in Guangdong, Guangxi, Fujian, and Hainan, often causing continuous and large-scale heavy precipitation. and heavy rain and windy weather. When the dragon boat water comes, the water level of the river rises rapidly, providing good site conditions for dragon boat racing, so it is commonly known as "dragon boat water" among the people.

But I still have a question, what is the cause of 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 the warm air flows continuously into the south of my country along the periphery of the subtropical high. At this time, there are often still heavy rains in the north. Cold air often moves southward, and when cold and warm air meet in South China, it is easy to form long-term heavy rainfall.

I never thought that there could be so much knowledge even when it rains. Will the dragon boat water bring any harm?
Dragon boat water generally has the characteristics of long duration, large rainfall accumulation and wide impact area. This year, the pre-flood season in South China is unusually early, and there has been significantly more rain since the start of the flood season. Special precautions need to be taken against natural disasters and production safety accidents such as urban waterlogging, small and medium-sized river floods, and geological disasters that may be caused by heavy rainfall!

Then I should pay attention to safety when I go out. If there is nothing wrong, I should not go to the beach or river to play, and I also want to remind Mom and Dad, please pay more attention when driving on hillsides. But what should I do if it rains suddenly when I go out? I must remember to bring an umbrella when I go out recently. If there is a heavy rain during outdoor activities, I should pay attention to the following points:
1. Find a suitable place to take shelter from the rain
Find a sturdy, higher-lying building to take shelter from the rain. Do not stay near rivers, watersides or under trees.
2. Do not rush forward through water, and be wary of puddles and manhole covers
Continuous rainfall can easily lead to accumulation of water on the road, sediment, garbage and other obstacles that can easily be washed underwater. But it is difficult for the human eye to identify; stay away from slippery floors such as marble, and drive slowly if you need to pass.
3. Pay attention to the surrounding wires.
Pay attention to the wires falling to the ground. If you find that high-voltage wires have collapsed, drooped or broken, stay away from danger and do not touch or approach them.
4. Stay away from unreliable walls
Avoid low-lying areas such as under bridges (especially recessed overpasses) and culverts; stay away from outdoor billboards, temporary walls at construction sites, and away from temporary walls at construction sites. Standing next to flimsy temporary structures.
5. Pay attention to roadside flood prevention safety warning signs
Do not get close to places with whirlpools to prevent falling into dangerous areas such as wells and pits with missing manhole covers.

Xiaowan, you are great! Thank you for teaching us so much today.
You’re welcome. I can recommend you a few picture books about rainstorm disaster prevention. You can read them at home. We can communicate and study together during school!
