In recent days, China's precipitation has increased, especially in the south, where strong precipitation and strong convective weather are more obvious. A walk and go journey may not be so easy to shape. So, in case of a sudden bad weather during a field trip or camping, how to help yourself?
First of all, don't choose to go to the mountain area in case of bad weather! Especially when the meteorological department has issued relevant warning, even experienced outdoor donkeys should not take chances to camp in the mountain area. Because of the obvious microclimate in the mountain area, the transpiration of water conserved by forest vegetation in the daytime, and the strong air convection in summer, it is likely that a storm will come.
Lightning stroke
Thunderstorm is a common weather in mountain area in summer. It is often heard that tourists are injured or even killed by lightning in the wild. Although common sense tells you that you can't avoid under the trees or stay in the open place in thunderstorm weather. However, when you are in the wild, these common sense are difficult to fully apply.
The principle of lightning stroke is that the anode charge on the ground is attracted by the cathode charge at the lower end of the cloud layer, resulting in intense discharge. A great deal of charge needs to be released through a channel. Sometimes it's a building, sometimes it's a tower, sometimes it's a person in an open place. Therefore, to avoid lightning stroke is to prevent the human body from becoming the conductive 'channel' in the surrounding environment.
Therefore, when encountering thunderstorm in the wild mountain area, the following three points should be kept in mind:
1. When there is no place to avoid in the open space, try to find a low-lying place (such as the earth pit) to hide, or squat down immediately to reduce the height of the body;
2. Keep away from isolated and tall trees;
3. When multiple people coexist, do not lean on each other to reduce the target size and prevent lightning strike.
Mountain torrents, landslides and mudslides
Nowadays, the original forest is almost gone, the sand and gravel on the mountain can not be fixed by the roots of trees, so it is easy to loose and slide in case of heavy rain, causing geological disasters such as mountain flood, landslide, debris flow, etc.
When you are in a mountainous area in the wild, if there is sudden heavy rain, you should first determine which road section is prone to landslides?
The first is the place with steep slope and poor vegetation coverage, which is usually washed out by debris flow along some small hills and gullies; the second is the two sides of the road, which are prone to landslides due to the construction damage to the continuous surface structure and vegetation. Before the landslide, there are always some omens, such as small gravel constantly rolling down the hillside and so on.
In this dangerous area, we must pay more attention to observation, don't hesitate to find abnormal conditions, and we must pass quickly or wait for the opportunity in a safe place. For the hikers who often go camping, some mountains in Western Sichuan, Tibet and other places in China are prone to landslides and other disasters, because the geological structure is unstable, there are many mountains and valleys, the surface of the mountain is relatively loose, and once encountering bad weather, it is very dangerous.
In addition, special attention should be paid to the fact that the water level of mountain streams will skyrocket after heavy rain, so it is necessary to Avoid camping beside the streams in case of sudden flood at night.
Temperature loss
Temperature loss refers to the loss of heat more than heat supply, which causes the temperature of the core area of the human body to decrease, and produces a series of symptoms such as shivering, confusion, cardiopulmonary failure, and even death. In case of heavy rain or rainstorm in the wild mountain area, the body will take a lot of heat after being wet. In addition, the temperature in the mountain area is originally low, so we must pay attention to avoid human body temperature loss.
Rainproof equipment must be necessary. Lightweight hard shell clothes and trousers can be worn. Also bring a spare set of long sleeve quick drying clothes, quick drying pants and warm socks, which can play a maximum role when you are wet, and reduce the damage caused by the cold caused by the rain.
