From the material to analyze how the tent can prevent lightning strikes during lightning weather

1. As an excellent conductor, is an aluminum rod more attractive to lightning than a glass rod?

The choice of lightning is first of all according to the height of the conductor, among several conductors, it hits the highest.

In addition, because lightning is usually rainy, no matter the glass pole or aluminum pole, the fabric of the tent becomes a conductor due to wet water.

Therefore, in attracting thunder and lightning, more is determined by the height rather than the material of the pole.

2. How to prevent the tent from being struck by lightning?

Lightning damage mainly comes from two aspects: 1 is a direct hit, 2 is a high voltage arc.

To avoid direct splitting, the simple principle is not to be the high point of this area, and the standing birds are the easiest to split.

The arc is an air discharge phenomenon caused by the high voltage of lightning. After hitting an object, the instantaneous high voltage will form an arc near the object, causing injury.

Therefore, while not becoming a high point, it is also necessary to avoid camping next to the high point, otherwise it will still be hit by the arc.

Therefore, the ideal way is to choose a place where the overall terrain and vegetation height is relatively low, and can keep a certain distance from tall plants or buildings.

3. If it is hit, which of aluminum rod and glass rod is better?

Theoretically, the glass rod can not share the current through the body because it is not conductive, and the aluminum rod can be used as a parallel conductor to help the body withstand part of the current.

There have been cases in history where people struck by lightning were spared because their clothes were soaked and became conductive.

Therefore, the wetter the tent, the more conductive the poles are, and the less damage they cause after being hit.

However, this cannot avoid the huge damage caused by the high-voltage arc, so once it is hit, it is extremely dangerous.

In terms of lightning strikes, it can be divided into two situations:

1 is the glass rod or aluminum rod which is more lightning-inducing. If you ignore the actual use, the aluminum rod is indeed more lightning. But in fact, because the tent has become a conductor on rainy days, and the poles are usually not exposed outside the tent, this difference is not significant. Of course, a thunderbolt on a sunny day or a large number of external tents with metal poles are not considered.

2 is whether the glass rod or aluminum rod is more likely to avoid harm if it is hit.

This question can be seen like this:

A We are talking about the lightning hitting the tent instead of directly hitting the human body. There is no direct contact between the aluminum rod and the human body. So this situation is completely different from the fishing rod hitting the wire to kill the person.

B Lightning strikes the tent not to directly hit the human body. At this time, it is not the current that directly passes through the human body but the arc and high temperature to avoid. Therefore, the effect similar to the rubber shoe principle is uncomfortable in this case.

C. The huge energy of lightning must be converted. Grounding through conductors, arc generation, and high temperature are all possible in this process.

In any case, choosing the right camp to avoid lightning strikes is the right way. The aluminum pole tent is a theoretically safer option.

When the lightning is very strong and there is no suitable terrain, you can even pull the trekking pole or tent pole to the longest, insert it on the ground about 10 meters away from the tent, and curl up in a tent without a pole.

So the conclusions are as follows:

1. If it is raining and thunders, the aluminum pole is not more dangerous than the glass pole, it may also be safer. Because no matter what kind of pole tent becomes a conductor at this time, the focus is on who can better digest the current after a lightning strike.

2. Aluminum rods are more dangerous if it is thundering on sunny days. Because at this time only aluminum pole tents attract lightning strikes.

3. The selection of poles is only a secondary lightning protection measure. What really matters is to grasp the basic principles of camp selection and prevent lightning measures.
