Doesn t there be thunder when a typhoon blows? Will there be thunder on typhoon days?

Due to the long history of our country, there are many legends circulating in history. Among the people, there are also many interesting experiences and sayings. There are many elderly people who often say that as long as they hear thunder, the typhoon will pass.

Although this is an empirical statement, it is also true. The reason why the typhoon basically passed when the thunder was heard was mainly because of three aspects. <>

The first aspect is that thunder has little to do with typhoons. Since thunder is a kind of static and stable weather, typhoons have nothing to do with static high electricity. Since there is no direct correlation between typhoons and thunder, if there is thunder, then it may also mean that the typhoon has passed.

The second aspect is that the statement is scientific. If the sky is tired, then it means that the typhoon is basically over. In terms of airflow, typhoon weather and thunderstorm weather.

It's completely different. Typhoons run in the horizontal direction, while thunderstorms run in the vertical direction. <>

Under normal circumstances, there is basically no lightning on typhoon days. If thunder is heard during a typhoon, it means that the air flow in the vertical direction is stronger than the air flow in the horizontal direction. This means that the typhoon has become very weak.

The third aspect is that thunder and typhoons have different causes. If the period is not summer and the convective process is not strong, then there will be basically no thunder. If you want to generate thunder, it is usually in the summer and the convection process is very strong.

Although typhoon weather may bring rain.

However, there will be no thunderstorms during typhoons. In general, if a typhoon makes landfall, there will be no thunderstorming. Probably because of these three reasons, this statement is true.

In addition to this saying, there are many other old sayings circulating among the people. Although there is some unsubstantiated basis, it is indeed in line with the facts. In the face of these rumors, netizens must remain sensible.

Can. If you look closely, although typhoons can also bring heavy rain, they basically do not produce thunderstorms, especially after the typhoon makes landfall, it is difficult to be accompanied by thunder.

Tropical cyclones such as typhoons are formed due to the evaporation and rise of seawater, which causes a low-pressure area to form in the middle, and finally the outer high-pressure atmosphere fills the low-pressure area, forming a cyclone with strong winds. The biggest difference between typhoon weather and thunderstorm weather is the direction of their air flow, typhoons operate horizontally, while thunderstorm weather is vertical, and only vertical conditions can produce convection under the action of gravity and collide to produce enough charge. As a result, it is very difficult to produce lightning on typhoon days, and the only thing that can accompany lightning is a particularly strong typhoon.

In its relatively central area, water droplets and ice crystals are chaotic, and it is possible for collisions to produce enough charge to trigger lightning, but it is very rare. .If thunder is heard on a typhoon day, it generally means that the strength of the vertical airflow exceeds that of the horizontal airflow, in other words, the typhoon has become weak.

Thunder can suppress typhoons, mainly because the sound propagates slowly in the medium, we sometimes hear thunder, the vertical airflow is already equivalent to the horizontal airflow, under this condition, the intensity of the typhoon will be reduced.

There is some truth to that. If we look closely, although typhoons can also bring heavy rainfall, they basically do not produce thunderstorms, especially after landfall, typhoons are unlikely to be accompanied by thunder.

It can't be suppressed, but most of the white clouds can be collected after thunder, and these white clouds will not form a typhoon.

Typhoon days are generally not thunderous.

The reason for the occurrence of thunder is that the air flow convection friction produces electric charge, which generally appears in the thunderstorm monomer or front, "thunder" means that there is strong convective weather, and thunderstorms have strong rising and falling areas, because the scale is small, so the interaction is very violent, resulting in thunder and lightning; Similarly, the front is where warm and cold air currents meet, where convection is intense and prone to lightning.

In contrast, a typhoon is a positive pressure warming system, in other words, a typhoon is an orderly single warm air mass: the bottom air flow converges into the center, spirals up at the eye of the wind, and flows out in the top secondary disperse. Therefore, it is not easy to produce violent friction caused by the different flow directions of the local airflow, so lightning generally does not occur.

Precautions on typhoon days:

1. Try not to go out by car.

During typhoon heavy rain and heavy rain, there are many waterlogged road sections, which is easy to cause congestion. It is recommended that car owners try not to drive out, especially novice drivers.

2. Park the vehicle in a safe location.

Regardless of whether you drive or not, the vehicle should be parked in a safe location. When choosing a parking space, you should carefully observe the surrounding conditions, drainage system, etc., pay attention to the flood prevention safety of parking lots and underground garages, and it is recommended to park your vehicles in higher ground and open places, and do not park under billboards, temporary buildings and trees with silver rocks, so as not to smash and flood vehicles.

3. Check the vehicle before driving.

When driving during a typhoon, be sure to check whether the vehicle lights, whole vehicle weatherstrips, brake devices, directions, circuits, tires, tire pressure, wipers and oil circuits are running well, so as to avoid danger caused by poor operation of parts while driving.
