Which is prone to lightning in hot and humid areas or hot and dry areas

Hot and humid areas. Thunder activity weakened with the increase of geographical dimension, and there were more lightning activities in hot and humid areas than in cold and dry areas. Geographically, there are more in the South than in the North.

Thunder activity decreases with the increase of geographic latitude, and there is more lightning activity in hot and humid areas than in dry and cold areas. Geographically, there are more lightning activity in the south than in the north, inland more than coastal, more mountainous than plain, and all other things being equal, lightning activity is weaker in areas with poor soil conductivity. In mountainous areas, there are more thunderstorms on the southern slope of the mountain than on the northern slope, more on the seaside than on the seaside slope, more landslides on the flat ground in the mountains than in the canyon, and at the same time, the storm corridor is also prone to thunderstorms in places where the wind direction is the same, or where the wind is downwind.

Areas with metal deposits buried underground are also prone to landmines. Isolated towering features, such as power poles, railways, overhead power lines, lightning rods, lightning cables, lightning belts, etc., are the best passages for thundercloud discharge.

Of course, thunder and lightning are more likely to occur in hot and humid areas, so let's start a small science popularization.

The thunder and lightning capital is actually in the lake (attached: the world's high-incidence areas of thunder and lightning).

Although South America lags behind Africa in terms of quantity, Lake Maracaibo in Venezuela deserves to be the "global lightning capital". A study by American scientists has found that Lake Maracaibo has an average of 297 days of lightning in a year.

In a 2015 report released by NASA, the world's top 10 lightning destinations were published, and Lake Maracaibo in Venezuela ranked first with lightning density per square kilometer per year, followed by the Congo with an average annual lightning density of and .

From the perspective of regional distribution, most of the top ten lightning high-incidence areas are located near the equator, except for Pakistan, the others are occupied by African and South American countries.

The world's most lightning occurrence.

Although China is not in the world's high-incidence area of lightning, the number of lightning occurrences is not uncommon, especially from June to August.

According to the relevant reports of China Weather Network and China Meteorological News, China's high-incidence areas are mainly concentrated in Yunnan, Guangxi, Guangdong, Hainan and the Qinghai-Tibet Plateau, with an average annual thunderstorm days of more than 70 days. In June-August, these areas experience lightning on average more than a third of the time per month. Haikou, Guangzhou and Lhasa are the three provincial capitals with the most frequent lightning frequencies in China.

In contrast, lightning is scarce in northwest China, such as Xinjiang and Inner Mongolia, with an average annual thunderstorm of less than 20 days.

Thunder and lightning are more likely to occur in hot and humid areas, because in order to produce thunder, it is necessary to accumulate enough charge in the sky, and in hot and dry areas, the moisture in the air is scarce, and it is difficult to form enough clouds, and it is difficult to generate lightning without clouds carrying charges.

Hot and humid areas, of course.

Because the damp heat is easy to form clouds.

Only when there are clouds can there be thunder and lightning.

A hot thunderstorm is convective rain, which is formed by the evaporation of the ground by heat, and is called a hot thunderstorm when there is thunder and lightning.

The place with the highest number of thunderstorm days is Mengla, Xishuangbanna, with an average of more than 120 thunderstorms per year.

Extended Information: Precautions for Driving in Thunderstorms!

Although cars are not afraid of lightning strikes, what else do you need to pay attention to when driving in thunderstorms?

1. Try not to drive in thunderstorms, and it is safest indoors.

Minimize going out during thunderstorms, and it is safest indoors. Of course, if you can't avoid driving, it's safer to stay in the cabin than outside.

2. Do not get out of the car rashly to check the condition of the car after being struck by lightning.

The car is the best protective shell in the event of thunder, and it is the safest for people to hide in the car. If you are struck by lightning in the middle of driving, you should never get out of the car to check the condition of the vehicle, because the outside of the car is much more dangerous than the inside. The best way to deal with this is to find a safe place to park and wait until the thunderstorm has completely passed before getting out of the car to check.

3. Reduce the speed of the vehicle as much as possible on the highway and in the open area.

In terms of lightning strike probability, a moving vehicle is more likely to be struck by lightning than a stationary vehicle. Because during the driving process, the air movement will cause local electric field changes, that is, the faster the speed, the greater the change. This explains that most of the vehicles in the news that have been struck by lightning have occurred on highways.

4. Don't hide under big trees or large billboards during thunderstorms.

During a thunderstorm, a tree or a large billboard can collapse at any time, so we park next to these objects and may have to say goodbye to your car at any time.

5. Try not to hit ** and listen to the radio in the car when thundering.

In case of lightning weather, you should try not to use your mobile phone, and it is recommended that the owner put away the antenna outside the car and temporarily turn off the car stereo in the event of lightning to avoid the current being introduced into the car after the car is struck by lightning, causing electrical circuit failure.

Of course, it is warm areas that are more prone to thunder and lightning.

This is because there is plenty of moisture in warm areas.

A lot of moisture is more likely to form a cumulonimbus cloud.

Thunder and lightning are more likely to occur when there are many cumulonimbus clouds.
