It s still raining when the thunder stops, why, why does it rain when the thunder strikes

A thundershower is a rain shower phenomenon accompanied by thunder and lightning. Occurs under thunderstorm cumulonimbus clouds. It is characterized by large-scale cloud movements, much more violent than showers, accompanied by electrical discharges, and is common in summer.

In summer, direct sunlight causes water on the ground to evaporate faster than in winter, spring, and autumn. The air close to the ground is warmer and can absorb more water vapor, which causes the density of the air to decrease, and the air becomes lighter, and the lighter air keeps rising. As the altitude increases, the temperature gradually drops (every 100 meters of ascent, the temperature decreases by a degree) and the air cools down.

When the air is cold, it will not be able to contain the abundant water vapor, and some of the water vapor will condense into small water droplets, and the sky will become cloudy. This is the Cumulonimbus cloud.

When the small water droplets in the cumulonimbus cloud collide and merge into larger droplets, they begin to fall, while the hot air rising from the ground rushes upwards vigorously, and the friction between the two takes on an electric charge. The rising air flow is positively charged, and the falling water droplets are negatively charged. Over time, a large number of positive charges accumulate at the top of the cumulonimbus cloud and many negative charges at the bottom; The ground is also positively charged by the negative charge at the base of the cumulonimbus cloud.

The water droplets in the cloud merge and increase until the updraft can no longer hold up the hot air current, and it falls straight down from the cloud. The thermal currents below rained down, and suddenly cooled, no longer rushing upwards, but swooping down on the ground. At this time, the charge in the air began to discharge, accompanied by a rumbling thunder.

Because lightning travels at the speed of light (300,000 km/s) and thunder travels at the speed of sound (331 m/s), people see lightning before they hear it. Sometimes the thunder drags on for a long time, which is caused by clouds, mountain peaks and the ground reflecting the thunder back and forth.

It is not certain that there will be thunder first and then rain, it will rain if there is no thunder first, and it will rain first and then rain, it is just the same kind of situation.

There is a natural phenomenon of rain first, and then thunder, in the summer encountered, the beginning of the dark clouds quickly pressed over, there was no thunder, it rained heavily, non-stop, but after a long time, there was thunder, sometimes the rain is almost over, there is thunder, after the rain soon stopped, the clouds moved elsewhere, such a situation often appears in the local formation of thunderstorms.

Some thunderstorms often last for a while, and then there is thunder.

Sometimes light rain turns to thundershowers, that is, it starts to rain lightly, and after a while, thunder appears, and sometimes the rain will increase.

In summer, the weather is very prone to rain, sometimes only one or two hours of heavy rain in the afternoon, and there will be strong winds and thunderstorms, so it often feels hot or humid in summer. But sometimes it rains without thunder, so what's going on in this situation?

Because there are certain conditions required for thunder when it rains. When it rains, some of the clouds in the sky are positive and some are negative. When two clouds collide, lightning is emitted and a large amount of heat is released at the same time, causing the surrounding air to heat up and expand.

Instantaneously heating the expanded air will push the surrounding air, producing a strong ** vibration and forming a thunderous sound.

Lightning is the phenomenon of electrical discharge in thunderstorm clouds. The formation of thunderclouds generally requires two conditions: sufficient water vapor and vigorous convective movement. In winter, due to the cold and dry air, the solar radiation is weak, and it is not easy to form convection in the air, and there is less thunder and lightning.

However, sometimes in winter, when the temperature is too high, thunderclouds can form, thunder and lightning appear, and rain and snow appear.

If you are indoors, you will not be struck by lightning, but if you are outdoors, you should be careful, and do not hide under trees, which is very dangerous. Lightning usually strikes the tallest and sharpest places, and as a result, isolated tall trees or buildings are often the most susceptible to lightning strikes. If you are indoors, you don't have to worry too much about lightning rods in general city buildings, try not to use TVs, computers, and don't stand by the window.

If there is thunder on the road, you must stay away from the open place as soon as possible and walk into the room as soon as possible to escape. If there are no buildings nearby, hide in your car and close doors and windows. If you are in the mountains, run to the lowlands as soon as possible and do not go near places with water such as rivers and streams.

Do not go near large trees, tall antennas, power poles, metal railings, as lightning is likely to hit these protruding objects and then injure you through ground currents or indirectly.

The movement of air currents in the air at high altitudes drives the movement of cumulus clouds in the upper altitude, and the friction between the clouds causes the clouds to carry different kinds of electric charges. Since the same kind of charges repel each other, positive and negative charges are concentrated at both ends of the cloud. The faster the air moves and the thicker the clouds, the more electricity it carries.

When the amount of electricity carried by the cumulus cloud reaches a certain level, it is discharged through the air, neutralizing the two charges. When an electric current is passed through the air, it heats up, causing the air to expand rapidly and make a loud noise. This is a traffic mine.

If the charged cumulus cloud is close to the ground, the ground should carry a charge different from the underlayer due to static electricity. When the charged amount reaches a certain level, the cumulus cloud will discharge to the ground, which is the ground lightning that can easily cause disasters.

Let's talk about it briefly:

Let's start with the rain. The water vapor in the air is condensed into small water spots or Xiaoice crystals at high altitude, and the small water spots or Xiaoice crystals collide and merge with each other, becoming larger and larger, and when the air cannot support it, it will fall, and when the low-altitude temperature is higher than O, it is rain.

To simulate this process, it is first necessary to have a large amount of water vapor in the air, which can be done by heating the water; secondly, to try to condense the water vapor, collect it, and land, which can be done by using ice; In order to prevent the water vapor from flying around, you can use a small dish to cover the rim of the cup containing the water.

Thunder is a large-scale discharge phenomenon produced by clouds with different charges in the sky, when they are close to each other, sparks and sounds will occur when discharged, the sparks are lightning, and the sound produced is thunder.

As for the wind, it is simply said that the wind is formed by the flow of air, and any place on the earth is absorbing the heat of the sun, but due to the unevenness of heating in each part of the ground, the degree of cold and warm air is not the same, so the warm air expands and rises after becoming lighter; The cold air cools and becomes heavier and then falls, so that the cold and warm air flows and forms the wind. In meteorology, wind often refers to the horizontal movement of air and is expressed in terms of wind direction, wind speed (or wind force). Wind direction refers to the direction of the wind, which is generally expressed in 16 directions or 360 degrees.

When expressed in 360 degrees, it is measured clockwise from north.

Why does it rain and thunder rain when it rains.

Thunder and rain have no mother-child relationship!

So if it thunders, it rains.

It's a coincidence!

Not necessarily! Sometimes it doesn't rain when it's just thunder.
