Brief introduction of how thunderstorms form.

Question 1: How do thunderstorms form? People usually refer to the clouds where lightning occurs as thunderstorm clouds. In fact, there are several kinds of clouds related to lightning, such as stratocumulus, nimbostratus, cumulus, cumulonimbus, and the most important one is cumulonimbus. Lei Yun mentioned in general professional books refers to cumulonimbus clouds.

The process of cloud formation is a process in which water vapor in the air reaches saturation or supersaturation through various reasons and condenses. Water vapor saturation in the air is a necessary condition for cloud formation. The main ways are as follows:

(1) The water vapor content is unchanged, and the air is cooled;

(2) keeping the temperature constant and increasing the water vapor content;

(3) Not only the water vapor content is increased, but also the temperature is reduced.

But for the formation of clouds, the cooling process is the most important process. In the process of cooling, the cooling effect brought by ascending movement is the most common.

Cumulonimbus cloud is a kind of cloud formed in the process of strong vertical convection. Because the ground absorbs much more solar radiation heat than the air layer, the ground temperature rises more during the day, especially in summer. Therefore, due to heat conduction and heat radiation, the atmospheric temperature near the ground rises, the gas temperature inevitably expands, the density decreases, and the pressure also decreases. According to the principle of mechanics, it will rise, and the density of the air layer above it is relatively high, and it will sink. In the rising process, the hot airflow expands and depressurizes, and at the same time, it exchanges heat with the high-altitude low-temperature air, so the water vapor in the rising air mass condenses, and water droplets appear, forming clouds. In the process of strong convection, the fog droplets in the cloud further cool down and become supercooled water droplets, ice crystals or snowflakes, and gradually increase with the height. At the freezing height (-10℃), due to the latent heat released by the freezing of supercooled water, the cloud top suddenly develops upward and spreads horizontally near the tropopause, forming a cloud anvil, which is a remarkable feature of cumulonimbus clouds.

In the process of cumulonimbus cloud formation, positive and negative charges are accumulated in different parts of the cloud under the simultaneous action of atmospheric electric field, temperature difference electrification effect and debris electrification effect. When the charge accumulates to a certain extent, it will discharge between clouds or between clouds and the ground, which is what people usually call lightning.

Lightning has brought great disasters to human society with its great destructive power, especially in recent years, lightning disasters have occurred frequently, and the harm to the national economy has become increasingly serious. It is necessary to strengthen the awareness of lightning protection, actively cooperate with meteorological departments, do a good job of prevention, and minimize the losses caused by lightning.

Question 2: How is thunderstorm weather formed? The friction between water vapor and other impurities in the air, such as cold, blocked descent, produces charge, and violent movement of the atmosphere produces lightning, which is a brief introduction of thunderstorm weather.

Question 3: Introduction of Thunderstorm Story 30 points Summary of Thunderstorm Story (Introduction): Sifeng is Zhou's maid and Zhou's half-brother, and they also fall in love with Sifeng. Zhou Pingben had an affair with (Zhou's mother). Since she secretly loved Sifeng, she turned a blind eye to her heartbreak. Fan Yi knew that Zhou Chong liked Sifeng, so she invited her mother Ma Lu to be a guest. But I met Master Zhou. Only then did I realize that 30 years ago, I worked in the Zhou family, and she was pregnant with the sea, but she was finally abandoned. Ma Lu went to sea and remarried with Gui Lu, giving birth to four phoenixes. Therefore, Ma Lu hated the master. I planned to take Sifeng away from Zhou's home, but because she was pregnant, she asked to take her away. Ma Lu wants to faint. Now, she only urges them to go quickly.

Question 4: How do thunderstorms form? It's very simple. That's how they are formed.

Question 5: How are thunderstorms formed? The friction between water vapor and other impurities in the air, such as cold and falling, produces charge, and the violent movement of the atmosphere produces lightning and rain, which is a brief introduction of thunderstorm weather.

Question 6: What is the cause of the thunderstorm? Basically, my fighter level is in the third generation. However, many fighters under research have reached the advanced level in the world, including J- 13 circulating on the Internet, which has the level of four or five generations in all aspects.

Question 7: Introduction to the story of Thunderstorm (Introduction): Sifeng is Zhou's maid, Zhou's half-brother, and she also falls in love with Sifeng. Zhou Pingben had an affair with (Zhou's mother). Since she secretly loved Sifeng, she turned a blind eye to her heartbreak. Fan Yi knew that Zhou Chong liked Sifeng, so she invited her mother Ma Lu to be a guest. However, I met Master Zhou. Fan Yi realized that Luma worked in Zhou Jia 30 years ago, and she was pregnant with Zhou Ping and the sea, but she was finally abandoned. Luma remarried with Gui Lu and gave birth to four phoenixes. Therefore, Luma hates Master. Luma planned to leave Zhou Jia with four phoenixes, but because she was pregnant, she asked Zhou Ping to take her away. Luma wanted to faint. Now, she has to urge them to go quickly.

Question 8: Introduction to the background of Thunderstorm This drama is based on Cao Yu's famous drama Thunderstorm. 19811February, the dramatist Cao Yu wrote "Glory for China Culture-Thoughts on Watching the Ballet Thunderstorm" for the performance of the play, 1982 wrote "Cao Yu talks about the ballet Thunderstorm" (/kloc-0 1983 won the annual creative performance award of Shanghai Municipal Bureau of Culture 1980- 1982.

Question 9: How are thunderstorms formed? When the water vapor and other impurities in the air get cold, the friction between them and the falling obstruction produces electric charge, and the violent movement of the atmosphere produces lightning and rain. This is a brief introduction of thunderstorm weather.
