How are thundershowers generated, and do thundershowers have to be showers?

Thundershower refers to a weather phenomenon in which thunder is accompanied by showers. When thundershowers come, there are often strong winds and thunderstorms. Persistent and intense thunderstorms, often reaching the level of heavy rain.

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 moisture, 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.

Thundershowers can be bursting or lasting longer.

A thundershower is a rain shower accompanied by thunder and lightning.

Typically, thundershowers are more intense than showers and are accompanied by thunder and lightning. Thundershowers are common in summer.

Showers also occur in other seasons.

Not necessarily, sometimes thundershowers keep falling and go on all day.

If it's not a shower, why do you call it a thunder shower?

Isn't it over if you just call it a thunderstorm?

Thundershowers are specifically defined as showers with additional lightning phenomena.

A thundershower is a rain shower 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.

Not necessarily him, but there must be thunder.

Causes: The formation of thunderstorms must meet certain conditions, that is, there must be sufficient water vapor leakage in the air, there must be the power to make the moist air rise, and the air must be able to produce violent convective movements. In spring and summer, due to the influence of the warm and humid airflow from the south, the air is humid, and at the same time, the solar radiation is strong, the air near the ground is constantly heated and rises, and the cold air in the upper layer sinks, which is easy to form strong convection, so there are many thunderstorms and even hail.

In winter, due to the control of the continental cold air mass, the air is cold and dry, and the solar radiation is weak, the air is not easy to form violent convection, so thundershowers rarely occur.

1. In summer, because the evaporation rate of water vapor from the sun directly hitting the ground is higher than that of other seasons, the air temperature close to the ground is relatively high, so there will be more water vapor, and the smaller the air density, the air will become lighter, and the lighter air will keep rising, with the increase of altitude, the temperature will gradually decrease, and the air will gradually become cooler and unable to accommodate abundant water vapor, and a part of the water vapor will form small water droplets, and clouds will appear in the sky.

2. Because the water droplets are too small, the hot air flow of the riser tube also drags them and pushes the suspended water droplets higher, and the clouds will accumulate more and more. When the small water droplets in the cumulonimbus cloud collide to form larger water droplets and begin to fall, the hot air rises from the ground and rushes into a strong net, and the friction between the two brings an electric charge, and the updraft carries a positive charge and the falling water droplets have a negative charge.

3. Over time, a large number of positive charges have been developed at the top of the Cumulonimbus cloud and a large number of negative charges at the bottom. When the water droplets in the cloud become larger and larger, the updraft heat cannot hold up, and when it falls from the cloud, the heat in the lower layer will become cold when it is rained, and it will fall directly from the ground, at which time the charge begins to discharge, accompanied by a rumbling thunder.

Because lightning is faster than thunder, people see lightning before they hear thunder, and sometimes thunder is caused by clouds and mountain peaks reflecting thunder on the ground.

Thundershowers are a short-lived but intense precipitation phenomenon that usually occurs during the summer or hot season.

Three basic conditions are required for thundershowers to form: adequate water vapor, an unstable atmosphere, and updrafts.

When solar radiation enters the Earth's atmosphere, the temperature of the ground and water surface increases. This causes the surrounding air to be heated and expanded, becoming lighter, creating an updraft.

Updrafts encounter a colder, more stable atmosphere during their ascent, causing water vapor to condense into clouds, forming cumulus clouds. If the cumulus cloud continues to grow and rise to higher heights, thunderstorm clouds are formed.

Inside a thunderstorm cloud, water droplets and ice particles in the cumulus cloud collide to form an electric charge. These charges accumulate inside the cloud until they accumulate to a certain level, at which point they are discharged, forming lightning. Lightning generates high temperatures and pressures, causing the surrounding air to rapidly expand and **, forming sound waves, which are the thunder we hear.

When lightning occurs, it also heats the clouds and creates a strong updraft, further strengthening the convection inside the clouds and creating stronger precipitation, which is what we see as thundershowers.

In conclusion, thundershowers are formed by a combination of factors such as abundant water and steam, an unstable atmosphere, and updrafts.
