Why does it rain so much, why does it rain so much?

When there is a lot of moisture in the air, it rains a lot.

Why does it rain?

Rain is a drop of water that falls from a cloud, the water on the surface of the land and the sea evaporates into water vapor, and the water vapor rises to a certain height and becomes a small droplet when it is cold, and these small droplets form a cloud, which collides with each other in the cloud and merges into a large droplet, and when it is too big for the air to support, it falls from the cloud and forms rain. Rain can occur in a variety of ways, from drizzle to continuous rain and downpour showers. Rain is the most important source of fresh water in human life, and plants must also be nourished by rain and dew to thrive.

But flooding caused by heavy rains can also bring great disasters to human beings.

When water on Earth is irradiated by sunlight, it becomes water vapor and evaporates into the air. When water vapour meets cold air at high altitude, it condenses into small water droplets. These small droplets are small, with a diameter of only millimeters and a maximum of millimeters.

They are small and light, held in the air by updrafts in the air. It was these small droplets of water that gathered together in the air to form clouds. For these small droplets to fall to the ground as raindrops, they would have to increase in size by more than 1 million times.

How do these small droplets grow their size to more than 1 million times? It mainly relies on two means, one of which is condensation and condensation increase. The second is to rely on the collision and growth of cloud droplets.

In the early stages of raindrop formation, cloud droplets mainly rely on the continuous absorption of water vapor around the cloud body to condense and condense themselves. If the water and gas energy sources in the cloud are constantly replenished and the surface of the cloud droplets is often supersaturated, then this condensation process will continue, causing the cloud droplets to grow and become raindrops. However, sometimes the amount of water vapor in the cloud is limited, and in the same cloud, the water vapor is often in short supply, so that it is impossible to make each cloud drop increase into a larger raindrop, and some smaller cloud droplets have to be merged into the larger cloud droplets.

If water droplets and ice crystals coexist in the cloud, the process of condensation and bloom increase will be greatly accelerated. When the droplets in the cloud increase to a certain extent, due to the increasing size and weight of the large droplets, they will not only catch up with the slower small droplets in the process of descending, but will also "swallow" more small droplets and make themselves stronger. When the large cloud droplets grow larger and larger, and finally the air can no longer support them, they fall straight from the clouds to the ground, becoming our common rain.

This year's Renchen year is a year of water prosperity, and there is naturally a lot of rain.

There was too much water in the sky.

Summary. Hello, it's not the same. First, the amount of precipitation is different.

Heavy rain: Heavy rain with 24-hour precipitation of 50 mm or more.

Heavy rain: Heavy rain has a 24-hour precipitation of millimeters.

Second, the hourly precipitation is different.

Heavy rain: Heavy rain has more than 16 mm of precipitation per hour.

Heavy rain: Heavy rain has an hourly precipitation of millimeters.

Third, the early warning signals are different.

Heavy rain: Rainstorm warning signals include blue, yellow, orange and red.

Heavy rain: There are no special warning signs for heavy rain.

Is heavy rain the same as heavy rain.

Hello, it's not the same. 1. Precipitation varies Heavy rain: The 24-hour precipitation of a heavy rain is 50 mm or more.

Heavy rain: The 24-hour precipitation of large branches is millimeters. Second, the hourly precipitation is different, and the rainstorm is fiercely destroyed:

Heavy rains have more than 16 mm of precipitation per hour. Heavy rain: Heavy rain has an hourly precipitation of millimeters.

Third, the warning signals are different Heavy rain: The warning signals for heavy rain include blue, yellow, orange, and red. Heavy rain:

There are no special warning signs for heavy rain.

Fourth, the hazards are different Sun raid heavy rain: heavy rain is easy to produce geological disasters such as flash floods and debris flows Heavy rain: the rainfall of the big brother rain is easy to produce water accumulation. Noisy.

The similarity is that both heavy rain and torrential rain are pouring rain.

Yes. Moderate to heavy rain is the same as heavy rain.

Moderate to heavy rain means that the size of the rain is between moderate and heavy rain; And moderate rain turns to heavy rain, as the name suggests, rain gradually changes from medium rain to heavy rain.

Of course, this is all a special term for weather forecasting, and the actual situation is not very different.

Is the rain heavy in the middle of the rain?

Moderate rain: refers to the amount of rain falling in millimeters in a 24-hour period.

Is it heavy rain in moderate to heavy rain?

Moderate to heavy rain: refers to rainfall in millimeters in a 24-hour period.

Okay, beauties.

Heavy rainstorms are caused by an abundant and continuous stream of water vapor, strong and persistent updrafts, and instability of the atmospheric structure. Large, medium and small weather systems at various scales and a favorable combination of underlying surfaces, especially topography, can produce large rainstorms.

The weather systems that cause widespread heavy rainfall in China mainly include fronts, cyclones, shear lines, low vortices, troughs, typhoons, easterly waves, and intertropical convergence zones. Heavy rainfall refers to the rainfall of 100mm or more and less than 250mm (100-250mm) in 24 hours, which is the regulation of China's meteorological work. Due to the vast territory of China, the intensity of precipitation varies greatly from place to place, so the rainfall standards are somewhat different.

The weather patterns of heavy rainfall in China can be divided into four categories: stable meridional type, stable zonal type, middle and low latitude interaction type, and heavy rain transition type.

As rivers, rivers, lakes, and seas are irradiated by the sun, the water inside them becomes water vapor. The water vapor rises and turns into small droplets, and finally into clouds. The small water droplets and Xiaoice crystals that make up the cloud are supported by the upward airflow, but the rising airflow is still transporting water vapor in.

The small water droplets in the cloud and the Xiaoice Tongjing collide with each other in motion, thus increasing in size. Then, as the volume of the ice crystals in the upper layer of the cloud slowly increases, the water droplets fall between the droplets in the lower part of the cloud, and the water droplets become larger and larger. When these droplets are so big that the updrafts can't hold them, it rains down.

The more you have, the more likely it is to rain.

Why does it rain? That's because of the change in the weather, the change in the climate, so in other words, there is rain in different areas, maybe snow.

More rain will affect the growth of plants, can inhibit the respiration of plants, and even die.

During the rainy season in the middle and lower reaches of the Yangtze River in China, there will be a long period of gloomy and rainy weather, when all things are very prone to dampness and mildew.

When thundershowers come, there are often strong winds and thunderstorms. When the wind comes, the sand and rocks are scattered, and the roof is blown down and the wall is blown down. In the wind and rain, things in the street dance in the wind, fly everywhere, and even uproot big trees.

Constant rainy days can also affect people's mood, making them feel bored and depressed.

Causes of heavy rainfall: a steady stream of water vapor, strong and persistent updrafts, and unstable atmospheric structure. The water vapor in the atmosphere is transported upward with the rising air current, and the water droplets in the cloud continue to increase under its influence until the updraft can no longer support it, and it falls sharply to the ground pure grinding surface, forming a torrential rain.

According to the regulations of the Meteorological Bureau, heavy rainfall with a precipitation of more than 50 mm in 24 hours is called "heavy rain".

The thunder sounded, and the rain continued to fall like beads with broken threads. The rain poured incessantly, and the rainwater that flowed down from the eaves of the houses pooled into small streams in the streets. Heavy rain fell frantically from the sky, and the dark sky seemed to be about to collapse.

The wind chases the rain, the rain chases the wind, and the slow wind and the rain unite to chase the dark clouds in the sky, and the whole world is in the rain. The rain is like thousands of silver threads falling from heaven. Dark clouds rolled in the sky, and in an instant, it poured down from the sky.

Helium auxiliary trance berry drink in the bucket to caress the laa In an instant, the raindrops formed a line, and with a "boom", the heavy rain poured down from the mountain sky as if the sky had fallen. The wind swept the torrential rain like countless whips, and whipped it fiercely against the glass window. The autumn rain was like smoke and mist, silently falling on the rubble heaps of the clearing, on the dead branches and leaves, drenching the ground, drenching the houses, and drenching the trees.
