What causes rainwater? How Rainwater Forms Causes Rainwater Formation

Water, steam, clouds, rain, water.

The liquid is exposed to light, evaporates, and becomes water vapor.

When it rises, it reaches a certain height and becomes ice crystal particles or small water droplets due to the drop in temperature, which condenses into clouds. When the clouds evolve to a point where there is too much liquid in them to bear the weight, they will fall as rain.

1. Rain is a natural phenomenon.

is a drop of water that falls from a cloud. Water on the surface of land and sea evaporates into water vapor.

After the water vapor rises to a certain height, it is cooled and liquefied into small water droplets. These small droplets make up the cloud, and they collide with each other in the cloud and merge into large droplets. When it was too big for the air to hold, it fell from the clouds and formed rain, or water vapor.

2. The water on the ground absorbs heat and turns into water vapor, rising to the upper layer of the sky vapor layer, due to the low temperature of the upper layer of the vapor layer, the volume of water vapor decreases, the specific gravity increases, and the steam falls, due to the high temperature below the vapor layer, the heat absorption in the process of descending, rises again and meets the cold, and then falls, so that the gas molecules gradually shrink, and finally concentrate on the bottom layer of the vapor layer, form a low temperature zone at the bottom layer, and the water vapor is concentrated in the low temperature area, which forms a cloud. The clouds gradually become larger, the convection up and down inside the clouds becomes more and more intense, the temperature becomes lower and lower, and finally raindrops fall.

1. Rain is a natural phenomenon.

When the clouds reach a certain thickness, the water droplets that make up the clouds fall naturally to form rain.

2. Rain is the water on the earth that receives sunlight.

After irradiation, water vapor is formed, and the water vapor evaporates and rises into the air, where it encounters cold air and water vapor.

Condenses into water droplets.

Condensation releases heat and heats the temperature, so the warm air will continue to rise, and then when it is cold, the water vapor will continue to condense, and so on, and the updraft can stretch from low altitude to 10,000 meters altitude.

At higher altitudes, when the temperature drops below zero, ice crystals appear, and small water droplets and ice crystals form cumulonimbus clouds.

When the cumulonimbus cloud reaches the tropopause, the upward motion stops.

When the ice crystals in the cloud collide and merge with each other, some water vapor directly condenses and adheres to the surface of the ice crystals, the Xiaoice crystals will grow, and when the updraft cannot support it, it will fall under the action of gravity, and in the process of descending, the temperature at low altitude rises, and the ice crystals melt, which becomes rainfall.

Formation of rain: When the climate becomes cold, some of the water vapor in the air will liquefy into water droplets, and the water droplets will condense into rain again, which is known as rainfall. Rain comes from clouds, and there are two types of clouds, warm clouds and cold clouds.

Warm clouds are small water droplets formed by the liquefaction of water vapor. Cold clouds are Xiaoice crystals formed by the condensation of water vapor, and the ice crystals become larger and larger, melting into small water droplets as they fall.

in the form of rain. 1. Frontal rain (plum rain): The warm and humid airflow from the ocean meets the cold air from the land, because the cold air is heavy and the warm air is light, the warm and humid airflow is forced to rise early, and when it condenses, it forms a very long and wide rainfall belt, which is the frontal rain.

2. Convective rain: In summer, under the strong sunlight, the warm and humid air in the area of the local collision area rises sharply, and condenses to form rainfall, which is convective rain, which is called "thundershower" in meteorology, and we usually call it "bursting sky", in addition, typhoon rain is also a kind of convective rain.

3. Topographic rain: The warm and humid airflow from the sea and the ocean, when it encounters the mountains, is forced to rise, and when it encounters condensation, it forms rainfall. 4. Typhoon rain:

Hot and humid air over the tropical ocean swirls and rises strongly on a large scale. During the rise, the temperature drops rapidly, and a large amount of water vapor condenses into clouds and rain, which is called typhoon rain.

1. The reason for the formation of rain is because the water vapor in the air is condensed into water points or Xiaoice crystals at high altitude, and the small water points reed wheel or Xiaoice crystals collide with each other, merge and collide, merge and merge, becoming larger and larger, so large that the air will fall when it can't hold it, and when the low-altitude temperature is higher than O, it is rain.

2. In the early stage of raindrop formation, cloud droplets mainly rely on continuously absorbing 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.
