A cloud weighs hundreds of tons, why is it still suspended in the air? What is its composition principle?

The weight of a big cloud may exceed several tons, even thousands of tons, but such a heavy cloud can be kept high in the sky, of course, because there is one thing that can despise gravity, and that is the wind. The wind generated by the updraft holds up the clouds. The formation and result of clouds not only prove the failure of gravity, but also prove the law of force. Force has direction and magnitude. If you want to make a floating object, there must be a carrier in the existing technology of human beings.

The force opposite to gravity is equal, which is the effect of updraft on clouds. Strong convective weather often occurs in summer, forming a large area of rolling dark clouds. If you look carefully, you will find that the clouds are gathering and climbing up gradually to form rainfall better, because the altitude is high and the temperature is low. In strong convective weather, clouds can weigh thousands of tons. In extreme weather events such as typhoons, they can carry billions of water vapor. However, in the convective weather that only exists in the troposphere, the temperature in the troposphere increases with the elevation, and the heat from the ground in the upper stratosphere is very low.

For example, the movement of the atmosphere is mainly due to uneven heating directly caused by sunlight, and the wind formed by the atmosphere is parallel to the ground in a certain range, rather than rising air; The change of temperature with height is not obvious. The atmosphere on the earth is always in motion. Due to uneven ground heating, high-altitude heating is not very uniform. The hot air center becomes relatively thin, the atmosphere expands outward and rises to the sky, and the surrounding cold air flows to the low pressure center, thus forming an atmospheric circulation. Airflow can produce wind.

Clouds are formed because water vapor is blown high into the air by updraft. As the height rises, the water vapor in the atmosphere will condense and form water droplets or ice crystals. Water droplets and ice crystals formed in a certain range will refract and block light and form clouds. Clouds are not tightly combined, but a collection of small ice crystals and water droplets until the water droplets evaporate again or fall to the earth's surface with precipitation. The precipitation process is due to the continuous accumulation of small water droplets or ice crystals. The power of the earth always exceeds the lift of the upstream, forming rainwater to fall to the surface, but a few of them are blown away again by strong winds during the fall.
