Why does rain fall all at once?

As the droplets collide, or more humidity condenses onto the surface of the droplets, they become too large to be supported by air currents, and fall as rain. For the rain to all fall at once, something would have to support it until all the water had merged into one mass. The wind doesn’t supply that much lift.

Do raindrops have to be small to fall?

We can call the growing droplet a raindrop as soon as it reaches the size of 0.5mm in diameter or bigger. If it gets any larger than 4 millimeters, however, it will usually split into two separate drops. The smaller drops are the ones that didn’t run into as many droplets.

When rain falls in very tiny drops what is it called?

It consists of drops of water falling from clouds; if the drops are very small, they are collectively termed drizzle.

What is a rain bomb?

Technically, there is no such thing as a ‘rain bomb’ in the field of meteorology. In recent years, individual thunderstorms that produce a narrow shaft of heavy precipitation have been described as being like a rain bomb. However, the technical term for this sudden deluge is a ‘wet microburst’.

Why does rain not hurt when falling?

The reason is called -Terminal velocity. This is a status of an object that stops to accelerate in free falling due to air friction and keeps its speed at the rate that other opposing forces allow.

Why rain drop falls slowly?

Answer: The reason is due to their speed falling through the atmosphere. Air flow on the bottom of the water drop is greater than the airflow at the top. Once the size of a raindrop gets too large, it will eventually break apart in the atmosphere back into smaller drops.

Why does the rain pour?

Water vapor turns into clouds when it cools and condenses—that is, turns back into liquid water or ice. In the cloud, with more water condensing onto other water droplets, the droplets grow. When they get too heavy to stay suspended in the cloud, even with updrafts within the cloud, they fall to Earth as rain.
