Since the drops are quite numerous, It appears that it is much larger than the eye. may come. However, this is not the case.

Bride, Why does rain flow in drops? let’s see.

For water vapor to turn into precipitation, it needs a condensation nucleus.

Condensation core; by air moving due to pressure, changing temperature and density, of very small dust or pollen particles carried to high altitudes occurs.

The droplets in the cloud begin to fall when they reach a size and weight that can withstand the thermal force pulling them upward. Although all clouds contain some moisture, only some of the clouds produce rain What remains evaporates into the air.

A cloud contains many particles that absorb moisture, and as these particles absorb water, precipitation droplets often form.

These water droplets, i.e. rain, that come down from clouds usually have a diameter of 0.5 millimeters.

Furthermore, before a raindrop lands on the ground, it moves toward the surface hundreds of times as it moves through the air. can attract small aerosol particles. Coagulation is the process by which droplets and aerosols attract each other, causing the droplets to become larger.

But no matter what, raindrops It remains at a diameter of 0.5 mm. Because the frictional resistance caused by air is greater than the surface tension that holds the drops together. For this reason, even if droplets larger than 0.5 millimeters are formed, they cannot stay together for a long time.

Larger droplets, even though they are unlikely to stay together, As it falls, it breaks up into smaller droplets and all types maintain a diameter of approximately 0.5 mm.

Additionally, the air surrounding a droplet slows it down as it starts moving faster.

In this case, even the smallest raindrop may not fall to the ground, as the rising airflow holds it in place It pushes up until it is big enough to fall down.

Here too, some raindrops can sometimes touch each other. When this collision occurs, some stick together to form a large droplet, while others break up into smaller droplets. As the number of drops increases, The amount of rain is also increasing.

However, the collision of droplets does not guarantee their coalescence. For this reason, the droplets do not form as a large puddle, as in a waterfall. They fall one by one, separated from each other.
