Why Does Rain Fall in Drops?

Because the drops are quite numerous, It looks like it’s much bigger than the eye. may come. However, this is not the case.

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

In order for water vapor to turn into precipitation, it needs a condensation nucleus.

Condensation core; by air moving as a result of pressure, changing temperature and density, from 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 resist the thermal force pulling them upward. Although all clouds contain some moisture, rain only falls from some of the clouds and What remains evaporates into the sky.

A cloud contains many particles that absorb moisture, and precipitation drops are often formed as a result of these particles absorbing water.

These water droplets, that is, rain, coming down from clouds are usually 0.5 millimeters in diameter.

Additionally, before a raindrop lands on the ground, it moves hundreds of times towards its surface as it moves across the sky. may attract small aerosol particles. Coagulation is the process of droplets and aerosols attracting each other, making the drops larger.

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

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

Additionally, the air around a drop slows it down when it starts moving faster.

In this case, even the smallest raindrop may not fall to the ground because the rising air current keeps it in place and It pushes up until it’s big enough to fall down.

Again, some raindrops may sometimes hit each other. When this collision occurs, some stick together and form a large drop, while others break up into smaller drops. As the number of drops increases, The amount of rain also increases.

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