How do water droplets in clouds get bigger?

How do water droplets in clouds get bigger?

Turbulent currents in the clouds provide the first collisions between droplets. The combination forms a larger drop which can further collide with other droplets, thus growing rapidly in size. As the drops grow, their fall velocity also increases, and thus they can collide with slower falling droplets.

When water droplets get large enough to fall from the clouds it’s called?

Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.

What happens when rain falls to the Earth’s surface?

When precipitation falls over the land surface, it follows various routes in its subsequent paths. Some of it evaporates, returning to the atmosphere; some seeps into the ground as soil moisture or groundwater; and some runs off into rivers and streams.

How cloud droplets turn into rain droplets?

Water vapor in the atmosphere cools and condenses on a particle, such a dirt, dust or soot. This creates a cloud and when the cloud becomes saturated (full of moistures), water is released as raindrops.

How does rain fall from the clouds?

Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.

Do oceans get rain?

Since the oceans contain about 97 percent of Earth’s surface water, they make the biggest contribution to evaporation. Most of that water rains back into the oceans — only about 10 percent of it falls on the land.

What happens to water droplets when they fall out of clouds?

Water droplets may grow as a result of additional condensation of water vapor when the particles collide. If enough collisions occur to produce a droplet with a fall velocity which exceeds the cloud updraft speed, then it will fall out of the cloud as precipitation.

How do droplets of water form in the air?

WARMER water vapour from the surrounding air comes into contact with the COOLER surface of the object, LOSES HEAT to it and CONDENSES to form water droplets. I’d like you to pay special attention to the bolded keywords above.

When does a droplet become a raindrop?

Soon the droplet is so heavy that the cloud (or the room) can no longer hold it up and it starts falling. As it falls it eats up even more droplets. We can call the growing droplet a raindrop as soon as it reaches the size of 0.5mm in diameter or bigger.

What is the size of a droplet of water?

Each particle (surrounded by water) becomes a tiny droplet between 0.0001 and 0.005 centimeter in diameter. (The particles range in size, therefore, the droplets range in size.)
