How heavy do clouds have to be to rain?

How heavy is a cloud before it rains?

According to scientists, the weight of the average cumulus cloud is 1.1 million pounds! Think about that for a moment. This means that at any given moment, there are millions of pounds of water floating above your head. That’s the equivalent of 100 elephants.

Do all clouds lead to rain?

We know that not all clouds produce rain that strikes the ground. Some may produce rain or snow that evaporates before reaching the ground, and most clouds produce no precipitation at all. When rain falls, we know from measurements that the drops are larger than one millimeter.

What type of clouds cause heavy rain?

If enough atmospheric instability, moisture, and lift are present, then strong updrafts can develop in the cumulus cloud leading to a mature, deep cumulonimbus cloud, i.e., a thunderstorm producing heavy rain.

Can it rain without a cloud?

Because rain forms when droplets of condensed moisture grow large enough to descend quickly into the air, their absence can make it impossible for rain to occur. That means if there are no clouds overhead, rain cannot happen as well.

Can a cloud burst?

Cloudbursts are infrequent as they occur only via the ‘orographic lift’ or occasionally when a warm air parcel mixes with cooler air, resulting in sudden condensation. The term ‘cloudburst’ was coined from the notion that clouds were akin to water balloons and could burst, resulting in rapid precipitation.

Can you touch a cloud?

Well, the simple answer is yes, but we will get into it. Clouds look like they would be fluffy and fun to play in, but they are actually made of trillions “cloud droplets”. … Nonetheless, if you were to be able to touch a cloud, it wouldn’t really feel like anything, just a little wet.

Why are clouds black before rain?

Clouds usually appear white because the tiny water droplets inside them are tightly packed, reflecting most of the sunlight that hits them. … When it’s about to rain, clouds darken because the water vapor is clumping together into raindrops, leaving larger spaces between drops of water.

What happens to clouds that don’t rain?

Thin, wispy clouds like these usually don’t produce rain or other types of precipitation. … For example, if there aren’t enough droplets of water in a cloud to collide and form large drops, the tiny droplets will stay suspended in the air and it won’t rain.

Why are clouds dark at night?

The tiny water droplets and ice crystals in clouds are just the right size to scatter all colors of light, compared with the smaller molecules of air that scatter blue light most effectively. … As their thickness increases, the bottoms of clouds look darker but still scatter all colors. We perceive this as gray.

What is the highest cloud ever recorded?

They are the highest clouds in Earth’s atmosphere, located in the mesosphere at altitudes of around 76 to 85 km (249,000 to 279,000 ft).

Noctilucent cloud.

Classification Other

Which cloud is not a high level cloud?

Low-level clouds (0-2 km): stratus, cumulus, cumulonimbus, and stratocumulus.

Can cumulus clouds produce rain?

Normally, cumulus clouds produce little or no precipitation, but they can grow into the precipitation-bearing congests or cumulonimbus clouds. Cumulus clouds can be formed from water vapour, supercooled water droplets, or ice crystals, depending upon the ambient temperature.

Why are there no clouds in Arizona?

There’s constantly high air pressure over Arizona because it’s so hot too. Due to the high pressure, air sinks down, which means clouds can’t form. Since there’s no rain, there’s no humidity, but that just means the dry air heats up faster without any humidity to absorb heat.

Is lightning possible without clouds?

Dry lightning is lightning that occurs without rain nearby. … These lightning flashes have been documented to travel several miles away from the thunderstorm cloud. They can be especially dangerous because they appear to come from clear blue sky.

Can it rain fish?

Yes. Although rare, there are numerous instances of fish falling down from the skies. Of course, the fish do not really “rain” in the sense of condensing out of water vapor. … All sorts of creatures have been reported raining down, including snakes, worms, and crabs, but fish and frogs are the most common.
