Amazing And Fascinating Facts About Clouds(Interestingawesome.blogspot.com)
Clouds are amazing. Most of them
are like cotton balls. Their endless shapes can add beauty to the atmosphere
and to the nature. Normally a cloud is water vapor in the atmosphere (sky) that
has condensed into very small water droplets or ice crystals that appear in
visible shapes or formations above the ground. Earth is not the only planet
that have cloud, some planet in our solar system have clouds. Also there are
some amazing clouds in our galaxy which are bigger than our earth and one of
them is made out of liquor. Very interesting huh? So, here are some crazy facts
about clouds that will make you say WOW..!!!

- Water
on the Earth evaporates (turns into an invisible gas) and rises up into the
sky. Higher up where the air is colder, the water condenses : it changes from a
gas to drops of water or crystals of ice . We see these drops of water as
clouds. The drops fall back down to earth as rain, and then the water
evaporates again. This is called the " water cycle".
- The atmosphere always has some water vapor. Clouds form when the
atmosphere can no longer hold all the invisible air vapor. Any more water vapor condenses into very
small water drops.
- Clouds are heavy. The water in a cloud can have a mass of several million
tons. Every cubic meter (m3) of the cloud has only about 5 grams of water in
it. Cloud droplets are also about 1000 times heavier than evaporated water , so
they are much heavier than air.
- They do not fall, but stay in the air, because there is warm air all
round the heavier water droplets. When water changes from gas to droplets, this
makes heat. Because the droplets are very small, they "stick" to the
warm air.
- Sometimes, clouds appear to be brilliant colors at sunrise or sunset.
This is due to dust particles in the air.
- Since clouds are made out of the tiniest possible droplets of water and
ice when pilots pass through them with their planes they do not see nothing but
clouds.
- Clouds are classified according to how they look and how high the base of
the cloud is in the sky.
- There are five basic families of clouds based on how they look. They are,
Cirrus clouds, Straturs Clouds, Stratocomulus Clouds, Cumulonimbus Clouds and
Cumulus Clouds.
- Cirrus clouds are high and thin. The air is very cold at high levels, so
these clouds are made of ice crystals instead of water droplets. This is a picture of a Cirrus Cloud.
- Stratus clouds are like flat sheets. They may be low-level clouds (
stratus), medium-level ( altostratus), high-level (cirrostratus ), or thick
multi-level clouds that make rain or snow ( nimbostratus ). this is a Stratus cloud.
- Stratocumulus clouds are in the form of rolls or ripples. They may be
low-level clouds (stratocumulus), medium-level (altocumulus), or high-level
(cirrocumulus ). Here is a Stratocumulus cloud.
- Cumulus clouds are puffly and small when they first form. They may grow
into heap clouds that have moderate vertical extent (nothing added to the
name), or become towering vertical clouds ( towering cumulus).
- Cumulonimbus clouds are very large cumulus-type clouds that usually
develop cirrus tops and sometimes other features that give them their own
unique look.This is a Cumulus cloud.
- There are three basic families of clouds based on how high they are. They
are High level Clouds, Meadium Level Clouds and Low Level Clouds.
- High clouds form from 10,000 to 25,000 ft (3,000 to 8,000 m) in cold
places, 16,500 to 40,000 ft (5,000 to 12,000 m) in mild regions and 20,000 to
60,000 ft (6,000 to 18,000 m) in the very hot tropics . They are too high and
thin to produce rain or snow.
- Middle clouds usually form at 6,500 ft (2,000 m) in colder areas.
However, they may form as high as 25,000 ft (8,000 m) in the tropics where it's
very warm all year. Middle clouds are usually made of water droplets but may
also have some ice crystals. They occasionally produce rain or snow that
usually evaporates before reachin the ground.
- Low-level clouds are usually seen from near ground level to as high as
6,500 ft (2,000 m). Low clouds are usually made of water droplets and may
occasionally produce very light rain, drizzle, or snow.
- These are clouds of medium thickness that can form anywhere from near
ground level to as high as 10,000 ft (3,000 m). These clouds called as Moderate
Vertical Clouds. The tops of these clouds are usually not much higher than
20,000 ft (6,000 m). Vertical clouds often create rain and snow. They are made
mostly of water droplets, but when they push up through cold higher levels they
may also have ice crystals.
- Towering Vertical clouds are very tall with tops usually higher than
20,000 ft (6,000 m). They can create heavy rain and snow showers. Cumulonimbus,
the biggest clouds of all, can also produce thunderstorms. These clouds are
mostly made of water droplets, but the tops of very large cumulonimbus clouds
are often made mostly of ice crystals.
- Some scientists believe how the properties of clouds can help predict the
upcoming climate change effects. Also clouds reflect a significant proportion
of solar radiation back into space.
- When we see white clouds in the sky this really means that we are looking
at dense deep clouds that exhibit a high reflectance (70% to 95%) so they appear
white.
- The lead generated by human activities is causing clouds to form at
warmer temperatures, since the temperatures are warmer that means there is less
water in the clouds. In years to come this trend could significantly alter the
pattern of both rain and snow in a warmer world.
- As mention above, Cumulonimbus are the biggest clouds, located at around
9.7 kilometers (6 miles) above us. These clouds are believe to hold up to half
a million tons of water.This is a picture of one of them.
- The average cloud droplet is .02 mm in diameter, about five times smaller
than the thickness of a sheet of paper. These droplets condense to form clouds
up to 14 miles tall, which would be the same height as fifty Empire State
Buildings piled on top of each other.
- The cloudiest place on earth is South Africa’s Prince Edward Islands in the Antarctic Indian Ocean. Parts
of the islands see just 800 hours of sunshine all year. To put that in context,
it’s much less than the 4,019 hours that
Yuma, Arizona,otherwise known as the sunniest
place on earth, experiences annually.
- A number of countries including
China, France, Australia and the United States are attempting to control the
weather through cloud seeding. This process artificially induces cloud
formation by injecting iodide or carbon dioxide into the atmosphere. China
claims that it has seen its earliest snowfall since the 1980s due to cloud
seeding, but this process is creating political conflict between neighboring
regions, which are accusing each other of “stealing
rain.”
- Noctilucent clouds seemed to first appear after the 1883 eruption of
Krakatoa and are now a common sight.
- Sagittarius B is a vast molecular cloud of gas and dust floating near the
center of the Milky Way, 26,000 light-years from Earth, 463,000,000,000 kilometers
in diameter and, amazingly, it contains 10-billion-billion-billion liters of
alcohol. And it is 1,000 times larger than our solar system.
- Astronomers have found a massive water vapor cloud which holds 140
trillion times the mass of water in the Earth’s
oceans somewhere around 10 billion light years away, making it the largest
discovery of water ever found.
- Other
planets in our Solar System have clouds. Venus has thick clouds of
sulfur-dioxide while Jupiter and Saturn have clouds of ammonia.
