Clouds form when water evaporates into the sky and rises as vapor. There are three levels of clouds - low, mid, and high level clouds. Low level clouds include cumulus clouds, which are puffy and cotton-like, and fog clouds. Mid-level clouds consist of alto cumulus and alto stratus clouds. High level cirrus clouds are thin and wispy ice crystal clouds.
Clouds
What are clouds?
A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.
Why do clouds float?
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
There are 3 main types of clouds:
Cirrus or thin feathery clouds
Stratus or layered clouds
Cumulus or fluffy clouds
Cirrus Clouds
Are the most common of the
high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours.
Stratus Clouds
are uniform grayish clouds that often cover the entire sky. They resemble fog that doesn't reach the ground. Light mist or drizzle sometimes falls out of these clouds.
Cumulus Clouds
are white, puffy clouds that look like pieces of floating cotton. Cumulus clouds are often called "fair-weather clouds". The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
The Importance of Clouds
Clouds help regulate Earth's energy balance by reflecting and scattering solar radiation and by absorbing Earth's infrared energy.
Clouds are required for precipitation to occur and, hence are an essential part of the hydrologic cycle.
Clouds indicate what type of atmospheric processes are occurring (e.g., cumulus clouds indicate surface heating and atmospheric turbulence).
Clouds help redistribute extra heat from the equator toward the poles.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

2. HOW CLOUDS ARE FORMED
Clouds are formed when water evaporates into the sky. This
vapor rises into the sky and that is what causes clouds to
form.
3. TYPES OF CLOUDS
There are very many types of clouds. They are sorted into
three levels. Low level, Mid level, and High level.
4. CUMULUS
A cumulus is a low level puffy cloud. It is a cotton like cloud that is
big, puffy, and white. It is a sign of good weather you will usually
see it in the summer time. It looks like this.
5. FOG
Fog is considered a low level cloud as well. Fog forms on
the ground in cities. It is formed the same way as other
clouds. It looks like this.
6. Alto cumulus clouds are found in the mid level in
between 2000-6000 meters. These mid level
clouds are mostly just water droplets. These
clouds are just like cumulus clouds except higher
up in the sky.
7. ALTO STRATUS
Alto Stratus clouds are mid level clouds. They are just
like a big blanket of cloud. These clouds are usually grey
but can be white They look like this.
8. CIRRUS
Cirrus clouds are thin and wispy clouds. Cirrus
clouds are composed of ice crystals. They are usually
a sign of fair weather and point the direction of the
wind. This is what they look like.
9. INTERESTING FACTS
A cloud is a large group of tiny water droplets that we can see in
the air.
Clouds can contain millions of tons of water.
Other planets in our Solar System have clouds. Venus has thick
clouds of sulfur-dioxide.
If we didn’t have any clouds there would be no rain, hail, or snow.
