Why do clouds form over the central part of South Africa?
The warm air ascends along the boundary while the cold air sinks below it. If there is enough humidity, the upward motion leads to condensation and to the development of clouds and precipitation.
What are the three main cloud formations?

What are some unusual cloud formations?
- Lenticularis. These smooth, oval-like shaped clouds, officially named altocumulus lenticularis clouds, are believed to be one of the most common reasons behind sightings of UFOs.
- Nacreous clouds.
- Arcus. Roll cloud (Eazydp/Wikimedia)
- Virga.
- Mackerel Sky.
- Mammatus.
- Fallstreak holes.
- Kelvin-Helmholtz wave.
What are the formations of clouds?
Clouds form when the invisible water vapor in the air condenses into visible water droplets or ice crystals. For this to happen, the parcel of air must be saturated, i.e. unable to hold all the water it contains in vapor form, so it starts to condense into a liquid or solid form.
What is the basic pattern of air movement over South Africa?
Coastal Low Pressure Systems: Coastal Low pressure systems develop during summer and winter in SA. These low pressure sytems cause complete different weahter on either side of the pressure cell. The air moves in a clockwise direction around the cell.
How Berg winds are formed?
Bergwinds usually occur when a strong high pressure exists south or south-east of the country and when a high pressure is also situated over the country. These conditions usually only occur in winter, but sometimes in summer too, hence bergwinds are mainly a autumn-winter-spring phenomenon.
How many cloud formations are there?
According to the World Meteorological Organization’s International Cloud Atlas, more than 100 types of clouds exist. The many variations, however, can be grouped into one of 10 basic types depending on their general shape and height in the sky.
What are the 4 main cloud?

How are clouds formed Class 5?
Clouds are made up of tiny water droplets or ice crystals. Clouds are formed when warm air rises, expands and then cools. This cool air can’t hold as much water vapor as the warm air. The vapor will then begin to condense and form itself around dust particles that are floating in the air.
