The difference between depressions and cases of atmospheric instability, and how they occur and predict them?

Weather of Arabia - the difference between depressions and atmospheric instability, and how they occur and predict them?

The video explains the difference between depressions and atmospheric instability, as not understanding such weather terms leads to confusion in understanding the weather forecast and what may result from such weather phenomena.

Below is a simple explanation of the difference between a depression and a state of atmospheric instability

What is a depression?

The depression is formed in certain regions and moves to other regions on a regular basis, as it brings with it certain weather phenomena such as rain, winds, and low temperatures.

Example :

When an air depression affects an area in Jordan or approaches Jordan, it moves from another area and can be seen via satellite images, moving, for example, from the central Mediterranean to the eastern Mediterranean towards the Kingdom.

These weather phenomena are accompanied by regularity in the nature of their movement. For example, rain falls initially in the north, then moves to the center, and then moves to the southern regions of the Kingdom.

What is the state of atmospheric instability?

Atmospheric instabilities are formed in a different way, in a specific geographical area where hot air from the lower layers of the atmosphere converges with cold air from the upper layers of the atmosphere with the presence of some moist currents available in the atmosphere, what is called a state of atmospheric instability arises, this state of instability Atmospheric clouds lead to the formation of the so-called cumulus clouds. These cumulus clouds grow vertically into high layers of the atmosphere and are thick in height, and lead to the occurrence of four or five weather phenomena.

Weather phenomena associated with atmospheric instability:

• Thunderstorms .
• Heavy rain, and may be in a short period of time.
• Downward winds, strong winds.
• Sandstorms .
• Showers of hail, sometimes of a large size

The state of atmospheric instability leads to the formation of these clouds in geographically narrow ranges and is not comprehensive, such as depressions.
