Q: What is a depression and how can it be correctly defined?

Arab Weather - A low pressure system is an area of the atmosphere where the air pressure is lower than the surrounding areas. A low pressure system forms when warm air rises, causing a decrease in air pressure at the Earth's surface. As the air rises, it cools and the water vapor in it condenses, leading to cloud formation and sometimes precipitation.

A depression can be correctly defined as:

An area of relatively low atmospheric pressure compared to its surroundings, where air rises, causing moisture in the atmosphere to condense and clouds to form, which may result in weather disturbances such as rain and strong winds.

Depressions are often associated with unstable weather conditions, including rain and wind, and their severity depends on factors such as the degree of pressure variation and the presence of moisture in the air.
