A cyclone is fundamentally characterized by a low-pressure system. In meteorological terms, cyclones occur when air flows inward towards a low-pressure center, creating a spiraling effect. The nature of this low-pressure area leads to rising air, which often causes the development of clouds and precipitation as the air cools and condenses.

The low pressure at the center of a cyclone is instrumental in driving the atmospheric conditions associated with it, such as strong winds and storm systems. Additionally, cyclones can lead to various weather phenomena, including severe storms, depending on their intensity and the moisture they contain.

High-pressure systems, in contrast, are linked to descending air and typically result in clearer and calmer weather conditions, while stable pressure refers to conditions with minimal variations in atmospheric pressure. Variable pressure may imply shifts and fluctuations but does not denote the consistent low-pressure system characterizing cyclones. Understanding this fundamental aspect of cyclones aids in interpreting weather patterns for safe aviation operations.
