Potential vorticity is a fundamental property in fluid dynamics that combines the conservation of vorticity and stratification, crucial for understanding atmospheric and oceanic circulations. It remains constant for an air parcel in the absence of external forces, making it a powerful tool for predicting the evolution of large-scale weather patterns and ocean currents.

Stratification refers to the hierarchical arrangement of individuals or groups in a society, often based on factors like wealth, power, race, or education. It plays a crucial role in shaping access to resources and opportunities, influencing social mobility and perpetuating inequality.

An air parcel is a theoretical volume of air used in meteorology to understand atmospheric processes, assuming it moves without exchanging mass or energy with its surroundings. This concept helps in analyzing weather phenomena like cloud formation, stability, and convection by simplifying the complex interactions in the atmosphere.

External forces are influences originating outside a system that can affect its behavior, performance, or structure. They play a crucial role in fields like physics, economics, and business, determining how systems interact with their environments and adapt to changes.

Ocean currents are large-scale movements of water within the world's oceans, driven by factors such as wind, temperature, salinity differences, and the Earth's rotation. They play a crucial role in regulating global climate, distributing heat, and supporting marine ecosystems.
