Cross-current refers to a current that flows in a different direction from the main current, causing water turbulence. A few synonyms for "cross-current" are counterflow, crossflow, and eddy. Counterflow is when a current moves opposite to another current, creating a disturbance. Crossflow generally refers to a current that flows at different angles to the primary flow. An eddy is a spinning current that moves in a circular motion around a central point. Additionally, terms such as intersection, collision, or opposition can describe scenarios where different currents meet and interfere. Understanding the synonyms for cross-current can help describe complex water flows more precisely.
