What is a wind rotor?

• A. Calm air behind a building
• B. Still air in a valley
• C. Rotating air behind a large object
• D. Stable air at high altitudes

Answer: (C)

A wind rotor refers to a phenomenon in which air swirls or rotates around an object, typically occurring behind a large obstacle such as a building, hill, or mountain. This condition arises due to the disruption of smooth airflow caused by the obstacle, where the wind flows around it and creates turbulent air patterns. When the wind encounters the large object, it can create a rotating motion in the air behind the object, resulting in a wind rotor effect. This understanding is crucial for pilots because it can impact aircraft performance and handling in the vicinity of these obstructions, especially when taking off or landing. Recognizing the presence of wind rotors and their potential effects on flight helps pilots make informed decisions to ensure safety and maintain control of the aircraft.
