Wildland Firefighting Practice Exam

Question: 1 / 400

Which type of canyons typically experience more independent wind currents?

Wide canyons

Narrow canyons

Narrow canyons tend to experience more independent wind currents due to their restricted geometry. When wind flows through a narrow space, it can accelerate and create turbulence as it interacts with the canyon walls. This can lead to the formation of localized wind patterns that can be quite different from the general atmospheric winds outside the canyon.

Additionally, the shape of narrow canyons can channel and direct winds in unpredictable ways, resulting in gusts and eddies that are not present in wider or flatter canyons. This phenomenon makes narrow canyons particularly significant in wildfire behavior, as these independent wind currents can affect the spread and intensity of fires. Understanding these wind patterns is critical for effective fire management and suppression strategies.
