What is the common range for transport winds?

Explanation:
Transport winds are the winds that move embers and smoke away from the main fire, shaping how far a spot fire can travel and how the fire behaves along its edges. In practical burn planning, a moderate wind range is commonly used because it provides enough airflow to carry embers without making the fire uncontrollable. That range is about 9 to 20 mph. At these speeds, embers can travel a noticeable distance, so you can anticipate spotting and plan patrols and containment accordingly. Winds weaker than this tend to limit ember transport, while winds stronger than this greatly increase spotting risks and complicate control. So the typical, commonly cited range for transport winds is 9–20 mph.
