What phenomenon describes sparks or embers being carried by the wind to ignite new fires?

The phenomenon that describes sparks or embers being carried by the wind to ignite new fires is known as spotting. Spotting occurs when the wind transports burning materials, such as embers or sparks, away from the original fire. These materials can land on combustible vegetation and ignite new fires, often at considerable distances from the main fire front. This can substantially increase the fire's spread and complicate firefighting efforts, as it creates multiple ignition points that firefighters must manage.

Crown fire refers to a fire that spreads through the tops of trees, typically in conditions of strong winds and dry foliage. A flare-up describes a sudden increase in fire activity within a specific area, usually due to a change in environmental conditions, while a backing fire involves a fire that is moving against the wind or down a slope, which is typically slower and less intense than other types of fire spread. Understanding spotting is crucial in wildland fire management as it highlights the importance of wind conditions in fire behavior and spread.
