ember attackとは 意味・読み方・使い方

An ember attack is a naturally occurring event. During a bushfire, burning parts of trees such as twigs, branches or leaves become temporarily airborne and can be carried away upwind of the bushfire. An 'ember attack' occurs when many embers are carried by winds in a cluster. The Stringybark species of Eucalypt is particularly notorious for contributing large flaming sections of bark that due to their size, weight and shape, can be carried up to several kilometres away. The movements of embers from a bushfire are the primary cause of spotfires, which contribute to the continued spread of a bushfire.
