Weather seems to be the most important factor dictating the severity of forest fires.

天氣似乎是決定森林火災嚴重程度的最重要因素。 天氣似乎是決定森林火災嚴重程度的最重要因素。

 Hot, dry weather lowers the moisture content of fuel. 

 炎熱，乾燥的天氣會降低燃油的含水量。

Once a fire has started, wind would become influential concerning oxygen supply and the rate of spread.

一旦火災開始，風將對氧氣供應和傳播速度產生影響。

Other important factors include forest types and forest conditions.

其他重要因素包括森林類型和森林狀況。

For example, fire is more likely to occur in conifers than in hardwoods; slash-covered or brushy areas are especially hazardous because the rate at which combustion consumes fuel is related to fuelvolume or surface area. 

例如，在針葉樹中比在硬木中更容易發生火災; 斜面或刷毛區域特別危險，因為燃燒消耗燃料的速率與燃料體積或表面積有關。

Some fires are caused by lightening; others are caused by people. 

一些火災是由減輕引起的; 其他是由人造成的。

Those caused by people may be accidental or intentional. Regional differences exist regarding the causes of fire. 

由人造成的可能是偶然的或故意的。 有關火災原因的區域差異。

For example, fires in Rocky Mountains present a different picture from the fires in the South. 70 percent of the fires in the former area are caused by lightening, whereas intentional fires take up to 40 percent in the later.

例如，洛磯山脈的火災與南方的火災呈現出不同的畫面。 前者地區70％的火災是由減輕引起的，而故意的火災則在後者中佔40％。
