Why are the fires in California so hard to put out? |
Words "small fire on people, depends on the fire," said Sun Long, fires and earthquakes, belong to the natural disaster such as mud-rock flow, with huge energy release, the fire situation changing, unpredictable, especially under the condition of strong wind, as special fire behavior occurs, rapid expansion of fire fire evolved into crown fire, fire fighters and helicopters cannot close to the fire, large fire equipment cannot enter the mountain to participate in the fire.
It is extremely dangerous and that manpower is largely unattainable, and it is difficult to fight and to extinguish the fire by merely provide an isolated zone from the periphery, fire by fire, etc., or by waiting for weather condition to change (by natural forces rather than by man).
_ just saw the news and several times later, feel is not like gone with the wind is the film company performance? Because I think a lot of news in the world is fake, like what the movie shows me, how can it be true? So many people died, burned so many mountain houses, also did not see the death picture not quite believe. And there are many human disasters that cannot be believed, just like world war I and world war ii. Maybe you can't understand the human disaster without drowning! If you think about drowning, human death in a second, it's not impossible. Just wondering, when will human suffering end?
美国加州大火为何难以扑灭?|
话说“小火靠人,大火靠天”,孙龙说,山火和地震、泥石流等同属自然灾害,伴随着巨大的能量释放,火场情况瞬息万变,难以预测,尤其在大风条件下,当特殊火行为发生,火场迅速扩大,火灾演变为树冠火,消防员及直升机都无法靠近火场,大型消防器械也无法进入山地参与灭火.
这种情况极度危险且人力基本不可及,难以扑救,只能采取从外围开设隔离带、以火攻火等手段,或者等待天气条件改变(靠自然力而非人力)才能灭火。
_刚看到这个新闻和以后几次,都觉得不会就是像乱世佳人那样是电影公司表演的吧?因为世界的很多新闻我都觉得是假的,像是电影演给我看的,怎么会是真的呢?死那么多人,烧那么多山房,也没看到死亡图片不太相信。还有那很多人类灾难不敢相信是真的,如同一战二战一样。也许你没有溺水就无法体会人类的灾难吧!想想溺水,人类死亡也就一秒钟的事情,那么这些是真的也不是没可能。只是很想明白,人类的苦难何时可以结束?
