What is a Category 5 hurricane? What do hurricane categories mean? That is where the National Hurricane Center comes in.

什么是5级飓风? 飓风的分级代表什么意思? 这就是国家飓风中心的作用所在。

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed. The scale does not take into account other potentially deadly hazards such as storm surge, rainfall flooding and tornadoes.

萨菲尔-辛普森飓风风力等级是一个1到5等级,仅基于单一飓风的最大持续风速(进行分级)。这个等级没有考虑到其他潜在的致命危险,如风暴潮、降雨量、洪水和龙卷风。

The Saffir-Simpson Hurricane Wind Scale estimates potential property damage. While all hurricanes produce life-threatening winds, hurricanes rated Category 3 and higher are known as major hurricanes. Major hurricanes can cause devastating to catastrophic wind damage and significant loss of life simply due to the strength of their winds. Hurricanes of all categories can produce deadly storm surge, rain-induced floods and tornadoes. These hazards require people to take protective action, including evacuating from areas vulnerable to storm surge.

萨菲尔-辛普森飓风风力等级估计潜在的财产损失。虽然所有飓风都会产生危及生命的风,但三级及以上的飓风被称为大型飓风。仅由于其风力强度,大型飓风就会造成毁灭性的灾难性风力破坏和重大的生命损失。所有等级的飓风都能产生致命的风暴潮、雨水引发的洪水和龙卷风。这些危害需要人们采取保护措施,包括从易受风暴潮影响的地区撤离。

"Herbert Saffir, a civil engineer from Florida, and Dr. Robert Simpson, director of the NHC from 1967-74, created this classification scale to categorize hurricanes by the types of damage that typically occur at various sustained wind speeds. Saffir initially developed the scale in 1969, and it would later be expanded by Simpson and published under the Saffir-Simpson name in 1973," FOX Weather reports.

据福克斯天气报道。“来自佛罗里达州的土木工程师赫伯特·萨菲尔(Herbert Saffir)和1967年至1974年担任国家飓风中心主任的罗伯特·辛普森(Robert Simpson)博士创建了这个分级表,根据通常在不同持续风速下发生的破坏类型对飓风进行分类。萨菲尔最初在1969年开发了这个量表,后来辛普森对其进行了扩展,并于1973年以萨菲尔-辛普森的名义出版。”
