Although seawalls and levees are valuable protection measures for coastal cities, even they are no guarantees of safety, as events in Galveston and New Orleans showed.

海墙和岸堤虽然是有价值的海岸城市保护设施,但是像GalvestonNew Orleans那些事件所显示的那么样,它们并不保障安全。

 

Hurricane Katrina caused shocking misery and ruin; the Louisiana Superdome (top) became a tenuous refuge, while much of the surrounding land was left devastated. (bottom).

Katrina飓风造成了惊人的悲伤景象和废墟;上图的Louisiana Superdome只是个单薄的避难所,它周遭的土地,大范围地被摧毁掉(下图)。

 

Appendix.

Who were SAFFIR and SIMPSON?

Hurricane strength is described by the Saffir-Simpson Scale. Herbert Saffir was a consulting engineer who, in the 1960s, helped write design requirements for buildings in the Miami, Florida, area. He also ---

 

附属文件。

Saffir是谁?Simpson又是谁?

飓风的力道由Saffir-Simpson Scale(表)示出。

 

Herbert Saffir是一位咨询工程师,他在1960年代,协助写出在Miami, Florida地区的建筑物的设计之所需。他也有在1971年,为联合国写出一份,使用一份表格(和地震报告使用的表格相同。)的报告,叙述了高风速对便宜住宅的效应。

 

Robert SimpsonMiamiNational Hurricane Center的主管,任职从1967年到1973年。有了1969年的飓风Camille,他成为第一位预告者,负责正确地预告一场飓风的风速和暴雷雨的冲击水平。他把那些成分加进Saffir的风造损坏表里。

 

Wilma Sets the Bar Low.

Because wind instruments tend to get blown away in hurricanes, scientists calculate the storms’ strength using air pressure, which they measure from aircraft or devices dropped into the storm. The greater the drop in air --- 

飓风Wilma的气压低。

因为测风器具惯例地要被飓风吹走,科学家们使用气压计算暴雷雨的力道;那是在飞机上,或者使用丢进暴雷雨里的器械量度的。气压下降得愈大,风走得愈快。气压或以吋,气压计的水银barmillibarmb)量度。海平线的标准气压是水银柱的29.92英寸(74.8 cm),或者大约一柱(bar)或1013.2 mb2005年的飓风Wilma有个26.05 882 mb的中心气压计气压,那是大西洋飓风之中最低的了。飓风Wilma的风眼也是被研究过,大西洋龙卷风之中最小的。
