appearance as argument number 1
-------------------------


(documentation EFScaleAttribute ChineseLanguage "EFScaleAttribute 是改良藤田级数的简称。这是根据一系列龙卷风所造成的损害, 估计首灾区的3秒阵风风速来表示一个 Tornado (龙卷风)的强度。级数最低的龙卷风为 EFO,它的阵风风速估计在 65 到 85 mph 之间, 而最强级别的 Tornades 是 EF5,阵风大于 GreaterThan 200 mph。") Weather.kif 2067-2069
(documentation EFScaleAttribute EnglishLanguage "EFScaleAttribute is short for the Enhanced Fujita Scale. It is the Attribute for indicating the intensity of a Tornado according to a set of 3-second gusts wind estimates based on damage it caused. The lightest tornados(EFO) have wind gusts ranging between 65 to 85 mph,and the severest Tornades (EF5) GreaterThan 200 mph.") Weather.kif 2062-2066
