Typhoon Amy (199107) 的生命史始 at Northwest Pacific远洋海域, formed初期呈现稳定的W行Trend. 从1991年7月12日18时在(11.2°N, 146.7°E) formed至7月15日期间, 系统主要沿纬 toward toward WMoving, The latitude变化微小, During从146.7°E快速W移至134.5°E, 显示出受低层信风引导的显著特征. 7月16日起, 路径开始发生明显转折, Moving direction由纯W toward 逐渐转为NW toward . 随着纬度从16.2°N攀升至25.1°N, 经度持续W进至112.4°E, 表明副热带高压脊线Position及中纬度W风带气流对typhoon track产生了total 同影响. 整个生命周期内, Typhoon 未Landfall任何陆地, 最终在S海N部或近海区域减弱消散, 全程保持海上活动状态.
Amy的Intensity演变呈现出典型的“缓慢积累, 爆发增强, 迅速衰减”特征. formed初期长达三天维持NamelessIntensity (wind speed7-12m/s) , 7月16日升级为Tropical Storm后Go to 快速增强期. 特别是在7月17日至18日期间, max wind 从33m/s激增至64m/s, 达到Super Typhoon级别, 中心附近最大wind force极具破坏性. 然而, 巅峰状态维持Time较短, 7月19日06时wind speed已降至53m/s, 随后在12h内急剧 weakened into Tropical Storm (23m/s) , 显示其结构在后期受到强烈环境因素干扰而崩溃.
In 1994, the same name Typhoon peak intensity in 1977 and 1974, respectively only Tropical Storm, Tropical Storm and Severe Tropical Storm, did not reach the level of Typhoon and above. only 1971 Amy (197104) had reached the level of Super Typhoon, with 1991 Amy belonging to high intensity instances.
