Typhoon Amy trajectory analysis
Track and Movement Characteristics
Typhoon Amy (199107) formed at Northwest Pacific洋面, 初始Position位 at 13°N, 138°E. 在整个生命史中, 该Typhoon 呈现出稳定的NW toward MovingTrend, 未出现明显的路径转折或停滞现象. 从经纬度变化来看, Typhoon 中心持续 toward WNW direction推进, 纬度由13°N逐步上升至26°N, 经度由138°EW移至111°E. 这种长About 离, 单 toward 性的Moving路径表明其受副热带高压引导气流影响显著, 路径较为平直. 值得注意的是, 尽管Moving跨度较大, 但全程无Landfall记录, 始终在海上活动, 最终在较高纬度海域减弱消散.
Intensity Evolution and Peak Status
Amy的Intensity演变经历了典型的“快速增强—巅峰维持—迅速减弱”过程. formed初期为Tropical Depression, 气压1005hPa, wind speed12m/s. 在7月16日至7月18日期间, 系统经历爆发式增强, 气压在48h内骤降60hPa至945hPa, wind speed提升至45m/s, 升级为Severe Typhoon. 7月19日02:00, Typhoon 达到巅峰状态, 中心最低气压降至930hPa, max wind 达55m/s, 定性为Super Typhoon. 然而, 巅峰状态维持Time极短, 仅6h后气压即回升至940hPa, wind speed回落. 随后Go to 快速减弱期, 至7月20日14:00结束时, 已 weakened into Tropical Depression, 气压回升至995hPa, wind speed降至12m/s. 这种短Time内剧烈的气压波动反映了其核心结构对环境垂直风切变或海温变化的敏感性.
Comparison of Typhoon
In the sequence of storms named Amy, 1991 stood out for its exceptional intensity. Compared with the same-named typhoons of 1994, 1977, and 1974, whose peak intensities were only tropical storms or severe tropical storms, with minimum pressures above 985 hPa, Amy was far stronger in 1991, reaching 930 hPa. Only Amy of 1971, identified as 197104, reached super typhoon status, with a minimum pressure as low as 895 hPa and an intensity exceeding that of Amy in 1991. Overall, Amy in 1991 was among the strongest typhoons bearing this name. Its peak intensity ranked second only to the same-named typhoon of 1971 and was significantly greater than that of other storms in the naming sequence.
