Track and Movement Characteristics

Typhoon Harriet (197110) at 1971年6月30日08时在Philippines以E洋面 formed, 初始Position为8.8°N, 136.9°E. 在其全生命周期内, 该Typhoon 整体呈现稳定的NW toward MovingTrend, 未出现明显的路径转折或异常摆动. 从经纬度坐标序列分析, 系统自 formed后持续 toward WNW direction推进, 纬度从8.8°N逐步上升至19.6°N, 经度从136.9°EW移至104.1°E, 横跨跨度超过30个经度. 值得注意的是, 尽管其Moving direction保持一致, 但移速在不同阶段存在差异: 在7月2日至7月5日期间, 系统快速穿Vietnam海N部海域, 经度变化显著; 而在生命末期 (7月7日至8日) , 随着纬度进一步N抬至19.6°N附近, 经度Moving幅度减缓, 显示其在VietnamE部coastal 附近海域Moving速度有所放缓并最终消散. 整个过程中, Typhoon Harriet无Landfall记录, 始终在海上活动.

Intensity evolution and historical comparison

Harriet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初期仅为Tropical Depression, 气压1008hPa. Go to 7月后, 系统迅速整合, at 7月2日20时 intensified into Typhoon . 随后在S海海域经历爆发式增强, 特别是在7月4日20时至7月5日20时的24h内, Pressure从974hPa骤降至921hPa, max wind 飙升至60m/s, 达到Super Typhoon级别, 这也是其生命史中的巅峰状态. 然而, 巅峰状态维持Time较短, 7月6日08时起Intensity开始回落, 气压回升至933hPa, 并在随后48h内迅速 weakened into Tropical Depression, 最终 at 7月8日02时消散.

Compared with previous storms of the same name, the 1971 Harriet was significantly more intense than in other years. The 1974 Harriet peaked only as a severe tropical storm, with a pressure of 996hPa, while the 1965 Harriet reached severe typhoon status with a pressure of 977hPa. Even the 1967 Harriet, which also reached super typhoon status, had a minimum pressure of 953hPa, weaker than the 921hPa recorded by the 1971 Harriet. The data show that the 1971 Harriet was the strongest and had the lowest pressure among the listed typhoons of the same name, demonstrating tremendous explosive potential.
