Characteristics of Typhoon Freda
Track and Turning Characteristics
Typhoon Freda (198713) 的生命史长达14天余, 整体路径呈现典型的“NW行进—近海转 toward —NE远去”的抛物线形态. formed初期, 系统自13°N, 144°E附近 toward NW, at 9月6日至9日期间维持稳定的WNW路径, 纬度从14.8°N缓慢N抬至16.6°N, 经度则显著W进至139.1°E. 9月10日, Typhoon 到达最W端Position (137.3°E) , 此时也是其路径的关键转折点. 随后, 受大气环流引导气流改变影响, typhoon track发生明显逆时针转 toward , 开始 toward NE direction加速Moving. 9月12日后, 系统彻底脱离低纬海域, 沿Japan以E海域N上, 最终 at 9月19日消散 at 47°N, 163°E的高纬度洋面. 全生命周期无Landfall记录, 主要活动区域集中在开阔洋面.
Intensity evolution and historical comparison
该Typhoon 经历了完整的生命循环, intensity 变化剧烈且峰值极高. 从9月5日的Tropical Depression (12m/s, 1004hPa) 起步, 系统在短短5天内迅速增强, at 9月10日达到巅峰状态, 中心最低气压降至915hPa, max wind 高达65m/s, 定性为Super Typhoon. 巅峰期维持Time较短, 9月11日起Intensity开始波动减弱, 气压回升至930hPa. Go to 转 toward 阶段后, 随着纬度升高和海温降低, Typhoon 持续减弱, 9月15日降级为Severe Tropical Storm, 最终在N上过程中逐渐转化为温带气旋性质并消散.
Compared with previous storms of the same name, Freda in 1987 was markedly more intense. The peak intensities of Freda in 1984, 1977, and 1971 were only severe tropical storms or ordinary typhoons, with minimum central pressures above 978 hPa. Only Freda in 1965 had reached super typhoon status, with a central pressure of 923 hPa, but Freda in 1987 recorded an even lower minimum pressure of 915 hPa, showing that this named series occasionally produces extremely intense severe typhoons.
