Typhoon Ogden, international code 198109, international name OGDEN, 1981 Northwest Pacific typhoon. Formed: 1981-07-27 00:00:00, ended: 1981-08-01 00:00:00. Peak intensity: Typhoon , minimum central pressure: 975 hPa, max wind: 33m/s.
Typhoon Ogden at 1981-07-27 00:00:00 at 22.5°N, 150°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 33 m/s (~119 km/h) and a minimum central pressure of 975hPa, recorded at 1981-07-30 12:00:00.
Typhoon Ogden gradually weakened and was numbered off on 1981-08-01 00:00:00 was numbered off; its lifecycle recorded 21 track points.
Typhoon Ogden (198109) 的生命周期始 at Northwest Pacific远洋海域, 整体路径呈现稳定的NW toward Moving特征. formed初期 (7月27日) , 系统位 at 150°E附近, 随后持续 toward NW direction推进. 从经The latitude坐标序列分析, 该Typhoon 在Moving过程中未出现明显的路径转折或停滞现象, 其During从150°E稳步W移至125.8°E, 纬度则从22.5°NN抬至36°N, 横跨了约14个纬距和24个经距. 这种长距离, 单 toward 性的Moving轨迹表明, 该系统主要受副热带高压S侧E气流引导, 且引导气流相对稳定. 值得注意的是, 尽管路径指 toward 朝鲜半岛及Japan以S海域, 但根据观测记录, 该Typhoon 全程无Landfall记录, 最终在较高纬度海域减弱消散.
Ogden的Intensity演变经历了典型的“ formed-增强-巅峰-减弱”过程. 7月27日至28日中午, 系统维持Nameless至Tropical Storm等级, wind speed从12m/s缓慢增至23m/s. 7月28日12时至29日期间, intensity 迅速提升为Severe Tropical Storm, wind speed稳定在25-28m/s区间, 并维持较长Time. 7月30日12时, 系统在31.2°N, 132.7°E附近达到生命史中的peak intensity, max wind 录得33m/s, 定性为Typhoon 级. 然而, 巅峰状态极为短暂, 仅维持6h后, at 30日18时即 weakened into Severe Tropical Storm (28m/s) . Go to 7月31日后, 随着The latitude进一步N抬至33°N以N, 系统结构迅速瓦解, wind speed由20m/s骤降至12m/s, 最终 at 8月1日00时在36°N附近 weakened into Nameless并结束code. 整个增强期历时约3天, 而减弱过程相对迅速, 显示出中高纬度环境对其Intensity的显著抑制作用.
As the 9th Typhoon in 1981, Ogden's peak intensity is Typhoon level (33m/s) , belonging to the at medium intensity tropical cyclone. Compared with other systems that could reach a stronger level (such as Severe Typhoon or Super Typhoon) in the same year, Ogden's Max Wind did not break the threshold of 40m/s, and the minimum pressure data was missing, can not make an accurate contrast of the atmospheric dimension.
