Analysis of Typhoon Owen's Track Characteristics
Track and Turning Characteristics
Typhoon Owen (197915) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行—N转—NE移”的抛物线形态. formed初期 (9月23日) , 系统在12.2°N附近形成Tropical Depression后, 稳定 toward NW, 穿越Philippines以E洋面. 随着纬度升高至21°N左右, 系统逐渐逼近副热带高压W脊线边缘, Moving速度放缓并出现路径转折迹象.
A critical turning point occurred from September 26 to 27. The typhoon’s center was located near 22.8°N–23.9°N, 129°E. After reaching peak intensity, it was steered by the airflow ahead of a westerly trough, shifting from a northwestward course to due north before quickly turning northeast. After September 30, the system accelerated northeastward across waters east of Japan and finally weakened and dissipated near 46.7°N, 174°E on October 3. It made no landfall during its lifetime and was mainly active over open waters.
Intensity evolution and historical comparison
Owen的Intensity演变经历了快速增强, 巅峰维持及缓慢减弱三个阶段. 从9月23日的Tropical Depression (15m/s, 1000hPa) 到9月25日发展为Typhoon (35m/s, 965hPa) , 系统在48h内wind speed增加20m/s, 气压下降35hPa, 显示出强烈的爆发性增强特征. 9月26日20时, Typhoon 达到peak intensity, max wind 50m/s, minimum pressure 918hPa, 定性为Severe Typhoon. 此后, 随着纬度进一步升高及海水Temperature降低, 系统核心对流减弱, 气压回升至945hPa以上, 但直至10月1日Go to 高纬度地区前, 仍维持Typhoon 级Intensity (35m/s) .
Compared with other storms of the same name, Owen in 1979 was significantly more intense than most historical systems. Its minimum pressure of 918 hPa was lower than those of Owen in 1994 (980 hPa), 1989 (960 hPa), and 1986 (987 hPa). Although Owen reached super typhoon status in 1990 with a pressure of 930 hPa, the exceptionally low pressure of 918 hPa in 1979 indicated a deeper warm-core structure and greater destructive potential, making it a notable severe typhoon in the sequence of storms named Owen.

FAQ
Which number typhoon was Typhoon Owen in 1979?
Owen's number 197915 is the historical identifier retained by the CMA, corresponding to the 15th typhoon of 1979. Its international name was OWEN. The unified international numbering system for the Northwest Pacific did not begin until 1981. Before then, the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological agencies each used their own numbering systems, which may differ for the same typhoon and therefore cannot be compared directly.
Where does Typhoon Owen's track data come from?
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.
What was the peak intensity level of Typhoon Owen?
Typhoon Owen peak intensity is Severe Typhoon, max wind 50m/s, minimum central pressure 918 hPa.
Did Typhoon Owen make landfall?
According to records, Typhoon Owen did not make landfall on China's coast.
