1978 Typhoon Past typhoons named Ora Typhoon archive

[Quick Archive Overview]Typhoon Ora (No.197821, the historical number used before 1981) was a 1978 Northwest Pacific typhoon. It peaked as a severe typhoon, with maximum winds of 45m/s and a minimum central pressure of 943hPa. It did not make landfall in China, was numbered off on 1978-10-16, and has 27 recorded track points.

Numbering note: The internationally standardized numbering system for the Northwest Pacific has been assigned by the JMA (Japan), the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1978. The identifier 197821 is the historical number retained by the CMA. The identifiers used that year by the JMA (Japan), the Joint Typhoon Warning Center (USA), and China’s meteorological authorities for the same typhoon may differ and cannot be compared directly.

Track and Turning Characteristics

Typhoon Ora (197821) at 1978年10月10日02时在Northwest Pacific洋面 formed, 初始Position为16.8°N, 134.6°E. 在生命史初期, 该系统呈现稳定的NW toward MovingTrend, 从 formed至10月13日14时, 纬度由16.8°NN抬至23.9°N, 经度由134.6°EW进至122.5°E, 整体Move toward WNW. 值得注意的是, 10月13日14时前后, Typhoon 中心到达最W端 (122.5°E) , 随后路径发生显著转折. 自10月14日02时起, 系统转为NE, 经度迅速E退, 从123.1°E移至10月16日14时的145°E. 整个生命周期内, Typhoon 未Landfall任何land, 始终在海上活动, 最终 at 10月16日14时在34.3°N, 145°E附近减弱消散. 这种先NW行后转 toward NE的“抛物线”型路径, 符合该季节副热带高压边缘引导气流变化的典型特征.

Intensity evolution and historical comparison

In terms of intensity, Ora rapidly intensified to its peak and then weakened quickly. Starting as a tropical depression on October 10 with winds of 15m/s and a central pressure of 1000hPa, the system intensified into a severe tropical storm within 48h and became a typhoon at 14:00 on October 12. At 14:00 on October 13, it reached peak intensity, with a minimum central pressure of 943hPa and maximum winds of 45m/s, qualifying it as a severe typhoon. However, it maintained peak intensity for a very short time. Just 12h later, at 02:00 on October 14, its central pressure had risen to 970hPa and its wind speed had dropped sharply to 35m/s, indicating rapid weakening caused by the changing environmental field. The system continued to decay afterward, moving into the mid- to high-latitude seas as a tropical storm.

Compared with previous typhoons of the same name, the 1978 Ora was significantly stronger than its counterparts in 1975, 1972, and 1966, with peak central pressures of 970hPa, 981hPa, and 970hPa, respectively. It was slightly weaker than the 1968 super typhoon Ora, which had a central pressure of 932hPa. Although the 1978 Ora did not set the historical record for the strongest storm with this name, it was among the more intense storms of the past decade, and its rapid intensification was noteworthy.
