1980 Typhoon Past typhoons named Dinah Typhoon archive

[Quick Archive Overview]Typhoon Dinah (No. 198022, the pre-1981 numbering system) was a 1980 Northwest Pacific typhoon. It peaked as a severe typhoon, with maximum winds of 50 m/s and a minimum central pressure of 941 hPa. It did not make landfall in China and was designated as dissipated on 1980-11-26. Twenty-three track points were recorded throughout its lifecycle.

Numbering note: International numbering in the Northwest Pacific has been assigned by the JMA in Japan, the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1980, and 198022 is the historical number retained by the CMA. The JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities may have assigned different numbers to the same typhoon that year, so the identifiers cannot be compared directly.

Typhoon Dinah Route Characteristics

Track and Movement Characteristics

Typhoon Dinah (198022) formed at Northwest Pacific低纬度海域, 初始Position位 at 6°N, 165.6°E. 在生命史初期, 系统呈现稳定的NW toward MovingTrend. 从11月20日14时至11月23日08时, Typhoon 中心纬度由6°NN抬至16.2°N, 经度由165.6°EW移至144.7°E, 整体路径指 toward WNW direction. 值得注意的是, 在11月23日08时达到peak intensity后, Moving direction发生显著转折. 自11月23日14时起, 经度数值开始回升 (从144.1°E逐渐 toward E增加) , 表明Typhoon 在17.2°N附近完成转 toward , 随后路径转为NE direction. 至11月26日02时消散前, Center已达32°N, 170°E. 整个生命周期中, Typhoon 未Landfall任何land, 始终在洋面上活动, 路径形态呈现典型的“抛物线”型转 toward 特征, 转 toward 点位 at lat 17度左右的中低纬度海区.

Intensity evolution and historical comparison

该Typhoon 经历了快速增强, 巅峰维持及缓慢减弱三个阶段. 初生时为Tropical Depression (12m/s) , 在约36h内迅速 intensified into Severe Tropical Storm, 并 at 11月22日08时升级为Typhoon (35m/s) . 随后Intensity继续攀升, 在11月23日08时达到巅峰, 此时中心最低气压降至941hPa, max wind 达50m/s, 评定为Severe Typhoon等级. 巅峰状态维持Time较短, 约6h后wind speed略降至45m/s, 但直至11月24日02时才降级为Typhoon . 此后在 toward NEMoving过程中, 受高纬度环境影响, intensity 呈阶梯式减弱, 最终消散时恢复为Tropical Storm级别 (20m/s) .

Compared with previous typhoons of the same name, Dinah in 1980 had above-average intensity. Its peak central pressure of 941 hPa was lower than those of Dinah in 1977 at 963 hPa, 1974 at 974 hPa, and 1971 at 965 hPa, indicating a stronger pressure gradient near the core. However, it was less intense than Dinah in 1987, which reached super typhoon status with a minimum central pressure of 920 hPa. Overall, Dinah in 1980 was a typical severe typhoon over the open ocean, characterized by rapid intensification and a clearly defined transition in its track.

FAQ

Typhoon Dinah was the 1980s Typhoon.

The identifier 198022 for Typhoon Dinah is the historical number retained by the CMA, representing the 22nd typhoon of 1980, while its international name was DINAH. International numbering in the Northwest Pacific did not begin until 1981; before then, each agency assigned its own numbers. The JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities may have assigned different numbers to the same typhoon, so the identifiers cannot be compared directly.

Where does the track data for Typhoon Dinah come from?

Path. Data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speed refers to 2-min sustained wind speed.
