1980 Typhoon Past typhoons named Betty Typhoon archive

[Quick Archive Overview]Typhoon Betty (No. 198021, a historical sequence number from before 1981) was a 1980 Northwest Pacific typhoon. It peaked as a super typhoon, with maximum winds of 60 m/s and a minimum central pressure of 925 hPa. It did not make landfall in China, was decommissioned on 1980-11-08, and had 47 track points throughout its lifetime.

Numbering note: International numbering for the Northwest Pacific has been assigned by the JMA in Japan, the designated regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1980. The number 198021 is a historical sequence number retained by the CMA. The numbers assigned that year by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological authorities may differ for the same typhoon and therefore cannot be compared directly.
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

Typhoon Betty Route Analysis

Track and Movement Characteristics

Typhoon Betty (198021) at 1980年10月28日08:00在Northwest Pacific低纬度海域 formed, 初始Position为6°N, 154°E. 其整体路径呈现显著的“W行后转 toward NE”的抛物线形态. 在生命史的前半段 (10月28日至11月4日) , 系统主要受引导气流影响 toward W, 横穿Philippines以E洋面. 期间经度从154°E迅速W移至122.8°E, 纬度由6°N缓慢N抬至15.8°N, 显示出稳定的W行分量.

At around 20:00 on November 4, Typhoon Betty reached its westernmost position at 15.8°N, 122.8°E, before making a clear turn. From November 5 onward, the system moved toward the northeast, with latitude rising rapidly and longitude gradually shifting east. By the time it dissipated at 20:00 on November 8, its center was at 29°N, 144°E. Throughout its lifetime, Betty never made landfall, remained over the sea, and eventually weakened into a tropical depression in the mid- to high-latitude ocean before dissipating.

Intensity evolution and historical comparison

Betty的Intensity演变经历了典型的“快速增强-巅峰维持-迅速减弱”过程. 从10月28日的Tropical Depression (10m/s, 1004hPa) 起步, 系统在 toward WMoving过程中急剧加强. 仅用约5天Time, at 11月4日02:00达到peak intensity, 此时中心最低气压降至925hPa, max wind 达60m/s, 评定为Super Typhoon. 值得注意的是, 在11月4日02:00至20:00期间, 其Intensity维持在巅峰状态 (60m/s, 925hPa) .

However, after turning toward the northeast, Betty's intensity rapidly declined as the surrounding environment changed. At 14:00 on November 5, its wind speed dropped abruptly to 35m/s and its central pressure rose to 980hPa, downgrading it from a super typhoon to a typhoon within a single day. It continued weakening afterward until dissipating.

Compared with previous typhoons of the same name, Betty's peak intensity in 1980, at 925hPa, fell between the 1972 typhoon at 910hPa and the 1987 typhoon at 891hPa, and was stronger than the 1975 typhoon at 948hPa and the 1984 typhoon at 980hPa. Although its minimum central pressure was not the strongest on record, its maximum winds of 60m/s indicated extremely high destructive potential, making it one of the stronger typhoons named Betty in history.

International numbering for the Northwest Pacific did not begin until 1981. Before then, individual agencies used their own numbering systems, so the numbers assigned by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological authorities may differ and cannot be compared directly.

Where does the track data for Typhoon Betty come from?
