1977 Typhoon Past typhoons named Lucy Typhoon archive

[Quick Archive Overview]Typhoon Lucy (No.197717, its historical number before 1981) was a 1977 Northwest Pacific typhoon. It peaked as a super typhoon, with maximum winds of 60m/s and a minimum central pressure of 917hPa. It did not make landfall in China and was numbered off on December 9, 1977, with 52 track points recorded throughout its life cycle.

Numbering note: The unified international numbering system for the Northwest Pacific has been operated by the JMA in Japan, the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1977. The designation 197717 is the historical identifier retained by the CMA, while the numbers assigned that year by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological authorities could 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.

Intensity evolution and historical comparison

Lucy's intensity underwent explosive intensification followed by a gradual weakening. It strengthened from a tropical storm on December 1 (20m/s, 995hPa) to a super typhoon on December 3 (55m/s, 925hPa) in just 48 hours, with the pressure dropping 70hPa and wind speed increasing by 35m/s, indicating extremely rapid intensification. The storm remained at its peak from December 3 to 4, reaching a minimum pressure of 917hPa and maximum wind speed of 60m/s, confirming its super typhoon status. After turning toward the northeast, it weakened rapidly under the influence of the high-latitude environment and wind shear, degenerating into a severe tropical storm by December 6.

Compared with previous typhoons of the same name, Lucy in 1977 reached a relatively high intensity. Its minimum pressure of 917hPa was lower than those of Lucy in 1974 (990hPa), 1968 (941hPa), and 1965 (944hPa), indicating a more compact and powerful core. However, its peak intensity was slightly below that of Lucy in 1971, which reached a minimum pressure of 912hPa. Overall, it ranks among the more intense storms in the history of the name Lucy and demonstrates that the remote Northwest Pacific can still support highly intense tropical cyclones in late autumn.

FAQ

Lucy is the 1977 Typhoon.

The designation 197717 is the historical identifier retained by the CMA for Typhoon Lucy, meaning the 17th tropical cyclone of 1977, with the international name LUCY. The unified international numbering system for the Northwest Pacific was not introduced until 1981. Before then, individual agencies maintained their own numbering systems, and the numbers assigned by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China's meteorological authorities could differ for the same typhoon and therefore cannot be compared directly.

Where does the track data for Typhoon Lucy come from?

Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

What is the highest level of Typhoon Lucy?

Typhoon Lucy peak intensity is Super Typhoon, max wind 60m/s, minimum central pressure 917 hPa.

Typhoon Lucy Landfall?

According to records, Typhoon Lucy is not in our coastal Landfall.

Where can I view typhoon Lucy's live track map?
