Analysis of Typhoon Vera
Track and Movement Characteristics
The lifecycle of the fifth typhoon of 1977, Vera, began over the northwestern Pacific. Its overall track displayed a pronounced westward trend, with no significant northward turn or landfall. During the initial stage from July 25 to 27, the system was located over waters east of longitude 130°E, with its latitude fluctuating slightly between 24.5°N and 25.8°N. It moved relatively slowly, mainly adjusting toward the west-southwest. After July 28, as its intensity increased, its westward component became much more pronounced. Its longitude advanced rapidly from 130.7°E to 121.5°E, spanning the broad sea area east of the Philippines.
Notably, as the typhoon passed near the Bashi Channel from July 30 to 31, its track showed a slight northward uptick, with its latitude rising from 23.3°N to 24.9°N. It then continued steadily westward through the northern part of the South China Sea. Until the end of its lifecycle on August 1 to 3, the system maintained a westward course toward the coastal waters and inland fringe of southern China. It finally dissipated near 107.5°E, 26°N at 14:00 on August 3. All 36 track points show a smooth trajectory with no dramatic directional shifts, making it a typical westward-moving typhoon track.
Intensity evolution and historical comparison
“Vera”经历了完整的生命周期, intensity 变化剧烈且峰值极高. formed初期为Tropical Depression (1008hPa) , 经过约3天的缓慢增强, at 7月28日晚升级为Severe Tropical Storm. 随后Go to 快速增强期, 仅用不到30h, Pressure从986hPa骤降至928hPa, max wind 飙升至50m/s, at 7月30日08时达到Severe Typhoon级别. 7月31日02时, 虽气压微升至930hPa, 但结合巅峰数据 (最低气压925hPa, max wind 55m/s) 判断, 该系统在此期间达到了Super TyphoonIntensity, 并在高Intensity状态维持了约24h.
Beginning August 1, Typhoon Vera rapidly weakened due to environmental factors. Its central pressure rose to 980 hPa within 30 hours, and it was downgraded to a severe tropical storm before ultimately degenerating into a tropical depression. Compared with other storms of the same name, Vera in 1977 was highly representative in intensity. Its peak central pressure of 925 hPa was higher than those of Vera in 1989 (980 hPa) and 1983 (967 hPa), and slightly higher than Vera in 1986 (923 hPa), but lower than Vera in 1979 (915 hPa). This indicates that the 1977 system belonged to the high-intensity category of super typhoons. Its explosive development was comparable to the same-named typhoons in 1979 and 1986, and far exceeded that of comparable systems in other years.

FAQ
Typhoon Vera is the 1977 Typhoon.
197705 is the historical number retained by the CMA for Typhoon Vera (the fifth typhoon of 1977); its international name was VERA. International numbering for Northwest Pacific typhoons did not begin until 1981. Before then, each agency used its own numbering system, so the numbers assigned by JMA (Japan), the USA Joint Typhoon Warning Center, and China’s meteorological agencies may differ for the same typhoon and cannot be directly compared.
Where does the track data for Typhoon Vera 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 Vera?
Typhoon Vera peak intensity is Super Typhoon, max wind 55m/s, minimum central pressure 925 hPa.
Is the Typhoon VeraLandfall?
According to records, the Typhoon Vera is not in our coastal landfall.
Where can I view typhoon Vera's live track map?
