Analysis of Typhoon IVY's track characteristics
Path and Moving Characteristics
Typhoon Georgia (196219) maintained a steady, continuous NNW-moving trend during the observation period. Based on 7 track points from 06:00 on October 28 to 18:00 on October 29, 1962, its center moved from 16.7°N, 137.7°E to 22.3°N, 138.9°E. Longitude changed only slightly, shifting about 1.2° east, while latitude advanced about 5.6° north, indicating a predominantly north-northeastward movement. The smooth track showed no significant turns or stagnation, suggesting stable and uncomplicated steering flow. All observation points were over open waters, with no landfall recorded, so the typhoon remained at sea throughout and caused no direct impacts on land.
Intensity Evolution Analysis
Georgia maintained extremely high intensity early in the observation period. From 06:00 to 18:00 on October 28, its maximum wind remained at 51 m/s, classified as a super typhoon, indicating a solid core structure. Beginning at 00:00 on October 29, however, its intensity declined sharply and rapidly. Over the next 18 hours, maximum wind fell from 41 m/s as a typhoon to 30 m/s as a severe tropical storm, then 20 m/s as a tropical storm, and finally weakened into a tropical depression with winds of 17 m/s by 18:00 on October 29. This abrupt weakening across four intensity categories in a short period usually indicates major changes in environmental conditions, such as increased vertical wind shear or lower sea surface temperatures, which disrupted its energy supply.
Same-Name Comparison
Compared with previous typhoons bearing the same name, Georgia in 1962 exhibited a significant intensity advantage. While Georgia in 2004 peaked only as a tropical storm with a minimum pressure of 990 hPa, and Georgias in 1986 and 1983 peaked as severe tropical storms, the 1962 typhoon had already reached super typhoon status with winds of 51 m/s at the start of the observation period. Georgia in 1989 also reached super typhoon status, but the 1962 storm maintained a high-intensity state throughout its brief recorded lifecycle. Overall, Georgia in 1962 was among the most intense storms with this name in the historical record, with a peak intensity far exceeding that of most same-name systems.

FAQ
What number typhoon of 1962 was Typhoon IVY?
196219 is the historical number used by the CMA for Typhoon IVY (the 19th typhoon of 1962); international name: IVY. The international unified code system for the Northwest Pacific began in 1981. Before then, each agency used its own numbering system, including the JMA (Japan), the Joint Typhoon Warning Center (USA), and China’s meteorological authorities, so the numbers assigned to the same typhoon may differ and cannot be directly compared.
Where does the track data for Typhoon IVY come from?
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.
What was the maximum intensity of Typhoon IVY?
Typhoon IVY peak intensity is Typhoon , max wind 40m/s, minimum central pressure 990 hPa.
Did Typhoon IVY make landfall?
According to the records, Typhoon IVY did not make landfall along China’s coast.
Where can I view typhoon IVY's live track map?
