Typhoon Judy, international code 197428, international name JUDY, 1974 Northwest Pacific typhoon. Formed: 1974-12-17 00:00:00, ended: 1974-12-19 06:00:00. Peak intensity: Tropical Storm, minimum central pressure: 1000 hPa, max wind: 20m/s.
Typhoon Judy at 1974-12-17 00:00:00 at 14°N, 116.1°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Tropical Storm intensity with max winds of 20 m/s (~72 km/h) and a minimum central pressure of 1000hPa, recorded at 1974-12-18 12:00:00.
1974-12-19 06:00:00 After, Typhoon Judy gradually weakened and was numbered off on 1974-12-19 06:00:00 was numbered off; its lifecycle recorded 10 track points.
Typhoon Judy (197428)'s life history is short, the main activity area is at S Sea W area. From the observation data of 17 December 1974 00:00 to 19 December 06:00, the system as a whole presents a stable WSWTrend. Initial Position position at lat 14.0°N, 116.1° near, then continues toward WS direction advance. Thro the life cycle, the latitude is gradually reduced from 14.0°N to 12.0°N, the length is moved from 116.1°EW to 109.5°E, the horizontal transition range is about 6.6 longitude units and 2 latitude units.
During December 17 to 18, the systemined a more linear Moving path, until December 19 06:00 before the dispersal, its Center had been close to the coastal waters of VietnamE (lng 109.5°) , but according to records confirmed no Landfall behavior.
In terms of Intensity changes, Typhoon Judy experienced the process of 'formed-weak enhancement-fast weakening'. on December 17, 00:00, the system intensity reached its peak, upgraded to Tropical Storm, the max wind increased to 20m/s. However, this high intensity stateined only about 12h, since December 19, 00:00, the wind speed fell back to 15m/s, downgraded to Nameless, and at 6h further weakened to 10m/s, marking the system's disappearance.
JudyIntensity in 1974, compared to the previous typhoon, was significantly weaker. data showed that the 1979s, 1982s, 1986s and 1989s of the same name typhoon peak intensity reached Severe Typhoon or Super Typhoon level, while Judy in 1974 only for Tropical Storm scale, max wind 20m/s far lower at other years of the same name destructive intensity.
