Typhoon Joan, international code 196427, international name JOAN, 1964 Northwest Pacific typhoon. Formed: 1964-11-06 12:00:00, ended: 1964-11-09 12:00:00. Peak intensity: Typhoon , minimum central pressure: 1000 hPa, max wind: 35m/s.
Typhoon Joan at 1964-11-06 12:00:00 at 13.1°N, 117.5°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Typhoon intensity with max winds of 35 m/s (~126 km/h) and a minimum central pressure of 1000hPa, recorded at 1964-11-08 12:00:00.
1964-11-09 12:00:00 After, Typhoon Joan gradually weakened and was numbered off on 1964-11-09 12:00:00 was numbered off; its lifecycle recorded 13 track points.
Typhoon Joan (196427) has a short history of life, formed from 12 a.m. on 6 November 1964 to dispersed at 12 a.m. on 9 November, with a duration of approximately 3 days. From the route sampling data, the Typhoon overall showed a stable W-line trend, with a smaller latitude variation, the main activity range concentrated at 12.7° to 14.5° between.
It is worth noting that between 00:00 on November 8th and 00:00 on November 9th, as the system penetrates into the Sea W, its length rapidly moves from 111.8°E to 108°E, Moving speed accelerates. In the end of life, the system center toward N deviates to 14.5°N, while continuing toward WMoving to 105.5°E, eventually weakening dispersal in the ocean by E. No landfall records throughout the cycle, alwaysining the state of maritime activity.
Joan的Intensity演变呈现出典型的“缓慢增强, 快速达到巅峰, 迅速减弱”特征. formed初期至11月7日中午, 系统长期维持Tropical Storm等级, max wind 稳定在20m/s. 11月7日18时起, wind speed增至23m/s, 随后在11月8日00时 intensified into Severe Tropical Storm (28m/s) . 仅6h后, 即11月8日06时, 系统进一步升级为Typhoon , max wind 达33m/s, 并 at 同日12时达到peak intensity, max wind 为35m/s.
Time was extremely short, after just 6h (November 8, 18h) it rapidly weakened into Severe Tropical Storm (28m/s), then continued to decline, until November 9, 12th it was reduced to Nameless (12m/s).
Compared to the previous typhoon, Joan's intensity in 1964 was at a medium downward level. compared to the 1997 Joan (Super Typhoon) and the 1970 Joan (Super Typhoon), its peak intensity was significantly weaker; compared to the 1962 Joan (Typhoon), the intensity grade was the same but the upper speed was slightly lower; strong only at the 1973 Joan (Tropical Storm).
