Typhoon Vernon, international code 198401, international name VERNON, 1984 Northwest Pacific typhoon. Formed: 1984-06-07 18:00:00, ended: 1984-06-11 00:00:00. Peak intensity: Tropical Storm, minimum central pressure: 994 hPa, max wind: 20m/s.
Typhoon Vernon at 1984-06-07 18:00:00 at 11.9°N, 114.8°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 994hPa, recorded at 1984-06-09 12:00:00.
Typhoon Vernon gradually weakened and was numbered off on 1984-06-11 00:00:00 was numbered off; its lifecycle recorded 14 track points.
In 1984, the 1st Typhoon “Vernon” had a short history of life, from formed to dispersed for about 3 and a half days. Its initial position at S Sea Central waters (11.9°N, 114.8°E) , the overall Moving path showed a stable NW toward Trend. During the period from June 7th, 18th to June 9th, 12, the system’s central latitude rose from 11.9°NN to 14.9°N, the length moved from 114.8°EW to 111.9°E, indicating its influenced guided airflow, continuing toward NW. It is noteworthy that the Typhoon course did not occur a noticeable path toward or stagnant phenomenon, the Moving trajectory being a more straight line.
“Vernon”的Intensity变化经历了“缓慢增强—短暂巅峰—迅速减弱”的过程. formed初期为Nameless, max wind 维持在10-12m/s. 6月8日18时起, wind speed增至15m/s, 随后在6月9日06时达到17m/s. at 6月9日12时, 系统Intensity达到巅峰, 升级为Tropical Storm, max wind 录得20m/s. 然而, 这一巅峰状态维持Time极短, 仅约6h后, 即6月10日00时, 系统便重新降级为Nameless, wind speed回落至17m/s. 此后, intensity 呈阶梯式下降, 从17m/s逐步降至15m/s, 最终在消散前降至12m/s. 数据显示, 该系统结构可能较为松散, 难以在不利环境下维持高Intensity, 导致其快速衰减.
In 1984, the 'Vernon' peak was only Tropical Storm (20m/s), while in 1993, 1987 and 1990 the same-name typhoon peak intensity reached typhoon or severe typhoon level, and in 1980 'Vernon' reached Super Typhoon level.
