Typhoon Lex, international code 198628, international name LEX, 1986 Northwest Pacific typhoon. Formed: 1986-12-03 18:00:00, ended: 1986-12-09 06:00:00. Peak intensity: Tropical Storm, minimum central pressure: 994 hPa, max wind: 20m/s.
Typhoon Lex at 1986-12-03 18:00:00 at 8.1°N, 163°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 1986-12-04 06:00:00.
1986-12-09 06:00:00 After, Typhoon Lex gradually weakened and was numbered off on 1986-12-09 06:00:00 was numbered off; its lifecycle recorded 23 track points.
Typhoon Lex (198628) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的“NW-N-NE”抛物线型转 toward 特征. formed初期 (12月3日至4日) , 系统位 at 低The latitude海域 (约8°N, 163°E附近) , 受引导气流影响, 主要 toward NW. 在12月4日06:00达到最W端During161.3°E后, Moving direction逐渐转为N.
Go to 12月5日至7日阶段, Typhoon 持续 toward N推进, The latitude从10.2°N迅速攀升至17.5°N, During则从157.5°EW移至142.4°E, 显示出明显的N toward 加速Trend. 值得注意的是, 12月7日12:00左右, 系统在17.5°N, 142.4°E附近完成关键转 toward , 随后路径折 toward NE. 12月8日至9日消散前, Typhoon 沿NE direction快速Moving toward 中高纬度开阔洋面, 最终 at 12月9日06:00在25.8°N, 149.6°E处结束观测. 全生命周期内无Landfall记录, 始终在海上活动.
从Intensity变化来看, Lex属 at 典型的弱热带气旋. 其在 formed后短Time内迅速增强, at 12月4日06:00达到peak intensity, 定性为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 (12月4日18:00) 即 weakened into Nameless, wind speed降至17m/s. 此后直至消散, 系统长期维持在Nameless等级, wind speed在12m/s至15m/s之间波动, 未再出现显著增强过程, 表明其内部结构松散或环境条件不利 at 进一步发展.
The data show that the 1983 Lex (198316) and the 1980 Lex (198010) peak intensity both reached the typhoon level, while the 1986 Lex only for the Tropical Storm scale. This intensity difference reflects the same year Typhoon in the different years' climate background and formed environment, its development potential there is a huge gap.
