Typhoon Chebi, international code 201821, international name JEBI, 2018年Northwest PacificTyphoon . formedTime: 2018-08-28 08:00:00, 结束Time: 2018-09-05 05:00:00. peak intensity: Super Typhoon, 最低Pressure: 905 hPa, max wind : 65m/s.
Typhoon Chebi at 2018-08-28 08:00:00 at 15.4°, lng 157° over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Super Typhoon intensity with max winds of 65 m/s (~234 km/h) and a minimum central pressure of 905hPa, recorded at 2018-08-31 14:00:00.
2018-09-04 12:00:00, Typhoon Chebi landfall in Japan's Quartet Island County.
2018-09-05 05:00:00 After, Typhoon Chebi gradually weakened and was numbered off on 2018-09-05 05:00:00 was numbered off; its lifecycle recorded 48 track points.
Typhoon Chebi (201821) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“W行—NW行—N转”抛物线形态. formed初期 (8月28日至30日) , 系统稳定 toward WMoving, The latitude从15.4°N缓慢N抬至17.6°N, During由157°E快速W进至149.2°E, 显示其受副热带高压S侧E气流引导显著. 8月31日至9月1日, 随着系统接近Japan以S洋面, 路径逐渐转为NW direction, 纬度迅速提升至19.6°N.
关键的转 toward 点出现在9月2日至3日期间. 数据显示, 9月2日02:00位 at 21.7°N, 136.5°E, 至9月4日02:00移至30.2°N, 132.9°E, 这一阶段During变化极小甚至略有W折后迅速E扩, 表明系统在遭遇W风带槽前气流时发生了明显的 toward N转 toward . 9月4日中午LandfallJapan四国岛德岛 County后, 路径加速 toward NE direction延伸, 最终 at 9月5日05:00到达44.9°N高The latitude地区并减弱消散. 整个Moving过程连贯, 无明显停滞或打转现象.
Chebi经历了极为迅猛的增强过程. 从8月28日的Tropical Storm (18m/s, 1002hPa) 起步, 仅用约3天Time, at 8月31日17:00达到peak intensity, 中心最低气压降至905hPa°E, max wind 高达65m/s, 确立为Super Typhoon等级. 这种在短Time内气压骤降近100hPa的爆发式增强, 体现了极佳的热力条件支持. 巅峰状态维持约24h后, 自9月2日起开始缓慢减弱, 但直至9月4日Landfall前, 仍保持Severe Typhoon级别 (45m/s, 945hPa) , 显示出极强的结构完整性.
Chebi’s 2018 Intensity has a overwhelming advantage over previously named Typhoon. 2024 Chebi (202417) and 2013 Chebi (201309) peak only for Severe Tropical Storm, minimum pressure of respectively 985hPa and 980hPa, far weaker at 2018 individual. even compared to Super Typhoon’s 2001 Chebi (200102) 2018 Chebi’s minimum air pressure (905hPa vs 944hPa) is lower ° E, max wind is higher, is the most destructive process in the name sequence in recent years.
