2017-10-23 08:00:00 After, Typhoon Lan gradually weakened and was numbered off on 2017-10-23 08:00:00 was numbered off; its lifecycle recorded 51 track points.
Typhoon Lan (201721) 的生命史始 at Northwest Pacific低The latitude海域, 整体路径呈现典型的“抛物线”型Moving特征. formed初期 (10月16日至17日) , 系统位 at lat 9.7°至10.9°N, 132.3°至136.2°之间, 主要受引导气流影响 toward W direction缓慢Moving, 纬度变化幅度较小. 10月18日后, 路径逐渐转为NW direction, During稳定在lng 130°至132°区间, 纬度开始显著N抬.
The key switch toward node appeared between October 20 and 21. Data showed that October 20 at 05:00 to 17:00, the Typhoon center lengthined near 130°E, then at 21 at 05:00 toward E deviated to 130.9°E, marking the system completed the switch from NW to NE toward . After that, the Typhoon accelerated toward NE, the latitude rapidly climbed from 21.1°N to 23°N to 37°N, the length stretched to 141.1°E, eventually on the island of Japan to E ocean transformed into a temperature or dispersal cycle. Landfall records show that the system at October 23 at 02:00 at Typhoon Intensity (40m/s, 955hPafall) Land Japan is at the end of life at the high-speed N phase.
The initial phase was Tropical Storm (18-20m/s), intensified into Severe Tropical Storm 18 October, upgraded to Typhoon 19 October 20 to 21 October is its main eruption period, Pressure dropped sharply from 960hPa to the lowest 925hPa, max wind jumped to 58m/s, to the Super Typhoon level.
Compared with the same name Typhoon, the 7th Typhoon Lan in 2023 also reached the Super Typhoon level, with a minimum pressure of 930hPa. In comparison, the 2017 Lan's minimum air pressure was lower (925hPa vs 930hPa), the peak wind speed was higher (58m/s vs not providing a specific wind speed but the air pressure was slightly high suggesting that the intensity was equal to or slightly weaker), indicating that the 2017 Lan's peak intensity was slightly overtaken at the same name at 2023 Typhoon .
