Typhoon Jelawat (201217) 的生命史长达9天, 整体路径呈现典型的“NW行-N转-NE移”的抛物线形态. formed初期, 系统位 at Philippines以E洋面 (13.4°N, 131.6°E) , 受副热带高压引导稳定 toward NW. 在9月21日至26日期间, 其The latitude从13.4°N缓慢N抬至17.1°N, During由131.6°EW进至126.7°E, 显示出稳定的WNWMovingTrend.
Data show that on 28 September from 03:00 to 10:00, the Typhoon center length decreased slightly from 123.8°E to 124.1°E, then accelerated toward NE on 29 September, the length rapidly spread to 127°E and 132.2°E. This pathway twist indicates that the system was approaching the sea area of Japan S, guided by the W wind slopes, completed a significant twist toward of the migration from NW to NE, eventually at 30 September Landfall Japan and Songhua County.
The Typhoon underwent a dramatic enhancement and maintenance process. Starting from the 21st of September's Tropical Storm (18m/s, 1000hPa), the explosive enhancement to Super Typhoon took only about 3 days. On 24th of September at 08:00, its wind speed reached 62m/s, the air pressure dropped to 915hPa; and on 26th of September at 02:00 reached the peak of °E, max wind 65m/s, minimum pressure 905hPa. It is worth noting that Jelawatined an extremely long Time at the Super Typhoon level (wind speed ≥51m/s), from 24th of September to 28th of September at 17:00,ining a continuous 5 days of high Intensity operation, even with a slight weakening in the latter period, until 29th of September's
Jelawat peaked only at Tropical Storm (1000hPa) in 2023, and Jelawat reached Super Typhoon level in 2018, but the lowest air pressure was 935hPa, weak at 905hPa in 2012.
