Typhoon Jelawat trajectory
Path evolution and turn toward characteristics
Typhoon Jelawat (201217) 的生命史长达11天, 整体路径呈现典型的“NW行—转 toward NE”的抛物线形态. formed初期, 系统位 at Philippines以E洋面 (135.9°E) , 随后 toward W, 至9月22日抵达130°E附近. 此后, 受副热带高压引导, Typhoon 主体稳定 toward NW direction推进, 逐渐逼近我国Taiwan以E海域. 在9月28日前后, 路径出现关键转折, Typhoon 中心从lat 24.4°N, 125.3°附近开始明显转 toward NE, 加速穿越琉球群岛S部海域, 并最终 at 9月30日15:00在Japan和歌山 CountyLandfall. Landfall后, 系统继续 toward NE direction深入, 迅速Go to 高纬度海域, 最终 at 10月1日在North AtlanticW部 (43.8°N, 149.2°E) weakened into Tropical Storm并结束监测. 整个过程中, track points分布密集, 显示其Moving速度在转 toward 后显著加快.
Intensity evolution and historical comparison
This Typhoon underwent dramatic intensity changes and followed a typical rapid intensification, peak maintenance, and gradual weakening pattern. It began as a Tropical Depression on September 20 (15m/s, 1008hPa) and developed into a Super Typhoon by September 24 in just 4 days (55m/s, 935hPa). It reached its lifetime peak on September 26, with a minimum central pressure of 910hPa and maximum winds of 65m/s. Notably, during its peak-intensity phase from September 24 to 28, despite fluctuations in pressure from 910hPa to 945hPa, it remained at the Severe Typhoon level or above, indicating exceptionally strong structural stability. Before landfall in Japan, intensity gradually weakened to the Typhoon level (40m/s, 960hPa), but it still posed significant destructive potential.
Compared with previous Typhoons of the same name, the 2012 Jelawat had exceptionally high intensity. Its peak pressure of 910hPa was far lower than that of the 2018 Jelawat (920hPa) and the 2000 Jelawat (950hPa), and it was significantly stronger than the same-named Typhoons of 2023 and 2006, which reached only the Tropical Storm level. Data show that the 2012 Jelawat was the strongest, longest-lasting, and most widespread episode among same-named Typhoons in recent years, and its prolonged Super Typhoon phase was rare in the same-name series.
