Characteristics of Typhoon Guchol
Track and Turning Characteristics
Typhoon Guchol (201204) 的生命史长达12天, 整体路径呈现典型的“NW行-N转-NE移”抛物线形态. formed初期 (6月10日至13日) , 系统在低纬度海域 (7.5°N-10.7°N) 稳定 toward WNW, 经度从148.6°E迅速W移至137.9°E. 6月14日至15日, 路径出现短Pause滞并略微W折, 随后在Philippines以E海域开始显著N抬.
The key turning process occurred from June 16 to 18. As its latitude rose rapidly from 14.9°N to 25.3°N, the system was affected by flow along the edge of the subtropical high and the westerlies. Its movement shifted from northwest to north, then turned toward the northeast. At 16:15 on June 19, the system made landfall along the southern coast of Wakayama County, by which time its center had reached the mid-latitudes at 34.9°N. After landfall, Guchol accelerated toward the northeast, crossed Honshu, Japan, and entered the northwestern Pacific. It eventually weakened and dissipated over the high-latitude waters near 42.7°N on June 22. The storm covered an exceptionally broad range, developing from a tropical depression into a severe typhoon that affected Japan’s eastern coast and displaying the early characteristics of extratropical transition.
Intensity evolution and historical comparison
Guchol underwent a dramatic intensification and decay cycle. It initially strengthened slowly and did not reach severe tropical storm intensity until June 14. However, within 24 hours from June 15 to 16, its maximum winds surged from 33 m/s to 55 m/s and its central pressure dropped sharply to 935 hPa, rapidly making it a super typhoon. From June 16 to 17, the system maintained its peak intensity near 19.7°N, with winds of 55 m/s and a central pressure of 935 hPa. Although the records indicate that its peak reached 60 m/s and 915 hPa, the sampled points show that its structure remained compact during its northward movement.
As latitude increased after landfall, the storm’s intensity declined rapidly. On June 18, Guchol weakened to a severe typhoon and made landfall as a severe tropical storm with winds of 30 m/s. It further weakened to a tropical depression 24 hours later. Compared with previous storms of the same name, the 2012 Guchol had a commanding advantage in intensity. The 2023 Guchol peaked only at typhoon intensity with a central pressure of 960 hPa, while the 2017 and 2005 storms did not even exceed severe tropical storm intensity, with central pressures of 998 hPa and 985 hPa, respectively. The 2012 Guchol was the only storm of the same name to reach super typhoon intensity in nearly two decades. Its minimum pressure was 45 hPa lower than that of the second-strongest version in 2023, indicating exceptionally strong energy release.
