Typhoon Olive Trail Characteristics
Track and Turning Characteristics
Typhoon Olive (197116) 的生命史长达17天, 整体路径呈现典型的“NW行-N转-NE移”抛物线形态. formed初期, 系统位 at W.Pac平洋低纬度海域 (10.2°N, 153.2°E) , 受副热带高压S侧引导气流影响, 稳定 toward NW. 在7月27日至8月1日期间, 路径出现小幅摆动, 纬度在13.8°N至24°N之间波动, 经度持续W进至137.3°E附近, 显示其在接近关键转 toward 区时Moving速度放缓并积蓄能量.
The key turning point occurred in early August. At 24.8°N, 134.5°E on August 2, the center gradually shifted from heading northwest to due north, then turned northeast. After August 4, Typhoon Olive accelerated toward higher latitudes, eventually passing east of Japan and entering the open ocean. It made no landfall and remained at sea throughout its track until dissipating on August 10 at 43.1°N, 171.5°E. This long, widely arcing track reflected the combined effects of the subtropical high's ridge position and the flow ahead of the westerly wind trough.
Intensity evolution and historical comparison
Olive's intensity evolution featured a long period of strengthening followed by rapid weakening. It began as a tropical depression on July 24 at 1010hPa and gradually consolidated while moving west, upgrading to a tropical storm only on July 29. Its true rapid intensification occurred from August 1 to August 3, when the central pressure dropped sharply from 976hPa to 945hPa within 48 hours and the maximum wind speed increased to 40m/s. It reached its peak on August 4, recording a minimum central pressure of 936hPa and maximum wind speed of 45m/s, making it a severe typhoon.
The peak intensity was brief. After August 4, as the storm moved north of 30.5°N, increasing vertical wind shear and decreasing sea surface temperatures caused its intensity to fluctuate and decline. By August 6, when it reached 37.3°N, it had weakened into a severe tropical storm before rapidly transitioning into a tropical depression with the characteristics of an extratropical cyclone.
Compared with other storms of the same name, Olive in 1971 had a significantly higher peak intensity, with a central pressure of 936hPa, than Olive in 1978 at 955hPa and Olive in 1968 at 986hPa, though it was slightly weaker than Olive in 1960 at 950hPa. Note: The data must strictly follow the given text. Since the 1960 record is listed as 950hPa, Olive in 1971 had a lower central pressure and greater intensity. The data show that Olive in 1971 was the strongest of these four same-named typhoons by measured pressure, with the lowest central pressure, demonstrating exceptional rapid intensification potential.
