Characteristics of Typhoon Clara
Track and Movement Characteristics
Typhoon Clara (198420) at 1984年11月14日凌晨在Northwest Pacific低纬度海域 formed, 初始Position位 at lat 4.7°N, 156.6°附近. 在整个生命史中, 该Typhoon 呈现出典型的“W行后转 toward NE”的抛物线型路径特征. formed初期, 系统稳定 toward WNW, 横跨广阔洋面, 直至11月19日14时到达lat 17.1°N, 132.2°附近. 此后, 受大气环流引导气流变化影响, typhoon track发生显著转折, 由W行转为 toward N, 进而加速 toward NE. 整个过程中, Typhoon 未Landfall任何land, 始终在海上活动, 最终 at 11月22日上午在lng 151.1°附近减弱消散. 从坐标序列分析, 其转 toward 点大致位 at lat 17°至19°N, 132°至134°之间的海域, 转 toward 后移速明显加快, 经纬度跨度增大.
Intensity evolution and historical comparison
Clara underwent a complete cycle of formation, intensification, peak intensity, and weakening. It strengthened rapidly after formation, reaching severe typhoon status in about four days. It became a typhoon on the afternoon of November 17 and reached severe typhoon intensity in the early morning of November 18. Its lifetime peak occurred from November 20 to 21, when its minimum central pressure fell to 940 hPa and its maximum wind speed reached 50 m/s. Despite moving gradually northward during this peak phase, it did not immediately weaken and recorded its lowest pressure at 14:00 UTC on November 20. It then weakened rapidly as it moved toward higher latitudes and entered an unfavorable environment. Within 24 hours, its wind speed dropped from 50 to 30 m/s and its pressure rose by 30 hPa, indicating significant effects from extratropical transition or cold sea waters.
Compared with previous storms of the same name, Clara in 1984 reached a moderately high intensity. It was much stronger than Clara in 1988, which peaked as a tropical storm with a central pressure of 995 hPa, and Clara in 1976, which reached typhoon intensity with a central pressure of 978 hPa. Compared with Clara in 1967, a severe typhoon with a central pressure of 962 hPa, the 1984 storm had lower pressure and stronger winds. However, it remained weaker than Clara in 1981, a super typhoon with a central pressure of 924 hPa. Overall, Clara in 1984 was a well-structured, intense remote-ocean typhoon with a typical track.
