Typhoon Roy trajectory analysis
Track and Movement Characteristics
Typhoon Roy (198801) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的W行Trend, 未发生明显的N上转 toward 或Landfall行为. formed初期 (1月8日) , 系统位 at 173°E附近, 随后迅速 toward WMoving, 经度在4天内从173°E推进至160°E, Moving速度较快. Go to 1月10日后, 随着纬度从8.7°N逐渐N抬至15°N, 路径略呈WNW走 toward . 值得注意的是, 在1月13日达到最N端纬度15°N后, 系统路径出现轻微S折迹象, 1月14日至18日期间, 纬度维持在12.7°N至14.7°N之间波动, 并最终 toward SW direction偏移, at 1月18日消散 at 114°E附近. 全生命周期内, 该Typhoon 始终在洋面上活动, 无Landfall记录, 路径平滑且连续, 体现了典型的Tropical Cyclone 在副热带高压S侧引导气流下的稳定W行特征.
Intensity evolution and historical comparison
Roy's intensity evolution underwent three phases: rapid intensification, prolonged peak maintenance, and gradual weakening. Starting as a tropical depression (15 m/s, 1000 hPa) on January 8, the system rapidly intensified into a severe tropical storm within 48 hours and upgraded to a typhoon on January 10. In the early hours of January 11, its intensity surged to severe typhoon level with maximum winds reaching 50 m/s and minimum pressure dropping to 945 hPa. From then until January 13, Roy maintained severe typhoon intensity for approximately 60 hours, during which the minimum pressure further dropped to 940 hPa while maximum winds remained at 50 m/s, demonstrating strong core stability. From January 14, influenced by environmental factors, intensity began to fluctuate and decline. Although it briefly rebounded to 45 m/s on January 15, the overall trend turned to weakening, and it finally downgraded to a tropical depression and dissipated on January 18.
Compared with the typhoon of the same name, the intensity of Roy in 1988 was significantly higher than that of Typhoon Roy (No. 11) in 1981. The peak intensity of Roy in 1981 was only a severe tropical storm with a minimum pressure of 986 hPa. In contrast, Roy in 1988 not only reached severe typhoon level but also had a lower minimum pressure of 940 hPa and maximum winds 25 m/s higher, indicating that the 1988 system had a deeper convective structure and stronger energy release capability.
