Typhoon Wynne trajectory
Track and Turning Characteristics
Typhoon Wynne (198706) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行进—转 toward NE”的抛物线形态. formed初期 (7月22日至24日) , 系统自低纬度洋面 (9°N, 169°E) toward NW direction稳定Moving, 横穿马里亚纳群岛以E海域. 在7月27日02:00前后, Typhoon 中心抵达lat 19.5°N, 140.5°附近, 此时达到路径的最W端, 随后路径曲率发生显著变化, 开始由NW toward 转为N, 进而转 toward NE. 这一转 toward 过程平滑且连续, 未出现停滞或打转现象. 转 toward 后, Typhoon 逐渐远离land, 最终 at 8月1日20:00 at 35°N, 153.8°附近 weakened into Tropical Depression并结束观测. 全生命周期内无Landfall记录, 主要活动区域集中在开阔洋面.
Intensity evolution and historical comparison
Wynne's intensity evolution underwent three stages: rapid intensification, peak maintenance, and gradual weakening. Starting as a tropical depression, the system rapidly intensified into a typhoon within 48 hours and upgraded to a super typhoon on July 25. Its peak state occurred at 02:00 on July 27, when the central minimum pressure dropped to 920 hPa and maximum winds reached 65 m/s. Notably, over the following ~48 hours (until 14:00 on July 28), although pressure fluctuated slightly (920–928 hPa), the system remained at super typhoon strength, demonstrating strong structural stability. Upon entering higher-latitude waters, influenced by environmental conditions, intensity declined significantly from July 29 onward, with pressure rising above 975 hPa and wind speeds dropping sharply.
Compared to historical namesakes, the intensity of 1987's Wynne fell between that of the 1980 and 1984 typhoons of the same name. Typhoon Wynne (198019) reached an extremely low pressure of 890 hPa, indicating greater intensity; whereas Typhoon Wynne (198402) peaked only as a severe tropical storm (970 hPa). With a minimum pressure of 920 hPa and maximum winds of 65 m/s, the 1987 Wynne exhibited typical characteristics of a severe typhoon. Its peak intensity far exceeded the 1984 case but was slightly less than the extreme 1980 case.
