Typhoon Peggy Trail Characteristics
Track and Movement Characteristics
Typhoon Peggy (198607) began over the open waters of the Northwest Pacific and followed a generally steady west-northwest track, with no notable turns or reversals. From its formation near 13°N, 162°E to dissipation near 23°N, 104°E, the system continued moving westward. Between June 30 and July 5, its latitude changed little, ranging from 13°N to 15°N, while it moved rapidly westward at an average of about 4–5 degrees of longitude per day. After July 6, as it approached the Philippines over the eastern waters, its track began a slight northward shift, with latitude rising from 15.8°N to 23°N by July 14. Despite this northward component, it never made a typical recurving turn and instead continued toward the Asian mainland. The typhoon made no landfall and eventually weakened and dissipated near the coast of Vietnam. Its track was long, straight, and entirely over the sea.
Intensity evolution and historical comparison
Peggy的Intensity演变经历了典型的“快速增强—巅峰维持—缓慢减弱”过程. 系统在7月4日由Tropical Depression迅速 intensified into Severe Tropical Storm, 随后在48h内爆发式增强, at 7月7日达到巅峰状态, 中心最低气压降至900hPa, max wind 达65m/s, 确立为Super Typhoon等级. 这一极低的气压值表明其核心结构极为紧密且能量巨大. 巅峰状态维持约24h后, 自7月8日起Intensity开始波动下降, 气压回升至920hPa以上, wind speed回落. Go to 7月10日后, 减弱速度加快, 由Typhoon 级迅速降格为Severe Tropical Storm及Tropical Depression.
Compared with other storms of the same name, Peggy’s intensity in 1986 was notably greater. The 1994 typhoon reached only typhoon status, with a central pressure of 965 hPa, while the 1989 typhoon peaked at tropical storm strength with a central pressure of 995 hPa. Although the 1990 typhoon also reached super typhoon status with a minimum central pressure of 910 hPa, Peggy in 1986 had a lower central pressure of 900 hPa and stronger maximum wind speeds of 65 m/s, demonstrating more extreme intensity. It remains a notable severe typhoon in the historical series of storms named Peggy.
