Typhoon Ruth, international code 198702, international name RUTH, 1987 Northwest Pacific typhoon. Formed: 1987-06-17 00:00:00, ended: 1987-06-19 18:00:00. Peak intensity: Nameless, minimum central pressure: 992 hPa, max wind: 17m/s.
Typhoon Ruth at 1987-06-17 00:00:00 at 19.1°N, 116.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Nameless intensity with max winds of 17 m/s (~61 km/h) and a minimum central pressure of 992hPa, recorded at 1987-06-18 18:00:00.
1987-06-19 18:00:00 After, Typhoon Ruth gradually weakened and was numbered off on 1987-06-19 18:00:00 was numbered off; its lifecycle recorded 12 track points.
1987年第2号Typhoon “Ruth”的生命史较短, 从 formed至消散历时约66h. 根据观测数据, 该系统始终维持NamelessIntensity, 未发展为更高等级的Tropical Storm或Typhoon , 且全程无Landfall记录. 其路径整体呈现稳定的NW toward MovingTrend. 初始阶段 (6月17日00时至12时) , 系统位 at S海NE部海域 (约19.1°N, 116.8°E附近) , Moving速度相对缓慢, The latitude变化微小, During toward W推进约0.9度. 随后, 系统加速 toward NW direction行进, 穿Vietnam海N部海域. 在6月17日18时至6月19日18日期间, 其Center从18.7°N持续N移至23°N, 经度从115.3°EW移至108.3°E, 横跨约7个经度. 路径曲线平滑, 未见明显的折 toward 或停滞现象, 表明引导气流较为稳定单一. 最终, 该系统在接近ChinaS部coastal 但未Landfall的情况下, at N部湾W侧海域逐渐减弱消散.
In Intensity, “Ruth” shows typical weak tropical cyclone characteristics. Its Max Wind is only 17m/s, appearing at 18h on June 18th (20.8°N, 112.8°E) , at this time reaching the peak intensity in life history. Before this, wind speedined between 12-15m/s; after this, with the system toward NWMoving and approaching the edge of the land, the intensity began to fluctuate, until the last moment before the dispersion (June 19th, 18h) wind speed has fallen to 10m/s. by at lack of air pressure data, can only be judged by wind speed its structure loose, the degree of organization is lower.
Historical records show that in 1991 'Ruth' had reached the Super Typhoon level, in 1980 and 1983 the same name 'Typhoon' also reached the Typhoon and Severe Tropical Storm Intensity, respectively, even the weaker 1994 'Ruth' also reached the Tropical Storm level.
