Typhoon Helen, international code 199505, international name HELEN, 1995 Northwest Pacific typhoon. Formed: 1995-08-03 00:00:00, ended: 1995-08-13 00:00:00. Peak intensity: Typhoon , minimum central pressure: 985 hPa, max wind: 35m/s.
Typhoon Helen at 1995-08-03 00:00:00 at 12°N, 145.3°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 35 m/s (~126 km/h) and a minimum central pressure of 985hPa, recorded at 1995-08-12 00:00:00.
Typhoon Helen gradually weakened and was numbered off on 1995-08-13 00:00:00 was numbered off; its lifecycle recorded 41 track points.
Typhoon Helen (199505) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现显著的W行转N折特征. formed初期 (8月3日至6日) , 系统位 at 12°N至14.5°N, 145.3°E至134.5°E之间, 维持稳定的W toward Moving, 日均During跨度约2至3度, 显示其受副热带高压S侧引导气流控制明显. 8月7日后, 随着The latitude逐渐N抬至15.1°N, 路径开始显现NW toward 分量.
When the system Go to S Sea NE Sea Area (about 119°E-117°E), the latitude fluctuates slightly between 18.2°N and 19.1°N, then at August 11 significantly accelerates toward N advance. From August 11 06:00 at 19.8°N to August 13 00:00 at 26°N, the system moves more than 6 latitudes within less than two days of Time N, indicating that it has been disconnected from the low-latitude wind belt, turning by the W wind belt or sub-high-marginal air flow guided by N. A full landfall record, eventually dispersed near 26°N, 115.2°E.
Helen的Intensity演变具有“长期维持弱态, 后期快速爆发”的特点. 在长达6天的Time里 (8月3日至8月9日18:00前) , 系统始终维持在Nameless或刚达到Tropical Storm下限的状态, max wind 仅在7m/s至17m/s之间徘徊. 然而, Go to S海后其结构迅速整合, 8月9日18:00增强为Tropical Storm (20m/s) , 随后在48h内连续跳级, at 8月11日06:00达到Severe Tropical Storm级别 (30m/s) , 并在8月12日00:00达到peak intensity, 确认为Typhoon 级, max wind 35m/s.
At only 18h after reaching the peak, the center of Max Wind fell to 15m/s, again falling back to the Nameless standard, showing that it suffered a strong vertical wind intersection or dry air invasion during the process on N, leading to the rapid collapse of the structure.
Helen's peak intensity (Typhoon level, 35m/s) in 1995 was significantly higher compared to the historical typhoon at the same name system in 1992, 1975 and 1966 (both Tropical Storm or Severe Tropical Storm level), but weak at 1972 to reach Super Typhoon level Helen.
