Typhoon Polly, international code 197415, international name POLLY, 1974 Northwest Pacific typhoon. Formed: 1974-08-24 00:00:00, ended: 1974-09-08 12:00:00. Peak intensity: Severe Typhoon, minimum central pressure: 950 hPa, max wind: 48m/s.
Typhoon Polly at 1974-08-24 00:00:00 at 18.2°N, 153.8°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Severe Typhoon intensity with max winds of 48 m/s (~173 km/h) and a minimum central pressure of 950hPa, recorded at 1974-08-28 18:00:00.
1974-09-08 12:00:00 After, Typhoon Polly gradually weakened and was numbered off on 1974-09-08 12:00:00 was numbered off; its lifecycle recorded 63 track points.
Typhoon Polly (197415) 的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW行-转 toward NE”的抛物线形态. formed初期 (8月24日至26日) , 系统在低The latitude海域缓慢 toward WS, 随后逐渐调整为稳定的NW toward 路径. 在8月27日至29日期间, Typhoon 维持NW行进 direction, 纬度从18.8°N迅速提升至23.7°N, During由144.2°EW进至141.2°E, 显示出较强的引导气流作用.
路径的关键转折点出现在8月30日至31日之间. 随着系统N上至30°N附近的高The latitude区域, 受W风带影响, Moving direction发生显著改变, 由NW转为NE direction. 此后, Typhoon 加速 toward NE, 穿越Japan以E海域, 最终Go to 中高纬度开阔洋面. 整个生命周期长达15天半, track points多达63个, 表明其结构在大部分Time内保持完整, 未受陆地地形摩擦的直接干扰, 全程无Landfall记录.
After intensified into Tropical Storm on August 26, the system quickly erupted, upgraded from Tropical Storm to Typhoon in only about 36h, and at August 29 reached peak intensity, max wind to 48m/s, qualified as Severe Typhoon.
在与同名Typhoon 的横 toward 对比中, 1974年Polly的peak intensity (Severe Typhoon, 48m/s) 显著高 at 1978年, 1971年及1968年的同名Typhoon (均为Severe Tropical Storm或Tropical Storm级别) . 其与1995年Polly同为Severe Typhoon级别, 显示出该命名序列中存在产生高IntensityTyphoon 的潜势. 总体而言, 1974年Polly属 at 生命史长, peak intensity高且路径典型的远洋Severe Typhoon.
