Typhoon Opal, international code 197316, international name OPAL, 1973 Northwest Pacific typhoon. Formed: 1973-10-04 00:00:00, ended: 1973-10-09 12:00:00. Peak intensity: Typhoon , minimum central pressure: 970 hPa, max wind: 38m/s.
Typhoon Opal at 1973-10-04 00:00:00 at 10.8°N, 114.7°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 970hPa, recorded at 1973-10-06 06:00:00.
1973-10-09 12:00:00 After, Typhoon Opal gradually weakened and was numbered off on 1973-10-09 12:00:00 was numbered off; its lifecycle recorded 23 track points.
Typhoon Opal (197316) 的生命史始 at S海中部海域, 整体路径呈现显著的W行特征. formed初期 (10月4日) , 系统位 at lat 10.8°N, 114.7°附近, 随后稳定 toward WNW. 在10月5日至10月7日期间, Typhoon 主体维持在W沙群岛以S海域活动, The latitude从12.2°N缓慢N抬至14.3°N, During则持续W移. 值得注意的是, 10月7日06:00至10月8日12:00期间, Typhoon 中心纬度基本停滞在14.3°N附近, 而经度由111.1°E快速W移至108.3°E, 显示出明显的纯W toward Moving分量, 未出现典型的N上转 toward 或LandfallChina大陆coastal 的迹象. 最终, 该系统 at 10月9日中午在Vietnam以E近海 (14.1°N, 107°E) 减弱消散, 全程无Landfall记录.
The Typhoon underwent a complete 'formed-enhanced-top-weakened' process. October 4th 12:00 intensified into Tropical Storm, October 5th 18:00 reached the Typhoon level. Intensity climbing period mainly concentrated on October 5th to 6th, max wind rapidly increased from 23m/s to 38m/s. October 6th 06:00 and October 7th 00:00 to 06:00, Typhoon twice reached 38m/s peak intensity, andined about 48h on Typhoon level Intensity. October 7th 18:00 after, as the system W line continued, intensity began to decline significantly, from Typhoon to Severe Tropical Storm, and entered at October 8:00:00 back to Tropical Storm.
Its peak intensity is Typhoon grade (38m/s), weak at 1967 (Super Typhoon) and Severe Typhoon of the same name in 1997 (Severe Typhoon), but significantly strong at 1976 (only Nameless) and 1970 (Severe Tropical Storm) systems.
