Typhoon Lorna (196916) 的生命周期始 at 1969年11月24日12时, 终 at 11月28日12时, 全程历时4天. 从空间轨迹来看, 该Typhoon formed at Northwest Pacific洋面 (初始Position9.9°N, 133.1°E) , 整体呈现 toward NW的Trend, 最终消散 at 15.7°N, 128.6°E附近. 在Moving过程中, 其路径表现出一定的复杂性: 初期 (11月24日至25日中午) 稳定 toward WNW; 随后在11月25日18时至26日00时期间, During由131.3°E略微E退至131.5°E, 出现短暂的停滞或微小幅度的 toward E调整; 11月26日12时后, The latitude出现短暂S落 (从14.3°N降至13.5°N) , 随后再次转为 toward NW. 整个生命周期内, 该Typhoon 未Landfall任何陆地, 始终在海上活动.
Lorna的Intensity变化经历了“ formed-增强-巅峰-减弱”的完整过程. 初始阶段为Nameless, max wind 12m/s. 经过约36h的缓慢加强, at 11月26日00时升级为Tropical Storm (20m/s) . 随后Intensity继续攀升, 在11月26日18时达到巅峰状态, 定性为Severe Tropical Storm, max wind 录得25m/s, 并维持该Intensity至11月27日00时. 巅峰期过后, 系统开始迅速减弱, 11月27日06时降格为Tropical Storm, 11月27日18时进一步 weakened into Nameless. 直至生命末期, wind speed逐渐回落至12m/s, 系统结构趋 at 消散. 值得注意的是, 数据中最低气压字段缺失, 仅能依据wind speed判断其Intensity等级.
In the 'Lorna' sequence named History, this process in 1969 was at the Intensity at the middle down level. Compared with the 1961 Lorna (top Super Typhoon) and the 1972 Lorna (top Tropical Storm), the 196916 Typhoon's Intensity was significantly weaker, only reaching the Severe Tropical Storm level. However, its Intensity was high at the 1976 Lorna (top only Nameless) . Compared with the 1966 Lorna (top Severe Tropical Storm), the two peak levels were the same, but the specific wind speed values required more detailed data to match.
