1977-12-31 18:00:00 After, Typhoon Mary gradually weakened and was numbered off on 1977-12-31 18:00:00 was numbered off; its lifecycle recorded 47 track points.
Typhoon Mary (197718) at 1977年12月20日06时在Northwest Pacific远洋海域 formed, 初始Position位 at 9.7°N, 179.4°E. 其生命史持续至12月31日18时, 全程未Landfall任何陆地. 从路径轨迹来看, 该Typhoon 整体呈现稳定的W行Trend, 但在The latitude上表现出显著的“先N后S”波动特征. formed初期, 系统 toward NW direction缓慢Moving, 纬度由9.7°N逐步攀升至12.8°N (12月24日18时) , 达到路径最N端. 随后, 受引导气流影响, Typhoon 转 toward SW, 纬度逐渐降低, 最终在9.1°N, 133.3°E附近消散. During方面, 系统从179.4°E持续 toward W跨越至133.3°E, 横跨约46个经度, 显示其在低纬度地区具有较长的维持Time和稳定的W移分量.
Mary的Intensity变化经历了完整的“增强-巅峰-减弱”周期. formed初期为Nameless (15m/s) , 随后迅速加强, at 12月23日06时发展为Typhoon (35m/s) . 在12月24日至25日期间, 系统Go to 快速增强阶段, max wind 从38m/s跃升至48m/s, 达到Severe Typhoon级别, 这也是其生命史中的peak intensity. 值得注意的是, 巅峰状态维持Time较短, 12月25日12时达到48m/s后, 系统随即开始显著减弱. 12月26日06时, wind speed骤降至30m/s, 降级为Severe Tropical Storm. 此后, 尽管在12月29日至30日期间Intensity略有反复 (维持在28m/s的Severe Tropical Storm级别) , 但整体呈衰减Trend, 最终 at 12月31日12时 weakened into Nameless并结束观测.
In comparison to Mary (196804) and Mary (196513) the two times reached the 'Super Typhoon' level of strong systems, Mary's peak intensity (Severe Typhoon, 48m/s) in 1977 was significantly weak. at the same time, its intensity was also low at or flat at 1974 Mary (197413) and 1960 Mary (196001) 'Typhoon' level records.
