Characteristics of Typhoon Virginia
Track and Movement Characteristics
1978年第8号Typhoon “Virginia”的生命史始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW-转 toward NE”抛物线型轨迹. formed初期 (7月22日至24日) , 系统位 at 150°E以E洋面, 稳定 toward NW, 纬度从13.7°N迅速N抬至16.6°N. 7月25日至27日期间, 受副热带高压引导, 其Moving direction逐渐转为W及WNW, 经度由150.5°EW进至147°E附近, 此阶段为路径的最W端.
7月28日至29日, 系统在147°E附近出现明显的路径转折迹象, Moving速度放缓并开始 toward N分量增加. 随后, 受W风带影响, Typhoon at 7月30日后加速 toward NE, 经度重新E退至145°E以E. 最终, 该系统在8月2日移至41.8°N, 151°E的高纬度海域时减弱消散. 整个生命周期中, 该Typhoon 未Landfall任何land, 始终在海上活动, 属 at 典型的远洋转 toward 型Typhoon .
Intensity evolution and historical comparison
在Intensity变化方面, “Virginia”经历了完整的 formed, 增强, 巅峰维持及减弱过程. 7月22日以Tropical Depression formed后, intensity 稳步提升, at 7月24日发展为Tropical Storm, 7月25日 intensified into Severe Tropical Storm. 7月28日升级为Typhoon 级别, 并 at 7月29日达到生命史巅峰, max wind 录得35m/s. 此后, 随着纬度升高及Go to 高纬冷海区, intensity 开始波动下降, 7月31日 weakened into Severe Tropical Storm, 8月2日进一步降级为Tropical Storm及Tropical Depression.
与同名History相比, 1978年“Virginia”的Intensity表现中等. 相较 at 1971年第20号同名Typhoon ( peak intensity is Super Typhoon) 和1960年第10号同名Typhoon ( peak intensity is Severe Typhoon) , 1978年的系统Intensity明显偏弱, 仅达到CommonTyphoon 级别. 然而, 其Intensity仍高 at 1963年第5号同名Typhoon (巅峰仅为Severe Tropical Storm) . 这表明虽然“Virginia”这一命名曾多次用 at 不同Intensity的Tropical Cyclone , 但1978年的个案属 at 中等Intensity范畴, 其显著特征在 at 较长的海上寿命及完整的中高纬度转 toward 过程, 而非极端的破坏性Intensity.
