1971 Typhoon Past typhoons named Nadine Typhoon archive

[Quick Archive Overview]Typhoon Nadine (No. 197115, a historical number used before 1981) was a 1971 Northwest Pacific typhoon. It reached super typhoon intensity, with maximum winds of 70 m/s and a minimum central pressure of 896 hPa. It did not make landfall in China, was numbered off on July 27, 1971, and had 35 recorded track points throughout its lifetime.

Numbering note: The internationally unified numbering system for the Northwest Pacific has been implemented by the JMA in Japan, the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1971. The number 197115 is the historical number retained by the CMA, while the numbers assigned that year by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities may have differed and cannot be compared directly.
Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

Typhoon Nadine Trail Characteristics

Path and Moving Characteristics

Typhoon Nadine (197115) at 1971年7月19日08时在Northwest Pacific洋面 formed, 初始Position为11.3°N, 142.8°E. 在其全生命周期内, 该Typhoon 整体呈现稳定的NW toward MovingTrend, 未出现明显的路径转折或Landfall行为. 从 formed至7月24日巅峰期, 系统中心持续 toward NW direction推进, 纬度由11.3°N升至20.1°N, 经度由142.8°EW移至126.6°E, 平均移速较快且轨迹平滑. 7月25日后, 随着纬度进一步N抬至29°N, 路径 direction逐渐转为N及NE direction, 最终 at 7月27日20时在115°E附近消散. 整个生命史长达8天半, track pointstotal 计35个, 显示其为一个长寿命, 远About 离Moving的远洋Typhoon 系统. 由 at 全程无Landfall记录, 其对land直接风雨影响相对有限, 主要活动区域集中在开阔洋面.

Intensity Evolution Analysis

Nadine的Intensity演变经历了典型的“快速增强-巅峰维持-迅速减弱”过程. formed初期为Tropical Depression, 7月20日晚 intensified into Tropical Storm, 随后在48h内连续跨越Severe Tropical Storm, Typhoon 及Severe Typhoon等级. 7月23日至24日是其爆发式增强期, Pressure从942hPa骤降至历史极低的896hPa, max wind 达到70m/s, 确立为Super Typhoon级别. 值得注意的是, 在7月24日08时至20时期间, 尽管Pressure继续下探至最低值896hPa, 但Max Wind维持在70m/s, 显示其核心结构极度紧密且能量充沛. 然而, 自7月25日08时起, 系统Intensity开始显著衰退, 气压回升至920hPa, wind speed降至60m/s. Go to 高纬度海域后, 减弱速度加快, 仅用不到两天Time便由Super Typhoon降级为Tropical Depression, 反映出环境场对其支撑作用的快速丧失.

Same-Name Comparison

在“Nadine”这一命名序列的History中, 1971年的Nadine表现出压倒性的Intensity优势. 对比数据显示, 1974年Nadine巅峰仅为Severe Tropical Storm (982hPa) , 1965年Nadine为Severe Tropical Storm (990hPa) , 1960年Nadine为Typhoon (985hPa) , 1968年Nadine虽达Typhoon 级别但最低气压为972hPa. 相比之下, 1971年Nadine的最低气压 (896hPa) 远低 at 其他历届同名Typhoon , max wind (70m/s) 也显著高 at 其他年份的peak intensity. 这表明1971年Nadine是该命名序列中最为强劲, 破坏潜力最大的一个Typhoon 个体, 其Intensity特征在历史同期同类系统中具有显著的极端性.

The internationally unified numbering system for the Northwest Pacific began in 1981. Before then, individual agencies used separate numbering systems, so the numbers assigned by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological authorities to the same typhoon could differ and cannot be compared directly.

Where did Typhoon Nadine’s track data come from?

Track data sources: China Meteorological Administration Tropical Cyclone Best Track Dataset (CMA-STI); wind speeds are 2-minute sustained wind speeds.

What is the highest level of Typhoon Nadine?

Typhoon Nadine peak intensity is Super Typhoon, max wind 70m/s, minimum central pressure 896 hPa.

Typhoon Nadine Landfall?

According to records, Typhoon Nadine is not in our coastal landfall.
