1973 Typhoon Past typhoons named Nora Typhoon archive

[Quick Archive Overview]Typhoon Nora (No. 197315, the historical number used before 1981) was a 1973 northwestern Pacific typhoon. It peaked as a super typhoon, with maximum winds of 70 m/s and a minimum central pressure of 875 hPa. It did not make landfall in China and was numbered off on October 10, 1973. A total of 36 track points were recorded throughout its lifetime.

Numbering note: International numbering in the northwestern Pacific has been assigned by the JMA in Japan, the regional specialized meteorological center for East Asia, since 1981. This system did not exist in 1973. The number 197315 is the historical identifier used by the CMA. In that year, the identifiers assigned to the same typhoon by the JMA in Japan, the Joint Typhoon Warning Center in the United States, and China’s meteorological agencies may differ and therefore cannot be compared directly.

Path and Moving Characteristics

Typhoon Nora (197315) at 1973年10月2日02:00在Philippines以E洋面 formed, 初始Position为11.1°N, 135.9°E. 其整体Moving路径呈现显著的NW toward Trend, 全程未发生明显的转 toward 或折返. 从 formed至10月5日, Typhoon 主要维持在W行N的路径上, 纬度从11.1°N缓慢N抬至14.2°N, 经度由135.9°EW移至129.6°E. Go to 10月6日后, 随着系统Intensity达到巅峰, 其 toward N分量略有增加, 路径指 toward NNW direction, 直至10月10日消散 at 25.8°N, 116.2°E附近. 值得注意的是, 该Typhoon 在整个生命周期内无Landfall记录, 始终在海上活动, 最终在Taiwan海峡以E海域减弱消散.

Intensity Evolution Analysis

Nora的Intensity演变经历了快速增强, 巅峰维持及逐渐减弱三个阶段. formed初期, 系统在24h内由Tropical Depression迅速 intensified into Severe Tropical Storm, 气压降至985hPa. 10月4日至5日, Typhoon Go to 快速增强期, max wind 从40m/s跃升至60m/s, Pressure急剧下降至920hPa. 10月6日14:00, Nora达到生命史中的peak intensity, 录得最低气压875hPa及Max Wind70m/s, 评定为Super Typhoon. 此后, 虽然Intensity有所波动, 但在10月7日至8日期间仍维持Super Typhoon等级 (wind speed55-65m/s) . 10月8日20:00后, 系统开始显著减弱, wind speed降至35m/s并维持至10月10日早晨, 最终在10月10日20:00 weakened into Tropical Depression并结束观测.

Same-Name Comparison

与历史上其他名为“Nora”的Typhoon 相比, 1973年的Nora在Intensity上具有压倒性优势. 数据显示, 1976年Nora巅峰仅为Severe Tropical Storm (990hPa) , 1964年Nora同为Severe Tropical Storm (997hPa) , 1962年Nora虽达Typhoon 级但最低气压为968hPa, 1967年Nora巅峰气压为982hPa. 相比之下, 1973年Nora的最低气压 (875hPa) 远低 at 上述历届同名Typhoon , max wind (70m/s) 也显著更高, 是统计样本中Intensity最强的一次“Nora”Typhoon 过程.
