Typhoon Emma trajectory analysis
Path and Moving Characteristics
Typhoon Emma (196720) formed at Northwest Pacific低纬度海域, 初始Position位 at lat 6.5°N, 150°附近. 在整个生命史中, 该Typhoon 呈现出稳定的NW toward MovingTrend, 未出现明显的路径转折或回旋现象. 从10月30日08:00至11月8日20:00, 其中心坐标由lng 150°持续W移至lng 109.3°, 纬度由lat 6.5°N抬至lat 21.8°. 这种长About 离, 单 toward 性的Moving轨迹表明, 该系统主要受副热带高压S侧E气流的引导, 且引导气流稳定强劲. 值得注意的是, 尽管路径跨度极大, 但该Typhoon 全程无Landfall记录, 始终在海上活动, 最终 at 21.8°N, 109.3°附近减弱消散.
Intensity Evolution Analysis
Emma的Intensity变化经历了典型的“快速增强—巅峰维持—逐渐减弱”过程. formed初期为Tropical Depression (1008hPa) , 随后在48h内迅速加强, at 10月31日20:00达到Severe Tropical Storm级别. 11月1日至11月2日期间, 系统经历爆发式增强, Pressure从971hPa骤降至937hPa, wind speed由45m/s跃升至60m/s. 11月3日02:00, Typhoon 达到巅峰状态, 中心最低气压录得912hPa, max wind 达65m/s, 确认为Super Typhoon等级. 然而, 巅峰状态维持Time较短, 仅约18h后, 受环境因素影响, intensity 开始显著回落. 11月3日20:00气压回升至956hPa, wind speed降至45m/s. 此后, 随着纬度升高及可能的垂直风切变影响, Typhoon 持续减弱, 直至11月8日20:00降格为Tropical Depression (1010hPa) , 完成生命循环.
Same-Name Comparison
In the history of the Emma name, the 1967 typhoon displayed tremendous destructive potential. Compared with the three other typhoons of the same name in 1977 (966hPa), 1974 (988hPa), and 1965 (993hPa), Emma’s peak intensity in 1967 far exceeded theirs; all three reached only severe tropical storm status. Even compared with Typhoon Emma of 1959 (958hPa), which also reached super typhoon intensity, Emma in 1967 had lower pressure (912hPa versus 958hPa) and higher maximum winds (65m/s versus the implied lower wind speed), making it an exceptionally intense storm among those sharing its name.

FAQ
Emma is the 1967 Typhoon.
The designation 196720 for Typhoon Emma is the historical identifier retained by the CMA, meaning the 20th typhoon of 1967, while its international name was EMMA. The internationally unified numbering system for the Northwest Pacific did not begin until 1981. Before then, agencies used their own numbering systems, so the numbers assigned by the JMA, the Joint Typhoon Warning Center of the United States, and China’s meteorological authorities may differ for the same typhoon and cannot be directly compared.
Where does the track data for Typhoon Emma 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 Emma?
Typhoon Emma peak intensity is Super Typhoon, max wind 65m/s, minimum central pressure 912 hPa.
Typhoon Emma Landfall?
According to records, Typhoon Emma is not in our coastal landfall.
Where can I view typhoon Emma's live track map?
