Typhoon Lorna trajectory analysis
Track and Movement Characteristics
Typhoon Lorna (197602) 的生命周期始 at 1976年2月25日00时, formedPosition位 at lat 4.4°N, 163.3°的Northwest Pacific低纬度海域. 在初始阶段, 该系统呈现稳定的WNWTrend. 从2月25日至2月28日期间, 其中心坐标由(4.4°N, 163.3°E)持续 toward NW direction推移至(9.8°N, 147.9°E), 纬度显著N抬, 经度大幅W进, 显示出受低层引导气流影响的典型W行特征.
It is worth noting that after the Typhoon reached the maximum N-end latitude of 9.8°N on February 28 at 12 a.m., there was a noticeable turn of the path. Since February 29 a.m., the system turned toward WSW, the latitude began to slowly S fall, from 9.0°N gradually dropped to 8.5°N on March 3, while the lengthined the continuous toward W propulsion, until the lng 131.3° dispersed.
Intensity evolution and historical comparison
在Intensity方面, Lorna全程维持Tropical Depression等级, 未曾发展为Tropical Storm及以上级别. 其Max Wind在生命初期稳定在12m/s, at 2月28日00时增强至15m/s, 并在同日12时达到peak intensity17m/s. 此后, 系统Go to 减弱阶段, wind speed逐步回落至15m/s, 12m/s, 并最终在生命末期维持在10m/s左右. 由 at 数据缺失, minimum pressure 值无法具体量化, 但wind speed变化清晰反映了其“弱增强, 缓减弱”的生命史特征.
Historical records show that in 1961 Lorna had reached the Super Typhoon level, in 1972 Lorna reached the Typhoon level, in 1966 and 1969 Lorna also reached the Severe Tropical Storm level. In comparison, in 1976 Lorna only stayed in the Tropical Depression phase, max wind far low at other years of the same name Typhoon peak intensity, belonging to the weaker 'Lorna' Typhoon individual.

FAQ
Typhoon Lorna was the 1976 Typhoon.
Typhoon Lorna's 197602 is a historical number continued by the CMA, meaning No. 2 of 1976. Its international name was LORNA. The internationally unified numbering system for the Northwest Pacific did not begin until 1981. Before then, different agencies used their own numbering systems, including the JMA, the Joint Typhoon Warning Center in the United States, and China's meteorological agencies. Thus, the numbers assigned to the same typhoon may differ and cannot be compared directly.
Where does the track data for Typhoon Lorna 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 most powerful typhoon Lorna?
