During a Typhoon's active period, live published values are operational positioning data. After the Typhoon ends, the CMA combines more complete observational data to produce the best-track dataset, which is generally used for academic research and historical rankings. Data sources: CMA Tropical Cyclone Best Track Dataset (compiled using IBTrACS v04r01); wind speeds are converted from knots to m/s and rounded.
Typhoon Jelawat trajectory
Path and Moving Characteristics
Typhoon Jelawat (2023), the 17th typhoon of 2023, had a relatively short life cycle, with observational data covering 8:00 on December 17 to 20:00 on December 18, 2023. Analysis of its track coordinates shows that it generally moved toward the WNW, then turned westward with a slight trend toward the NW. During the initial stage, from 08:00 to 14:00 on the 17th, the system was near latitude 7.5° and moved slowly west from 128.6°E to 128.1°E, at a relatively steady speed. Between 17:00 and 20:00 on the 17th, its latitude increased slightly to 7.6°N while it continued moving west to 127.7°E, indicating a slight northward component.
Go to 18 days after the path appears a noticeable turning point. 02:00 to 05:00, the systemins the path toward S adjustment, while the latitude remains at 7.8°N. However, starting from 08:00, the latitude gradually S drops to 11:00 at 7.5°N and 14:00 at 7.3°N, indicating that the guiding airflow may change, leading to the path toward S adjustment. It is worth noting that during the end of life history (18:00 to 20:00) , the latitude returns to 7.4°N and 7.7°N, the length rapidly W moves to 125.1°E, showing that the system is once again drawn by the NW toward airflow during the weakening.
Intensity evolution and historical comparison
在Intensity方面, “Jelawat”表现出显著的弱势特征. 在整个观测窗口期内, 其peak intensity仅为Tropical Storm级别, 最大持续wind speed维持在18m/s, 中心The minimum air pressure.为1000hPa. 从17日08:00至18日11:00, intensity 保持高度稳定, wind speed与气压均未发生显著变化. 然而, 自18日14:00起, 系统Intensity开始减弱, 降级为Tropical Depression, max wind 降至16m/s, Pressure上升至1002hPa, 直至观测结束仍维持此Intensity, 表明其结构松散, 缺乏进一步发展的能量支持.
与历史同名Typhoon 相比, 2023年“Jelawat”的Intensity极弱. 回顾历届数据, 2018年第3号Typhoon “Jelawat”曾达到Super Typhoon级别, minimum pressure 低至935hPa; 2012年第17号Typhoon “Jelawat”同样为Super Typhoon, minimum pressure 更是达到惊人的905hPa. 相比之下, 2023年该codeTyphoon 的The minimum air pressure. (1000hPa) 远高 at 历史Severe Typhoon案例, max wind (18m/s) 也远未达到Super Typhoon标准. 这种巨大的Intensity差异反映了不同年份大气环流背景及海温条件对Typhoon formed与发展的显著影响, 2023年“Jelawat”仅表现为一个短暂且微弱的Tropical Cyclone 过程.
