The SummaryTyphoon Jelawat (international code 202317) is a 2023 Northwest Pacific typhoon; peak intensity Tropical Storm, max wind 18m/s, minimum central pressure 1000hPa, not in China Landfall, 2023-12-18 was numbered off, recorded 11 track points.
Typhoon Jelawat, international code 202317, international name Jelawat, 2023 Northwest Pacific typhoon. Formed: 2023-12-17 08:00:00, ended: 2023-12-18 20:00:00. Peak intensity: Tropical Storm, minimum central pressure: 1000 hPa, max wind: 18m/s.
Typhoon Jelawat at 2023-12-17 08:00:00 at 7.5°N, 128.6°E over the Northwest Pacific; initial intensity: Tropical Storm.
It peaked at Tropical Storm intensity with max winds of 18 m/s (~65 km/h) and a minimum central pressure of 1000hPa, recorded at 2023-12-17 08:00:00.
2023-12-18 20:00:00 After, Typhoon Jelawat gradually weakened and was numbered off on 2023-12-18 20:00:00 was numbered off; its lifecycle recorded 11 track points.
The short history of the 17th Typhoon “Jelawat” in 2023, the observation data coverage period of December 17, 2023 08:00 to December 18, 20:00. From the path coordinate sequence analysis, the Typhoon overall presented toward WN, then turned to W line and slightly slashed toward NW’s Trend. The initial phase (17 December 08:00 to 14:00) , the system position at lat 7.5 degrees near, the length slowly moved from 128.6°E to 128.1°E, Moving speed relatively slower.
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.
During the entire period of the observation window, its peak intensity is only at Tropical Storm level, the maximum continuous wind speed isined at 18m/s, the central minimum air pressure is 1000hPa. From the 17th 08:00 to the 18th 11:00, the intensity remains highly stable, wind speed and air pressure have not changed significantly. however, from the 18th 14:00, the system Intensity begins to weaken, decline to Nameless, max wind drops to 16m/s, Pressure rises to 1002hPa, until the end of the observation continues to maintain this Intensity, indicating its structural loose, lack of energy support for further development.
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 的最低气压 (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热带气旋过程.
