Typhoon Stella, international code 199805, international name STELLA, 1998 Northwest Pacific typhoon. Formed: 1998-09-10 00:00:00, ended: 1998-09-16 18:00:00. Peak intensity: Typhoon , minimum central pressure: 970 hPa, max wind: 33m/s.
Typhoon Stella at 1998-09-10 00:00:00 at 17°N, 149.6°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 33 m/s (~119 km/h) and a minimum central pressure of 970hPa, recorded at 1998-09-14 18:00:00.
1998-09-16 18:00:00 After, Typhoon Stella gradually weakened and was numbered off on 1998-09-16 18:00:00 was numbered off; its lifecycle recorded 28 track points.
Typhoon Stella (199805) 的生命周期始 at Northwest Pacific远洋海域, 整体路径呈现典型的“NW—NE”抛物线型Moving特征. formed初期 (9月10日至12日) , 系统位 at lat 17°附近, lng 145°至150°之间, 受副热带高压S侧引导气流影响, 主要维持 toward WN direction缓慢Moving, The latitude变化不大, During持续W进. 9月13日起, 随着系统 toward N推进至lat 21°以N, Moving direction逐渐转为NW toward , 移速有所加快.
The key shift toward point appeared in the early morning to midday period of September 15th. At this time the typhoon center was at lat 28.1° to 32.1° N, 136.4° to 136.9° nearby. The data showed that during the period of September 15th 00:00 to 12:00, the latitude rapidly jumped from 28.1° N to 32.1° N, while the length only microscope E moved 0.5°, indicating that the system was drawn here by the pre-air flow of the W belt, beginning to occur a significant path shift. Since then, typhoon accelerated toward NE, and finally at September 16th 18:00 reached lat 46° N, 154° high latitude sea area and ended observations.
Stella's Intensity evolution has undergone a complete development process from Nameless to Typhoon, and hasined a higher Intensity in the high latitudes.Initial phase (September 10 to 12), the system has longined in the Nameless level, max wind wandering between 10-12m/s, development is relatively slow.On September 13, after 00:00, wind speed increased to 15m/s, and at the same day at 12:00 intensified into Tropical Storm (23m/s).
On September 15, 00:00, the system reached peak intensity, upgraded to Typhoon, max wind recorded 33m/s. It is worth noting that the Typhoonined a longer time at peak intensity, from September 15, 00:00 to September 16, 00:00 within 24h, max wind stability remained at 33m/s, even when the latitude rose significantly to 36.3°N and did not immediately weaken, showing strong structural stability. until September 16, 12:00, when the center moved to 43.6° high latitude cold water area, the intensity did not fall back to Severe Tropical Storm (30m/s) , and at the end of lifeined this intensity until dispersed.
