Typhoon Brenda, international code 198903, international name BRENDA, 1989 Northwest Pacific typhoon. Formed: 1989-05-14 00:00:00, ended: 1989-05-21 00:00:00. Peak intensity: Typhoon , minimum central pressure: 970 hPa, max wind: 38m/s.
Typhoon Brenda at 1989-05-14 00:00:00 at 6.7°N, 138.3°E over the Northwest Pacific; initial intensity: Nameless.
It peaked at Typhoon intensity with max winds of 38 m/s (~137 km/h) and a minimum central pressure of 970hPa, recorded at 1989-05-19 18:00:00.
Typhoon Brenda gradually weakened and was numbered off on 1989-05-21 00:00:00 was numbered off; its lifecycle recorded 29 track points.
Typhoon Brenda (198903) 的生命史始 at Northwest Pacific低The latitude海域, 整体路径呈现稳定的NW toward MovingTrend. 从1989年5月14日00时在 (6.7°N, 138.3°E) formed初起, 系统持续 toward NW direction推进, 横跨Philippines以E洋面并Go to S海NE部. 在整个生命周期内, 该Typhoon 未出现明显的路径转折或回旋现象, Moving direction具有较高的一致性.
By coordinate sequence analysis, its length shifted from 138.3°E rapidly to 111.3°E, the latitude increased from 6.7°NN to 22.6°N, indicating that it was significantly affected by the sub-tropical high-pressure S-side guided air flow. It is worth noting that the system has no landfall record throughout, is always active at sea, and eventually at 21 May at 00 am in the S-Sea N area weakened dispersion.
Brenda的Intensity演变经历了典型的“增强-波动-再增强-迅速减弱”过程. 初期作为Nameless缓慢发展, at 5月16日12时 intensified into Tropical Storm. 随后在5月17日至18日期间, intensity 出现短暂波动, 曾由Severe Tropical Storm回落至Nameless级别, 反映出当时环境场可能存在垂直风切变或干空气侵入等不利因素. 然而, Go to S海后系统重新整合, at 5月19日12时再次发展为Typhoon , 并在5月20日00时达到peak intensity, max wind 录得38m/s.
巅峰维持Time较短, 仅约12h后, 随着The latitude继续N抬及可能的海面Temperature变化, 系统迅速衰减, 至5月21日00时已 weakened into Nameless. 与同名History相比, 1985年的Brenda (198519) peaked at Severe Typhoon级别, 显然强 at 1989年的这一例. 198903号Typhoon 虽达到Typhoon 级标准, 但其Max Wind38m/s与Severe Typhoon门槛仍有差距, 且生命史中期的Intensity反复显示出其结构稳定性不如1985年同类系统. 总体而言, 这是一次中等Intensity, 路径规整但未Landfall的海洋性Typhoon 过程.
