Typhoon Bolaven trajectory analysis
Path and Moving Characteristics
Typhoon Bolaven (201215) 的生命史长达11天, 整体呈现典型的NW行后转 toward NE的抛物线型路径. formed初期, 系统位 at 关岛以E海域 (14.2°N, 142.2°E) , 稳定 toward NW. 在8月23日至25日期间, 随着纬度N抬至24°N附近, 其经度从136.4°E快速W进至130.9°E, 显示出一段显著的W行加速过程.
The track's key turning point occurred around August 27. When the center reached approximately 30°N, 126°E, its direction of movement changed markedly from northwest to north and then toward northeast. This turn was accompanied by a rapid increase in latitude, rising sharply from 36.5°N on August 28 to 53.7°N on August 30 before the system dissipated in the high-latitude seas. This large-scale curvature was typical of changes in the steering flow along the edge of the subtropical high.
Intensity evolution and historical comparison
该Typhoon 经历了完整的“增强-巅峰-减弱”生命周期. 初始阶段为Tropical Depression (15m/s) , 随后快速加强, at 8月25日达到巅峰状态, 确立为Super Typhoon, 中心最低气压降至920hPa, max wind 达55m/s. 值得注意的是, 在接近land前, intensity 出现波动, 8月26日维持Severe Typhoon级别 (50m/s) , 但Go to 黄海后迅速减弱. 8月28日先后Landfall黄Hainan道和朝鲜平安地区时, 已降级为Severe Tropical Storm, wind speed分别为31m/s和28m/s左右, 显示出海陆摩擦及高纬度冷海水对其结构的破坏作用.
Compared with previous storms of the same name, Bolaven in 2012 reached a higher intensity. Its peak pressure of 920 hPa was less extreme than the 2020 storm (900 hPa), but much stronger than the same-named systems in 2005 (975 hPa), 2000 (980 hPa), and 2018 (1000 hPa). The 2018 storm reached only tropical storm intensity, while the 2012 storm completed the full progression from tropical depression to super typhoon and maintained typhoon-strength intensity for an extended period in the mid- to high-latitude region, weakening into a tropical depression only above 50°N. This demonstrated strong longevity and energy retention.
