Typhoon Bess (197809) 的生命史始 at Northwest PacificW部海域, 整体呈现稳定的SW toward MovingTrend. 从1978年8月8日00:00 formed at 22.5°N, 122°E附近开始, 该系统持续 toward SW direction行进, 穿越巴士海峡W侧Go to S海N部. 在整个生命周期内, 其The latitude从22.5°N逐渐降低至17.6°N, During从122°EW移至105°E, 未出现明显的转 toward 或回旋动作. 值得注意的是, 该Typhoon 全程无Landfall记录, 始终在海上活动, 最终 at 8月12日00:00在17.6°N, 105°E附近减弱消散. track points分布显示, 其在S海N部的Moving速度相对均匀, 主要受大尺度引导气流影响, 保持了较为线性的SW路径.
The initial phase is Nameless, max windined between 7-12m/s. With the system toward W deep in the sea, the environmental conditions slightly improved, wind speed gradually increased to 15-17m/s between August 10 and 11th. The peak time appeared on August 11th at 12:00, at this time the center position at 17.7°N, 107.4°E, level upgraded to Tropical Storm, max wind reached 20m/s. However, this peak state is extremely short, only afterining about 6h, the system is re-leveled to Nameless, wind speed returned to 17m/s, and in the following 12h further weakened to 12m/s. This 'weak life disappears' and peak intensity is lower characteristic, indicating that it can receive insufficient thermal energy or strong
The data show that in 1996, 1979 and 1974 Bess reached the typhoon or severe typhoon level, while in 1982 Bess also developed to Super Typhoon. in comparison, in 1978 Bess only for Tropical Storm level, max wind 20m/s very low at other years of the same name Typhoon typical Intensity. This reflects that despite the total enjoying the same title, different years of Bess in the formed background, sea temperature conditions and atmospheric flow configuration there are huge differences, the 1978 system is at typical weak tropical cyclone.
