Typhoon Wendy (199909) 的生命史始 at 1999年8月29日06时, formedPosition位 at lat 11.5°N, 133.4°附近海域. 在初始阶段, 该系统表现为典型的Nameless形态, Moving速度相对缓慢且路径较为平直. 从8月29日至8月31日期间, Typhoon 中心主要维持在W toward 或WNW, The latitude变化微小, During从133.4°E逐步W移至127.5°E, 显示出受低层引导气流稳定控制的特征.
From September 1 at 06 pm, the Typhoon Moving direction shifted to NW toward, and the shift speed significantly accelerated. especially in September 1 at 18 to September 2 at 06:00 this 12h, the latitude jumped rapidly from 14.9°N to 18.2°N, the length synchronized W shift, indicating that the system was led by a stronger steering flow, and began to accelerate toward continental direction.
在Intensity演变方面, Wendy经历了从Nameless到Tropical Storm, 再回归Nameless的过程. 系统在 formed初期至9月2日18时前, max wind 维持在7m/s至12m/s之间, 处 at Nameless等级. 9月2日18时, wind speed增至17m/s, 显示加强Trend. 直至9月3日06时, 系统达到peak intensity, 定性为Tropical Storm, max wind 录得20m/s. 此后Intensity并未持续增强, 而是在9月3日18时维持峰值后, at 9月4日06时迅速 weakened into 10m/s的Nameless, 生命史结束.
In contrast, in 1999, Wendy only reached the 'Tropical Storm' intensity with max winds of 20m/s, belonging to the weaker tropical cyclone.
