Typhoon Winona (198901)'s life history began at the Northwest Pacific Ocean Ocean, overall presenting a stable W toward MovingTrend. From January 15, 1989 at 12 a.m. at (20.6°N, 178.7°E) formed to January 22, 00 a.m. at (11.6°N, 120.8°E) dispersed, the system within about 6.5 days of time crossed the vast ocean surface. Route analysis showed that the Typhoon was initially mainly guided by the tropical high-pressure S side E airflow, and remained toward WS. Between January 15 and January 19, the latitude continued to decline from 20.6°N to 14°N, the length drastically shifted from 178.7°EW to 140°E, Moving faster and flat path, with no
在Intensity变化方面, Winona经历了“维持-增强-减弱”的典型过程. formed初期至1月18日中午, 系统长期维持Tropical Storm等级, wind speed稳定在20m/s. 1月18日12时, 随着中心附近Max Wind增至25m/s, 系统升级为Severe Tropical Storm, 并 at 次日00时达到peak intensity, max wind 录得28m/s, 随后在1月19日12时前维持该Intensity. 自1月20日00时起, 系统迅速 weakened into Tropical Storm, 并在12h内进一步降级为Nameless, wind speed从20m/s骤降至15m/s, 直至消散前降至10m/s.
与历届同名Typhoon 相比, 1989年Winona的 peak intensity is Severe Tropical Storm (28m/s) . 相较 at 1990年Winona (巅峰Typhoon ) 和1993年Winona (巅峰Tropical Storm) , 其Intensity处 at 中等水平; 与1985年及1982年的同名Typhoon (均为Severe Tropical Storm) 相比, 巅峰等级一致. 值得注意的是, 作为1989年的首个codeTyphoon , 其在1月份即达到Severe Tropical Storm级别, 显示出早期季节Northwest Pacific海域仍具备支持热带气旋发展的热力条件.
