Abstract
西元2001年9月，納莉颱風的侵台重創了台北市，同時也使台灣多處地方爆發土石流，災情相當慘重。在颱風發展的過程中，海洋扮演著非常重要的角色，納莉颱風在台灣東北海域逗留時間長，行進速度緩慢，其迂迴的行經路徑正好位於黑潮主流上，期間納莉颱風強度數度變化，這變化與海洋有密不可分的關係，本文利用衛星資料搭配海洋數值模式來描述納莉颱風發展過程中海表面溫度與海表面高度的變化，並探討風場與海流之間的關係。
In September of 2001, heavy rains brought by Typhoon Nari had caused 94 dead and 10 missing in Taiwan. Typhoons mix and cool the upper ocean, as shown here in satellite observations and modeling of the Kuroshio off northeast Taiwan during the passage of Typhoon Nari. On the other hand, the upper ocean provides heat and energy to sustain a slow-moving typhoon, such as Nari. Such air-sea interaction may have important impacts on typhoon simulations and predictions.
