海氣象預報的方式至今有很多，包含諸多常用的經驗方法，或是數值模式預報等。然而漁民、海上作業員、海上遊憩業者及漁類養殖業者，較常根據蒲福風浪關係表由風級來推算浪級，屬於一種快速的經驗法則應用方式。因此本文旨在根據現場的實測海象資料及中央氣象局漁業氣象預報資料，來探討蒲福風浪關係在台灣海域環境下的適用性。
本文分析對象包含台灣海峽內之新竹海域、北部龍洞海域以及台東外洋海域。本研究取得中央氣象局漁業氣象預報資料與新竹、龍洞及台東外洋浮標的實測資料，首先針對漁業氣象預報中的平均風級與陣風進行比對，發現漁業氣象預報在三個海域會因不同季節而有不同程度的誤差，而風級的預測偏差可能導致浪級的預測不準確。如夏季期間預測風級較易有高估現象，以陣風為例，其最大有高估達88.4%(龍洞海域)；冬季期間預測風級則較容易低於實測風速量測值，以陣風為例，最大有低估達54.8%(台東外洋海域)。因此本文以新竹、龍洞及台東外洋三測站實測資料與傳統蒲福浪級比較。分析結果顯示，當風級大於(等於)3時，實測浪高均小於傳統蒲福風級所對應的浪高，且發現三個海域風浪成長規模皆不同，主要是各海域水深與地理位置的差異，影響該海域的風浪成長。本研究也就各海域分別提出修正之蒲福風浪關係，當使用經驗推算可快速得到更貼近的實際海況，因此本文認為所提出之修正蒲福風浪關係較適用於台灣鄰近海域。

Taiwan’s marine meteorology is rather complicated due to 1) complicated landform around Taiwan sea area, 2) typhoons in summer and autumn seasons, and 3) Kuroshio current that flows from Philippine to Japan via the east of Taiwan sea area. To study the complexity of Taiwan’s marine meteorology, this research analyzed and compared fishery forecasting data released by Central Weather Bureau (CWB), Taiwan and in-situ measurement data retrieved from data buoys at Hsinchu, Longdong, and Taitung open ocean, respectively. The comparison discovered that the forecasting data had a significant difference with the measured data. Furthermore, the analyses of this research disclosed that the measured wave-height was significantly lower than that of Beaufort wind-wave correlation, when the wind scale was higher than (or equal to) Beaufort number 3. Accordingly, in this study, a new modified Beaufort wind-wave correlation based on the regression of in-situ measurement data is proposed as a more applicable reference for ocean workers in Taiwan sea area.
