異常波異常波浪(Freak wave)是海面突然出現大波的現象,前人研究多以理論上推導異常波浪發生的原因。本文試著從實測資料著手,利用小波轉換推算浮標水位時序列。在小波能譜上探討異常波浪發生時候波浪的組成特性。經分析花蓮浮標10年的實測資料數據顯示,異常波浪發生的瞬間譜寬較寬,瞬間總能量最大,但瞬間能譜的最大峰值並不一定產生在異常波浪上。分析小波相位譜得知,異常波浪產生的瞬間,主要的成分波位相相當一致,顯示異常波浪是一種成分波的疊加所形成。
Freak wave is the sea suddenly a big wave phenomenon, with many previous studies theoretically the causes Freak waves. This paper tried to proceed from the measured data, using wavelet transform projections when the water level buoys seriers. Wavelet on the spectrum of Freak wave occurred when the composition of the waves. The analysis of Hualien buoy 10 years the measured data showed Freak waves in a wide-spectrum of the moment, the moment the largest total energy, but the greatest moment of peak energy does not necessarily produce the Freak waves. the phase spectrum that wavelet analysis , Freak waves generated an instant, the main component wave phase fairly consistent, show Freak wave is a component of the wave formed by stacking.
