一、前言连云港是我国重点建设港口之一,为了扩建港口的需要,曾在34°52′48″N、119°42′24″E处投放了“波浪骑士”测波仪。进行波要素的连续观测。我们在整理观测资料过程中,发现波浪记录中有明显的波群现象,即在波列中高度较大的波浪连续几个成群地出现。通常把海面上的不规则波看成是随机过程,并不考虑变量出现的先后次序。也就是 I. Preface Lianyungang is one of China’s key construction ports. In order to expand the port’s needs, the Wave Knight telemeter was launched at 34 ° 52’48 “N, 119 ° 42’24” E. Continuous observation of wave elements. During the process of sorting out the observed data, we found that there are obvious wave swarms in the wave records, that is, a few waves in a wave column appear successively in large numbers. Irregular waves on the sea are usually regarded as random processes, regardless of the order in which the variables appear. That is
