山东半岛月湖的潮汐水位特征

１９９８年１１－１２月和１９９９年８－９月在月湖用Ａanderaa WLR7/８型自记式潮位仪各取得２９d的潮位资料，对潮位数据进行了调和分析，并进行了对比，，结果表明，月湖潮汐类型属于以半日潮为主的混合潮，浅水分潮较为显著；冬季平均水位比夏季低０．３４m，冬季水位的非潮汐组分比夏季发育，冬季主要分潮相位比夏季延迟，这些差异可能是天气因素造成的。

CHARACTERISTICS OF SWAN LAKE TIDAL WATER LEVELS, SHANDONG PENINSULA

Two tidal water level data sets, each with a length of 29 days, were obtained from the Swan lake using Aanderaa self recording tide gauges (Model WLR 8 and WLR 7) during November December 1998 and August September 1999. Harmonic analysis of the data was undertaken with the method developed by the Proudman Oceanographic Laboratory. The results show that the monthly average water level in winter is 0.34 m lower than in summer. The tides in the Swan Lake are of a mixed type dominated by semidiurnal tides, and there exist phase lags in the major constituents between winter and summer. Furthermore, shallow water overtides are significant in comparison with the major constituents, and non tidal constituents (caused by storms etc.) in winter are more remarked than in summer. The seasonal variations in the tides described above may be caused by monsoon factors.
