南极长城站近海潮汐特征的初步分析

A PRELIMINARY ANALYSIS AND STUDY OF THE TIDAL CHARACTERISTICS OFF THE GREAT WALL STATION OF ANTARCTICA

本文对1987年1月5日至3月7日在南极长城站海湾获取的潮位观测记录进行了分析。结果表明:这里的潮汐属于不正规半日潮,最大可能潮差按公式2(1.29H_(M2)+1.23H_(s2)+H_(k1)+H_(01))计算为2.944m。对其近海的潮波,以及潮位对气压变化的响应做了初步分析。

In this paper, the records of the tidal observation obtained in the Great Wall Station Bay during the period from 5 January～7 March 1987 are analyzed. The results show that the Bay has the features of non-regular, semidiurnal tides and the maximum probable tidal range is 2.944m based on the calculation with the formula: 2(1.29HM_2+1.23Hs_2+Hk_1+Ho_1). Meanwhile, the tidal waves off the Bay and the responses of the water level to the variations of air-pressure are analysed and studied preliminarily.
