大气潮对重力固体潮的影响及其改正方法

THE ATMOSPHERIC TIDE INFLUENCE ON GRAVITY TIDE AND ITS CORRECTING METHODS

本文从数据处理的角度探讨和研究了大气潮对重力固体潮之影响的分析及其改正的实用方法——综合分析法(FCM)。试算结果表明该法简单易行,基本上能反映出其影响的客观情况。昆明地区大气潮对重力固体潮潮汐因子的影响——大气潮影响因子△δ的最大量级可达:△δ_(?)=220.3％,△δ_(?)=1.4％,其它波群处约为0.1～0.7％。

A practical--synthetical method (named FCM)is researched and discussed from data processing point of view for analysing and correcting the atmospheric tide influence on gravity tide. The results tested show the method is simple and easy to be carried out, and it basically reflects the practical situation of the influence. The maximum order of atmospheric tide influence on gravity tide factor--the atmospheric tide influence factor △δ in kunming area is up to: △δs_1=220.3%, △δs_2=1.4%, and those of other wave groups is approximately 0.1% to 0.7%.
