温泉水平摆与垂直摆观测资料对比分析

COMPARATIVE ANALYSIS OF OBSERVATIONAL DATA FROM HORIZONTAL AND VERTICAL PENDULUMS IN WENQUAN

为研究同一台站,同一物理量,以不同观测方式获取资料的一致性,选取温泉老台水平摆和垂直摆为研究对象,研究在不同频段观测数据的一致性与干扰异常的响应特征。分析结果表明:温泉水平摆与垂直摆观测数据稳定、精度高,固体潮记录清晰,在半日波、日波频段相同分向具有较强的一致性;分钟值至潮汐频段,温泉水平摆与垂直摆观测数据一致性较差,观测数据主要包含的是自身属性信息;年周期频段,温泉水平摆、垂直摆在EW向两者相位差约41天;NS向相位差约14天,相位均滞后于气温。在考虑相位滞后的情况下,温泉水平摆与垂直摆观测一致性较好,均与气温线性相关,故气温是温泉水平摆、垂直摆年周期频段的主要影响因素。

In order to study the consistency of data obtained by different observation methods at the same station and the same physical quantity,the horizontal pendulum and vertical pendulum of the hot spring old station are selected as the research objects to study the consistency of observation data and the response characteristics of interference anomalies in different frequency bands.The analysis results show that the observation data of horizontal pendulum and vertical pendulum of hot spring are stable and accurate,the solid tide record is clear,and there is strong consistency in the same direction of semi-diurnal wave and daily wave frequency bands.From the minute value to the tidal frequency band,the observation data of the horizontal pendulum and the vertical pendulum of the hot spring are inconsistent,and the observation data mainly contain their own attribute information;in the annual periodic frequency band,the phase difference between the horizontal pendulum and the vertical pendulum in the EW direction is about 41 days.The phase difference in NS direction is about 14 days,and the phase lags behind the temperature.Considering the phase lag,the horizontal pendulum and vertical pendulum observations of hot springs are in good agreement,and both are linearly related to the temperature.Therefore,the temperature is the main influencing factor of the annual periodic frequency band of the horizontal pendulum and vertical pendulum of hot springs.
