用同相叠加方法识别定点形变数据中的降雨影响

Distinguishing the Rainfall Disturbing Pattern in Crustal Deformation Recording by In-Phase Stack of Data

分别以昆明台、云龙台为例,用数据同相位叠加的方法分别对形变数据中的典型图像及其对应时段的降雨数据进行叠加,以判断典型图像是否与降雨有关。结果表明,昆明台形变观测中多次出现的同步转折为降雨影响;而云龙台的转折现象则与降雨无关,其来源及属性需要进一步研究。

This paper is concerned with distinguishing rainfall disturbance from tectonic deformation. We use an in-phase stack technique on crustal deformation data and corresponding rainfall data in Kunming and Yunlong stations to judge whether the patterns repeated in crustal deformation data are related with rainfall. We argue that the patterns in Kunming station support rainfall disturbance but that the patterns in Yunlong station do not.
