摘要
对2009年7月22日日全食期间,黄梅固体潮观测台站3种固体潮观测仪器的观测数据进行了分析,发现3种观测数据都存在小幅扰动现象。其中,洞体应变南北分量扰动幅度为27.6×10-10,东西分量幅度为9.52×10-10,水管与宽频带垂直摆北南分量扰动幅度分别为0.88毫秒与1.84毫秒。进一步的分析表明,扰动与气温变化具有较强相关性。
The total solar eclipse took place on July 22, 2009 in Yangtze River basin of China is the most important, the longest total eclipse of this century, that the maximum duration of totality reaches 6 minutes 39 seconds. The Huangmei tide observation station having three sets of tide observation instruments is located in the region. A little disturber was found during the total eclipse. The disturber in the north - south direction of the extensometer is about 27.6 × 10^-10 and in the east-west direction about 9.52 ×10^10. The disturbers in the water tube tihmeter and in the north-south direction of the broadband vertical pendulum tihmeter are about 0. 862 millisecond and 1.84 millisecond respectively. The temperature, pressure and rainfall observation data during the total solar eclipse are considered and it is found that there are the strong correlation between these disturbers and temperature change.
