摘要
选取中国地壳运动监测网2000~2004年数据,使用高精度定位定轨软件GAMIT处理,得到各测站可降水量时间序列,继而采用经验模态分解并提取各站可降水量变化趋势。对处于不同气候类型区域的GPS站可降水量进行分析,结果显示,处于热带季风气候、亚热带季风气候、温带大陆性气候和青藏高原高寒气候等区域的GPS站的可降水量变化趋势为先升后降;处于温带季风气候区域的GPS站点的可降水量变化为先降后升。
A method of empirical mode decomposition was used during 2000 - 2004 from GPS data of Crustal Movement Observation to processe precipitable water vapor time series Network of China(CMONOC) and change trend of precipitable water vapor at every GPS station was obtained. The result of classification and comparison for the change trend indicates that the change trend in tropical monsoon climate zone, monsoon climate of subtropical zone, temperate continental climate zone and alpine climate zone is first up and then down;the change trend in temperate monsoon climate zone is first down and then up.
