上个世纪全球海平面上升了大约20厘米和3毫米
平均每年。海平面上升之后，地区和当地的海平面上升会影响到
直接到达海岸地区。事实是，世界上有这么多人(占人口的23%)，
居住在沿海地区。因此，监测海平面变化和确定
变化的外部因素是需要的。这项研究将分析这一变化。
近五年平均海平面及中国海平面变化的外部因素
巴东市使用永久平均海平面服务(PSMSL)站的数据。
可以计算海平面数据来定义每月的MSL和每年的MSL
之前已通过尖峰错误、丢失数据和移位更正进行了更正。
由T-Tide或Microsoft Excel计算的月度MSL和年MSL
用来分析巴东市的海平面变化。气象数据，包括
降雨量和雨强是确定海平面外部因素所必需的。
变化。采用Linier回归作为分析模型。
结果表明，五年的MSL年化差异不显著
总计+5，8 mm或每年+1，8 mm变化。降雨强度和降水量
不影响海平面的年变化或月变化。MSL、降水和
年末的降雨强度较大。地震和洪水使每天
MSL高于月MSL。
Global sea level rise in the last century was approximately 20 cm with 3 mm
average per year. The rise is followed by regional and local sea level rise that affects
directly to the coast area. The fact is so many people ( ± 23% of people) in the world,
live in coast area. Therefore, monitoring of sea level changes and defining the
external factors of the change are needed. This research will analyze the change of
Mean Sea Level during five years and the external factors of sea level changes in
Padang City by using Permanent Service for Mean Sea Level (PSMSL) Station data.
Sea level data can be calculated to define monthly MSL and annualy MSL that
has been corrected with spike error, missing data, and shifting correction previously.
Monthly MSL and annualy MSL which are calculated by T-Tide or Microsoft Excel
is used to analyze sea level change in Padang City. Meteorology data, consist of
precipitation and rain intensity, are needed to define the external factors of sea level
change. Linier regression is used as the model of analysis.
The result shows that annualy MSL for five years is not significantly different
with +5,8 mm total or +1,8 mm change in per year. Rain intensity and precipitation
do not influence the annualy or monthly sea level change. MSL, precipitation and
rain intensity in the end of the year are higher. Earthquake and flood make the daily
MSL is higher than the monthly MSL.
