使用间隔气象数据的余水位分析

Analysis of Residual Water Level Using Interval Meteorological Data

余水位是潮汐预报中的"报不准"部分。在现有条件下,许多验潮站在对水位数据进行连续采集的同时,对气象数据还使用间隔时间采集的方式(若干小时采集一次)。使用间隔气象数据,按风向不同对气象数据、余水位数据进行分组,对风与余水位关系进行定性分析,对风-压与余水位关系进行拟合分析,并结合实例,对方法进行说明和检视。

The residual water level is the error in tide forecasting. Under current conditions,while water level data is acquired continuously,tide stations are collecting interval meteorological data（ one sample every several hours）. Using interval meteorological data,meteorological data and residual water level data are sorted into different groups according to the wind direction,the qualitative analysis of the relationship between wind and the residual water level is conducted,as well as the fitting analysis of the relationship between wind and air-pressure and residual water level,and an example is given to showhowthe mentioned method works.
