针对实测水位资料中存在余水位的问题,进行气象因素中风与余水位的相关性以及风对余水位的延迟效应的研究。用统计分析法对青岛站数据分析得出,偏北风对减水贡献较大,偏南风对增水贡献较大;进一步对比分析得出:风对余水位的影响有一定的延迟性,延迟时间的长短与风速的大小成线性关系,风速越大延迟时间越短,造成的余水位变化幅度越大。通过本文分析可以为进一步研究余水位的特性、改进水位预报精度提供一定的参考。 Aiming at the problem of residual water level in measured water level data, the correlation between meteorological stroke and residual water level and the delay effect of wind on residual water level were studied. Statistical analysis of Qingdao station data shows that the northerly wind contributes more to the water reduction and the south southerly wind contributes more to the water increase. Further comparative analysis shows that the wind has a certain delay on the impact of the remaining water level, The length of the delay time is linear with the wind speed. The larger the wind speed, the shorter the delay time and the greater the change of the remaining water level. Through the analysis of this paper, we can provide some reference for further research on the characteristics of the remaining water level and the improvement of water level forecasting accuracy.
