台风预报实践表明,预报中产生的误差,虽是由多种因素造成,但是。对西北太平洋付高短期振荡的趋势估计其误差,却是一个重要的因素。为此,分析西北太平洋付高的振荡过程,对提高台风路径的短期测报,有重要意义。 引起西北太平洋付高振荡的原因是复杂的。我们根据资料分析,初步认为 The practice of typhoon forecast shows that the errors in forecasting are caused by many factors. Estimating the error in the trend of paying high and short-term oscillations in the western North Pacific is an important factor. Therefore, it is of great significance to analyze the process of oscillating high in the western North Pacific to improve the typhoon track. The reason for the high oscillations in the western North Pacific is complicated. According to the data analysis, we think initially
