摘要：

利用上海沿海14個站點2012-2019年的觀測資料，分析了2 min平均風速和極大風速的關(guān)系，對沿海站點極大風速預報方程進行了細化和完善。結(jié)果表明：2 min平均風速與極大風速具有近似線性的關(guān)系；2 min平均風速和極大風速的關(guān)系不是均一分布，各站點極大風速回歸方程的回歸系數(shù)從沿岸到近海基本呈遞減趨勢；對4級以上的平均風，各站點極大風速回歸方程的回歸系數(shù)隨風級增大基本保持不變；獨立樣本檢驗結(jié)果表明，建立的各站點極大風速回歸方程能夠較好地用來估計各站點的極大風速；臺風影響上海沿海期間與全時間段的極大風速回歸方程基本一致。

Based on the observation data of 14 coastal stations in Shanghai from 2012 to 2019, the relationship between 2-minute average wind speed and the maximum wind speed is analyzed, and the maximum wind speed prediction equation of coastal stations is refined and improved. The results show that there is an approximate linear relationship between the 2-minute average wind speed and the maximum wind speed. However, the relationship between the 2-minute average wind speed and the maximum wind speed reveals inhomogeneous distribution, and the regression coefficient of the regression equation of the maximum wind speed at each station basically decreases from the coastal to the offshore area. For the average wind over category 4, the regression coefficient of the regression equation of the maximum wind speed at each station is basically unchanged with the increase of wind category. Moreover, the results of independent sample validation show that the established regression equation of the maximum wind speed can be used to estimate the maximum wind speed of each station. The regression equation of the maximum wind speed during the period of typhoons affecting Shanghai coast is basically consistent with that of modeling period.
