Abstract:The article analyzed the spatiotemporal variation characteristics of the low-level environmental wind field in Daishan County Meteorological Station from 2012 to 2023 using data from 26 strong winds.According to statistics,southern winds prevail in Daishan County from April to August,and northern winds prevail from September to March of the following year.The process of winter monsoon to summer monsoon is slow,while the process of summer monsoon to winter monsoon is fast.6-8 level strong winds occur most frequently in autumn and winter,and least frequently in summer.Strong winds above level 9 mainly occur from July to October.On both sides of the Daishan sea area,75% of the hourly winds exceed 3-4 levels,and 75% of the hourly winds do not exceed 7 levels,with an average wind speed of 4-5 levels.The wind speed in the southern and western parts of Daishan County is smaller compared to the wind speed in the eastern and northern parts.In addition,in the eastern and western waters of Daishan Island,small winds mainly occur in the afternoon during winter and spring,and in the morning during summer and autumn.In the southern waters of Daishan Island,small winds mainly occur in the morning during spring,from morning to afternoon during summer,morning and night during autumn,and night during winter;In the northern waters of Daishan Island,the main occurrence of moderate winds in spring,summer,and autumn is in the morning,while in winter it is at night.
