本文探讨了根据合成风原理,利用单站测风资料进行海陆风分析的理论和具体方法。分别统计分析了石岛、龙口、乳山口三海洋站的风资料,得出该三地区海陆风强度和风向的日逐时变化规律,并分析其成因。本方法较传统习用的天气图法之优越之处在于:可仅使用单站测风资料分析海陆风,尤其可方便地分离出日逐时的海陆风强度及风向的变化。如利用此方法将某沿海邻近各站的测风资料进行分别统计和综合分析,还可得出该地区海陆风环流的作用范围,这对于分析预报局部地区天气是很有用处的。
In this paper, we discuss the theory and the concrete method of analyzing the sea-land breeze by using the single wind data. The wind data of the three marine stations of Shidao, Longkou and Rushankou are statistically analyzed, and the daily hourly-time variation law of the strength and direction of the sea-land breeze in the three regions is obtained and analyzed. This method is superior to the conventional weather chart method in that it can be used to analyze the land-sea breeze by using only the single-station wind measurement data, and in particular, it is convenient to separate the day-to-day changes in the strength of the sea breeze and the wind direction. Such as the use of this method will be a coastal statistical analysis of the wind and the adjacent stations and comprehensive analysis of the region can also be concluded that the scope of land and sea breeze circulation, which is useful for the analysis and forecast of weather in some areas.
