摘要

本文使用1981-1999年1月及7月之中央氣象局高雄測站所觀測峰向風速資料，嘗試分析高雄市之風向風速日變化及季節變化。結果發現去除大尺度環流之影響可以改變風向之轉變，由於海陸風屬局部環流，與大尺度環流比起來所佔比例較低，這也說明大尺度環流之影響不容易移除，期待本文可建一單站分析方法，進而研究局部地區海陸風之變化。

This study examined wind data from Kaohsiung station of Central Weather )f January and July of 1981-1999. The objective was to analyze the diurnal cycle of the wind as well as the seasonal variation. Results show that removing the seasonal cycle could change the diurnal wind vectors dramatically. Due to a smaller portion occupied by the diurnal cycle, it would be difficult to totaIly remove the seasonal cycle. It is believed that this study could be useful to establish a single station analysis in order to study the local land/sea breeze.
