科學圖說 Introduction
每年10月至次年4月,東北季風翻過中央山脈於恆春半島降下,形成強勁的落山風,是舉世罕有的地理現象。風,沒有氣味、沒有顏色、來無影去無蹤,而它形成的方式,有人為的機械動力(如電扇),也會由自然的高低氣壓形成,但我們卻無法留下它。如今我趁著落山風季節,以拍照來記錄它走過的痕跡,有旋轉、有直線、有交錯。
From October to April each year, northeast monsoon winds flow from the Central Mountain Range and descend onto the Hengchun Peninsula, forming strong katabatic winds, which is a rare geographical phenomenon. Wind has no odor or color and sometimes comes and goes without a trace. Turbines are powered by such natural pressure differences. Yet, we cannot hold onto the wind. I photographed the tracks left behind by katabatic winds, including swirls, straight lines, and staggered patterns.
