• 中文摘要： 本文從天氣之熵所演伸之情報比觀點來探討本省各地氣侯之類似程度，經選擇13個測站，以1950~1979計30年之逐月份氣候要素如平均最高氣溫、平均最低氣溫、日照率、相對濕度、雨日及雨量等為據，加以分析結果，可以客觀的看出本省各地氣候之類似程度，就單項氣侯要素而言，地理位置相近者，其類似性未必最大，反之亦然，如臺中與新竹、臺南與高雄之平均最高氣溫類似性小，臺北與臺南之平均最低氣溫類似性大，宜蘭與臺南、高雄之相對濕度類似性亦大。但綜合各項氣候要素而論，則明顯呈現出地理位置相近者氣候之類似性較大。若以各地氣候類似程度為據，則本省除去中央山地以外，其氣候區域可概分為北部、西部、西南部、東北部、東南部與南部等六區。
• 英文摘要： The present paper deals with the similarityof local climate Taiwan from the view pointof information ratio that based on the entropyof weather. Thirteen meteorological observa-tories were selected from 1940 to 1979, themonthly data of climatical element such asmean maximum and minimum air tempera-ture, relative humidity, duration of sunshine,number of rainy days and amount of rainfallwere adopted. The results are summarizedas follows: 1. If the information ratio based on all cli- matical elements, the similarity of climate always show the largest value between two near location, but this phenomenon will change into not exactly if the infor- mation ratio based on one item of clima- tical element only.2. The climatical division in Taiwan except the central mountain area can be divide to six regions as North, West, South- west, North-east, South-east and South by the information ratio.
