中文摘要 | 本文主要用統計方法和皆析法探討1993至25004年臺灣地區21個中央氣象局所屬氣象站校正後日射量資料。研究發現月平均日謝量值最大出現在7月,最小值出現在12月。臺灣地區每月的日射量分布型態皆屬於右偏,其中5月候最接近常態分布,而6月份最不接近常態分布。至於年平均日射量在空間上的分布有由北門南遞增的趨勢,最高值出現在臺東,最低值出現在基隆。在調和分析方面,研究發現第1和第12調和量對原始資料最具影響性,其中第1調和量與太陽黑子週期有關,北部地區受第1調和量的影響較小,而嘉義受其影響最大。第12調和量與季節變化有關,北部地區受第12調和量的影響較大,而恆春受其影響較小,其最大值集中出現在6月之間。 |
英文摘要 | Solar radiation is the most important data for the design of solar energy system. To make full use of solar energy, we must have a whole understanding of daily solar radiation characteristics. This study implements statistical and harmonic methods to analyze the calibrated solar radiation data of twenty-one weather stations in Taiwan. the results indicate that the maximum value of monthly mean daily solar radiation falls in July, and its corresponding minimum value falls in December. The distribution types of daily solar radiation in different months are all positively skewed distribution. The data in May are closest to be normally distributed, but that in June are farthest from being normally distributed. The annual mean daily solar radiation has an increasing trend from north to south, with the maximum in Taitung and the minimum in Keelung. With regards to harmonic analysis, the study also finds the first and the twelfth harmonics are almost dominant to the trend of the original data. The first harmonic is related to sunspot cycle. It affects Chiayi most and northern area less. The twelfth harmonic is related to seasonal change. It influences northern area more than Hengchun. Its maximum value occurs mostly in June. |
