中文摘要 | 本研究是以1950至1995年本省十個氣象站的資料,分析溫度的變化,包括平均氣溫、平均最高溫、平均最低溫及日溫差在過去45年間的改變趨勢,並針對影響日溫差的因子加以探討。結果顯示除恆春外,平均氣溫在9個測站資料,皆呈上昇趨勢,也就是全省皆呈暖化現象,其中以臺北上昇0.73℃最高。平均最高溫除宜蘭略微上昇0.35℃外,其餘皆下降,下降幅度臺南為1.03℃,其餘皆在1℃以內。平均最低溫在10個測站皆呈增加,尤其以臺北、阿里山及臺南三地增加幅度超過1℃以上。日溫差則除宜蘭及臺東些微增加外,其餘皆明顯下降。另依每月的變化趨勢而言,日溫差以冬天(12月-2月)下降較多,夏季(6月-8月)下降最少。而臺北夏季平均氣溫的升高主要來自於平均最低溫的提高,而非最高溫的增加。平均雲量與平均最高溫、日溫差呈明顯負相關。另由阿里山地區分析為例發現,雖然45年來平均雲量變化不大,但不同雲量的天數明顯改變,全年中疏雲日數取代裂雲及密雲日數,而晴空日數大致不變。 |
英文摘要 | This research is to analyze the trends on mean temperature, mean maximum temperature, mean minimum temperature and diurnal differential temperature of 10 weather stations in Taiwan over the past 45 years (1950-1995). The factors affecting diurnal differential temperature are also described in the paper. The current records reveals a increase in mean temperature for most areas except Hengchun. This seems to be a warming phenomenon for the whole is land area, and the largest rise of temperature (0.73°C) appeared in Taipei area. The mean maxium temperature has risen about 0.35°C at Ilan, but decreased at other areas. The decreasing ranges are 1.03°C at Tainan and less than 1°C at the other areas. The mean minimum temperature ahs increased for all stations, especially Taipei, Alishan, and Tainan. The increasing ranges of the three stations are more than 1°C. There is a significant decline in diurnal differential temperature for most areas except Ilan and Taitung, In monthly changes, the decrease of diurnal differential temperature is larger winter (from December of February) than in summer (from June to Augest). At Taipei, the increase of mean temperature in summer may be resulted from the elevated mean minimum temperature, not from the mean maximum temperature. The mean cloudness was significantly negatively correlated to mean maximum temperature and to diurnal differential temperature. At Alishan area, the mean cloudness remained const ant over the past 45 years, but the number of cloud days have changed significantly. During the whole years, the number of scattered and broken days increased, overcast days decreased and clear days remained constant. |
