臺大實驗林溪頭營林區夏季降雨之長期趨勢

The Long Term Trend of Summer Precipitation at Sitou Tract Experimental Forest of N.T.U.

摘要


本研究嘗試利用統計語言軟體R的模組rclimdex分析氣候變遷指數,由溪頭長期降雨資料來探討氣候變遷之影響。從溪頭降雨強度指數(SDII)、降雨量超過10mm、20mm及25mm的日數降雨指數(R10mm、R20mm、R25mm)及年降雨量指數(PRCPTOT)均是呈現些微下降的趨勢。而連續乾燥日數(CDD)是呈現微幅上昇的趨勢,至於連續降雨日數的CWD指數有明顯下降的幅度,上述降雨指數的趨勢似乎意味著溪頭在未來會越來越乾燥。

並列摘要


This study presents the long-term trend of precipitation at Sitou tract in the experimental forest of National Taiwan University. Eleven climate change indices from the 46-year rainfall record were analyzed by using rclimdex of R language in order to diagnose the long-term trned related to climate change. We found that consecutive dry days (CDD) index ascended slowly with time, while consecutive wet days (CWD) index was significantly declined. These two indices revealed the drier trend at Sitou.
