    ( 2 )根據土壤溫濕,採用功率譜分析、 pca分析等方法,分析了兩種典型下墊面土壤溫度的時空分佈特徵及其對土壤水分運動的影響,發現研究區土壤溫度除日和年變外還存在6 30天的不;下墊面的非均勻性及其季節變及溫度梯度變對土壤水分運動有很大影響,冬季溫度梯度變對土壤含水量影響大於夏季溫度梯度對上壤含水量變的影響,且溫度梯度與水分運動方向相反。
  3. Since the suggested method makes a significant improvement in wind speed, it is more suitable for wind field estimation over complex terrain than other methods which only concerns the effect of distance. then we calculate the wind change with evaluation, last we can conclude the wind abase the hilly terrain, we find the wind in westward and center plain is much smaller than other area. while the wind in northward hilly area is much bigger with the hilly arising. the wind of chongqing is the biggest period in spring ( april ), the smallest period in winter ( january ), the wind in summer ( july ) is bigger than its in autumn ( october )

    本文利用重慶及其邊地區的常規氣象站的1951 ? 1980年30年的風速平均,針對復雜地形風速診斷,以地理信息系統為數據處理平臺,根據重慶1 : 25萬dem數據,來獲得重慶市實際復雜地形的高程,提出了一種適合於起伏地形的權重內插方法,通過引入一個表示地形起伏變程度的因子,構造了一種新的權重函數,來處理復雜地形上的風速,通過與只考慮距因素反平內插方法比較發現,本方法更適合在起伏地形條件下使用;然後根據經驗公式在地形上進行計算,得出重慶地區起伏地形下的風速分佈;得出重慶市的西部、中部平原地帶風速較小,而北部山區隨海拔高度升高風速也較大;重慶市風速最大時為四月份,冬季一月份最小,夏季(七月份)大於秋季(十月份) 。
  4. Its interannual variation ' s main period is about 4 ~ 5a and the 7 ~ 8a ' s period exist too ; the interdecadal variation ' s main period of the australian high is about 15a. the interannual variation of australian high ( aah ) has correct correlation with antarctic oscillation and enso, and the enso ' s 4a period has the most important influence on the aah. ( 2 ) when the ah becomes stronger, the members of the whole aamcs are stronger following it. that is to say, in the years that the ah is stronger ( compared to the weak years of ah ) and on the horizontal circulation, the members of aamcs, including the ah, the cross - equator flow ( cef ) between 100 and 160 e, the south china sea south - west monsoom ( ssm ), the south sea monsoon rough, the tropical easily flow, subtropical high ( sh ), the mei - yu front, the mid - latitude effect, become stronger, and their positions are more southward ; in the meridional - right circulation, there are five circulations including classic monsoon meridional - cirle circulation and hadley circulation that become stronger in the strong years of ah than in the weak years of ah
