Sample ' s analyses and tests in laboratory, this thesis makes a detailed research on holocene deposits characteristics of mu us desert, especially on characteristics of grain size composition, which break through previous description of determining the nature and gain a series of number indexes. at the same time, this thesis has also researched arenaceous source on every part of mu us. firstly mu us desert ' s forming process is deeply influenced by the east asian monsoon, the grain size gradually becomes smaller, while the magnetic susceptibility becomes larger from northwest to southeast this phenomenon not only appears on the surface of mu us, but also obviously reflects on the same layer of different places
根據大量野外詳細考察和室內樣品分析與測試，本文對毛烏素沙地全新世地層沉積特徵做了細致的探討，尤其對區域地層的粒度組成特徵做了進一步的研究，突破了以往的定性描述，得出了一系列量化指標；結合野外的考察工作，對其不同地區的沙質來源做了詳細分析，主要得出以下結論： 1 、毛烏素沙地形成過程深受東亞季風影響，粒度自西北向東南逐漸變細、磁化率值逐漸變大。 -

The analysis of the large - scale synoptic situation shows that strong precipitation is closely related to the explosion of monsoon and the intensification of cross - equatorial flow which bring a lot of vapor and meet with cold masses at the eastern of northwest district on 8th, june causing extremely heavy rainfall ; that subtropical high - level jet at 200hpa, subtropical high at 500hpa and low - level jet at 850hpa are the weather backgrounds favorable to strong precipitation ; that the pattern of eastern highs and western lows and the establishment of a low - level jet and the coupling between upper - and low - level patterns that determine that the rain occurred in the east of the northwest china ( on average, this is the rainy season for the south of china, but not for the northwest china ) ; that water vapor comes from southerly and easterly flow which converge at the eastern of northwest district with convergence mainly in lower levels and pbl ; that the high value of the whole - level apparent heat source < q1 > is near the area of large rainfall in the direction of northeasterly - southwesterly agreeable to shear line very well and the condensation latent heat releasing is main heat source with vertical advection item playing key role in q1 and q2 ; that there is a vertical secondary circulation crossing low - lever jet whose ascending branch is at the area of large rainfall ; that the construction of convection instability and conditional symmetry instability results that there is not only deep thermal instability, but also moisture influx and triggering mechanism of thermal instability causing strong torrential rain
作為對比，本文還對2002年6月24 - 25日發生在北京地區的強地形雨進行了分析，並討論陜南、北京地區兩地暴雨的異同點以及地形作用的共性和個性，為兩地暴雨預報提供有益的參考，得出了一些很有意義的結果： 1大尺度環流背景分析表明： （ 1 ） 「 02 . 6 」強降水與6月上旬越赤道氣流和季風爆發密切相關，攜帶大量水汽的偏南氣流與冷空氣於6月8日交匯在西北地區東部，導致了這次強降水的發生； （ 2 ） 200hpa的副熱帶西風急流、 500hpa副高以及850hpa的低空急流的配置非常有利於本文分析之陜西強降水的發展與維持。大尺度形勢分析表明，東高西低形勢場、低空急流的建立和高低空形勢的配置決定了這場降雨出現在西北地區東部。與暴雨區相聯系，存在一支橫越低空急流的經向垂直環流，暴雨區處于該垂直環流的上升支； （ 3 ）偏南和偏東氣流水汽通道在西北地區東部交匯，水汽的輻合積聚主要在對流層低層和行星邊界層內完成； （ 4 ）整層的視熱源< q _ 1 >高值區在暴雨區附近呈東北-西南向分佈，與切變線走向非常一致，降水產生的凝結潛熱釋放是強降水區大氣的主要熱源。 -
Seasonal variations of water vapor transport over east asia monsoon region are studied, especially that in summer season. the results indicate that there are four vapor inflow corridors to fetch china : southwest corridor, south china sea corridor, southeast corridor and northwest corridor. it shows impact of south asia monsoon, south china sea monsoon, subtropical monsoon and middle latitude westerly belt on summer rainfall anomaly over china, respectively
分析了東亞季風區水汽輸送的季節變化，並著重研究了夏季東亞季風區的水汽輸送特徵，指出夏季東亞季風區水汽輸送有四條通道到達中國大陸：西南通道、南海通道、東南通道和西北通道，分別體現了南亞季風、南海季風、副熱帶季風和中緯度西風帶對中國夏季降水的影響。 -
( 4 ) in summer, tropic west pacific ssta decadal change infect precipitation decadal change in south and north of changjiang river maybe by : positive ssta in tropic west pacific weaken the summer monsoon circulation, lead more precipitation in south of changjiang river and less precipitation in north of it, vice versa ; middle north pacific ssta decadal change infect precipitation decadal change in mid - down valley of changjiang river maybe by : when ssta is negative in middle north pacific, the height field in tropic rises obviously, the subtropical high strengthens and extends westward, the northern limit retreats southward, leads upper trough retreats northward and move eastward, meiyu front moves northward, then leads more precipitation in mid - down valley of changjiang river, vice versa ; middle northwest pacific - low latitude mid - east pacific infects precipitation in north china possibly by change the activity of northeast china cyclone
（ 4 ）熱帶西太平洋ssta年代際變化影響夏季中國長江南北降水年代際變化的可能機制是熱帶西太平洋海表溫度正（負）異常減弱（加強）東亞夏季風環流，從而使江南降水增加（減少） ，江北降水減少（增加） ；夏季中部北太平洋ssta年代際變化影響中國長江中下游地區夏季降水年代際變化的可能機制是中部北太平洋海表溫度負異常，將導致熱帶地區高度場普遍增高，副高加強西伸，副高北界南退，致使高空槽北縮東移，梅雨鋒西移北進，中國長江游中游、中卜游降水增多，反之亦反；夏季中高緯西北太平洋一低緯中東太平洋反向距平分佈結構影響中國東北降水的可能機制是低緯中東太平洋海表溫為負異常。 -
( d ) in the weak monsoon year, nwc lies in the northwest airflow region, west and south wind, as well as moisture transportation are remarkably reduced. except part of the first field, there is vapour flux divergenceon in nwc ( e ) in the strong monsoon years, the height field is low on the west and high on the east, west and south wind, and it ' s vapor flux transportation, are evidently boosted up. there is vapour flux conflurnce in the he first and sixth region
（ d ）弱夏季風年，西北區高度場西高東低，處于脊前西北氣流的控制之下，西風和南風明顯減小，水汽通量輸送也大大減少，除一區的甘肅河東大部（ 30 35 n ， 101 105 e ）存在水汽通量輻合外，其它地區為水汽通量輻散（弱的輻合） 。 （ e ）強夏季風年，西北區高度場東高西低，西風和南風明顯增強，水汽通量輸送同樣顯著增強，一、三區存在大范圍的水汽通量輻合。 -
The relationship between cef and china summer rainfall and that between cef and tropical cyclone frequence ( tcf ) in the northwest pacific ( nwp ) are investigated. lt is found that the several branches of cross - equatorial flow have different interannual variability. periodicity and interdecadal variability. the five channels in the lower troposphere in the monsoon region of the eastern hemisphere have different relationships with china summer rainfall. the results also show that there are obvious relation between the interannual variatin of cef and tcf from july to october in the northwest pacific
確定了東半球季風區對流層高低層各支越赤道氣流通道的位置，並探討了越赤道氣流與我國夏季降水和西北太平洋上熱帶氣旋發生頻數的年際變化之間的關系。結果表明：季風區夏季的幾支越赤道氣流具有不同的年際變率、周期以及年代際的變化特徵。夏季季風區對流層低層的5支越赤道氣流的強度與我國夏季降水呈不同的相關型。 -
The positive load take absolutely advantage in the first spatial pattern of year and seasons. especially that the precipitation field load of winter is all positive. not in the southwest of china because of southwest monsoon etc. system ; the characteristics of the second spatial pattern are that most of the area is taken up by positive load in year and four seasons, the west of talimu basin is the center of negative load of the year, spring and autumn vector fields ; east of zhungeer basin is the center of positive load of the third spatial pattern of year, spring, summer and winter, the center of negative load is often in east of chaidamu basin, but the distribution center of autumn is in east of zhungeer basin ; the distribution of the fourth spatial pattern is difficult to describe and forms several centers of positive and negative load ; several centers of positive and negative load also appear, the distribution of load fields of the fifth spatial pattern of year, spring and winter represents the situation of " +, -, + " from southeast to northwest ; the complexity of the sixth spatial pattern is more stonger than that of the fourth and the fifth spatial pattern, several centers of load fields of year and each season often appears inverse situation of the positive and the negative load. but the centers are still most in zhungeer basin, chaidamu basin and talimu basin
第一空間型中，年和四季都是正荷載占據絕對優勢，特別是冬季降水場皆為正值，只是西南地區由於受西南季風等系統的影響，表現為與其它地區的不同；第二空間型的特點如下：年和四季分佈皆為正荷載占據大部分區域，負荷載中心年、春季和秋季分佈中都是位於塔里木盆地西部地區；第三空間型正荷載高值中心除秋季外都是處在準格爾盆地以東地區，負荷載中心多在柴達木盆地以東地區，秋季卻處于準格爾盆地以東地區；第四空間型分佈就較復雜無章法可言，形成多處正負荷載中心；第五空間型特徵是這樣的，同樣是多個荷載中心出現，年、春季和冬季中的荷載場分佈從東南到西北大體呈現「 + 、 - 、 + 」的特點；第六空間型分佈的復雜程度較之第四、第五空間型更大，年和各季分佈比較中多個荷載中心常出現正負相反的情況，但中心仍以柴達木盆地、準格爾盆地和塔里木盆地為主。 -
