    在欧亚冬季积雪异常偏重的年份,大气环流出现显著异常: 500hpa位势高度场上径向气流占优势,东亚大槽偏强,高度场槽后西北气流偏强,造成影响我国东部地区的冷空气偏强,出现“冷冬天气” 。我国春季降水对欧亚冬季积雪异常的响应最为显著,重雪年春季我国长江流域以南大部地区出现明显的降水负异常
  • There is a north - north - east negative anomaly belt of aerial magnetism in the middle - east part of the basin , which could be displayed by the aerial magnetism of commutative field , upwardly continuation , lvt in earthquakes , the experimentation of granite liquation ( demagnetization ) , the distribution of neozoic era volcanic rock , earthquake , hot spring and ground feature . the anomaly shows the blocking in east - west direction , and it is also associated with intense activity of deep heat interaction and the development of the crust - mantle mixed layer in the north qiangtang
    从区域航磁、向上延拓、地震低速层、花岗岩熔融(退磁)实验、新生代火山岩的分布、地震、温泉、地貌等发现,盆地中东部存在一北北东向航磁负异常带,既显示出东西分块,也与北羌塘深部热力作用强烈活动、发育“壳幔混合层”有联系。
  • The research showed that : from january to march , the acreage average ozone gross gathered , which was synchronized with the increase of the frequency of strong ssw event . furthermore , the change tendency of ozone gross in the atmosphere break forward and backward 1990 . after the1990s , ozone gross in the atmosphere appeared negative anomaly in the mid and high latitude of north hemisphere from january to march , which was consistent with the obvious descent of appearance frequency of strong ssw event after the 1990s
    分析表明: 1至3月,臭氧总量的面积平均逐渐增高,这与强ssw事件频数1至3月增高同步;此外,大气臭氧总量趋势变化以1990年前后存在明显的突变, 90年代以后,北半球中高纬1 ? 3月间大气臭氧总量处于负异常阶段,这和90年代以来强ssw事件发生频数明显下降相吻合。
  • On the paas - normalized plots , the parent granite and the granite weathering crust are enriched in lree without ce anomaly . while the groundwaters are also enriched in lree , they display significant negative ce anomaly , indicating the fractionation of ce during water - rock interaction . based on the study of two profiles of granitoid weathering crust , we concluded that ree concentrations in the groundwaters from the granitoid weathering crust are likely related to the continued chemical weathering , as well as the ree concentrations in the crust near the water table , clay concentration and the wate r ph values
    地下水与母岩、风化壳稀土的paas标准化分布模式基本相似,呈lree富集型,母岩中无ce异常,而水样中有ce负异常,表明ce在水岩作用过程中发生明显的分异;通过研究两个典型花岗岩风化壳剖面发现,地下水的稀土含量与连续的化学风化,以及水位附近剖面上的稀土含量、粘土矿物含量以及水的ph值等有关。
  • ( 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
