| 4. | This scheme was finally tested by a typical meso - scale severe rainstorm process which happened on the middle - lower parts of the yangtze river in china during the period of july 4th - 5th , 2003
并以2003年7月4日? 5日发生在江淮流域的特大暴雨过程为例，对该方案进行了验证。 |
| 5. | Analyzing the physics structure of vorticity , divergence , vertical velocity , frontogenesis " function , apparent heat source and apparent moist sink etc . indicated the physics fields are favorable for the occurance of the heavy rain over changjiang - huaihe river basin where the physics values are well according to the heavy rainstorm positions ; the low level jet is closely subject to the moisture and the coupled system of the low and the upper level jetstreams induced the strongly " ascending motion ; the intensity of the frontogenesis varies with the development of the rainfall system and reacts the rainfall intensity
主要分析了这次过程中的多种物理量，包括涡度、散度、垂直速度、锋生函数、视热源、视水汽汇等，对这一暴雨过程有了比较系统的认识。结果表明：在江淮流域存在着有利于发生暴雨的物理量场配置，涡度、散度、垂直速度等物理量，与暴雨的落区都很吻合的；低空急流的产生不仅有利于水汽的输送，而且高低空急流的耦合造成了有利于强上升运动的配置；锋生强度随着降水系统的发展变化，并影响降水强度。 |
| 6. | ( 4 ) the correlations are significant between the sth position index and the general circulation . in the westerly ( easterly ) year , equatorial westerly is weaker ( stronger ) , cross - equatorial flow is weaker ( stronger ) , south china sea summer monsoon is weaker ( stronger ) , the yangtze river valley westerly is stronger ( weaker ) , which has the positive ( negative ) effect on the maintenance of rain band over the yangtze river valley , so the rainfall is more ( less ) in this area and it is hit by floods ( droughts ) , vice versa
( 4 )本文运用定义的副高指数研究了六月份副高偏东偏西年份的大型环流特征及其对我国东部天气的影响，风矢量场和相关场分析结果表明：副高偏西(东)年，赤道西风减弱(增强) ，越赤道气流偏弱(增强) ，南海夏季风偏弱(强) ，而长江流域西风增强(减弱) ，有(不)利于雨带在江淮流域维持，该地区降水偏多(少)易涝(旱) 。 |
| 7. | Both composite and correlation analyses show that the 150hpa asia - australia cef ( aacef ) in boreal spring has important influences on easm . when aacef is weaker , the summer wpsh tends to be stronger with a southwestward extension , and the south asia high ( sah ) will be stronger too . this circulation pattern will lead to more rainfall in the yangtze and huaihe river valley and less rainfall outside of this region
相关分析和合成分析的结果还显示，春季150hpa亚澳越赤道气流对东亚夏季风有重要影响：当春季该气流偏弱时，北半球夏季西太平洋副高强度偏强，位置偏南偏西，南亚高压强度也偏强，这样的环流背景使江淮流域6 ? 7月降水偏多，华南华北降水偏少；反之，当春季该气流偏强时，夏季西太副高强度偏弱，位置偏北偏东，南亚高压强度也偏弱，江淮流域夏季降水偏少，华南华北降水偏多。 |
| 8. | During the lasting course of type e , 850hpa , 500hpa and 200hpa wind field is obviously different from that during the lasting course of type c . the same is true of the precipitation deviation distribution of china , and during type e course the monthly precipitation deviation is positive over the yangtse river and huaihe river basin and negative over north china . the situation of type c is opposite . the result is mainly to reflect the situation in june
E 、 c型持续过程期间， 850hpa 、 500hpa 、 200hpa风场存在明显差异。我国降水量距平分布也有明显差异， e型过程江淮流域月降水量为正距平，华北为负距平， c型则相反，而这个结果主要是反映了6月份的情况。 |
| 9. | The key area of the first eigenvector of eof for summer precipitation decadal change in china allots in south and north of changjiang river which vary contrary ; the second one ' s allots in middle valley of changjiang river and jianghuai valley ; the third one ' s allots almost in total china . ( 3 ) tropic and north pacific summer ssta ' s decadal change has good correlation with china summer precipitation ' s decadal change
中国年平均与汛期平均降水eof分析的前三个特征向量基本一致，第一特征向量表现为长江南北反向的形态，第二特征向量表现为中部为正，其余为负的分布形态，第三特征向量表现为长江中游、江淮流域为正，其南北两侧为负的分布形态。 |
| 10. | There are certain relations between circulation pattern index ' s decadal variance characteristic and decadal variation tendency of the precipitation of china : in the 1960s and the 1970s , in which the negative index are relatively more , the precipitation are abundant , and in 1980s in which positive index dominant the precipitation over north china are obvious deficient ; the situation of the yangtse river and huaihe river basin is opposite
流型指数的年代际变化特征与我国降水的年代际变化趋势有一定的关系，负指数偏多的60 、 70年代华北降水偏多，而正指数占优势的80年代华北降水则明显偏少；江淮流域的情况则相反。 |
