| 1. | East asia north wind indexes in drought years are larger than in flood years on each levels
各层少雨年东亚北风指数都大于多雨年东亚北风指数。 |
| 2. | ( 2 ) tpnes precipitation anomalies is the highest in northwest china , and the dry years are more than the wet years , whereas no the lasting dry years
( 2 )青藏高原东北侧区是西北地区降水异常最为敏感的区域，其少雨年的概率大于多雨年，但不存在持续少雨年。 |
| 3. | The southern asia high and the subtropical high of the more precipitation years and colder years are both more weak ; the southern asia high and the subtropical high of the more precipitation years and colder years are both more strong
多雨年和凉年的南亚高压和副高都较常年偏弱、少雨年和热年的南亚高压和副高都较常年偏强。 |
| 4. | ( 3 ) the polar eddy , the west circumfluence on 500hpa medium latitudinal region ands subtropic circumfluence are the key systems of tpnes floods precipitation and , the wet years have abundant vapor , moreover , the omga is positive in all atmosphere
( 3 )极涡、中高纬西风环流系统和副热带系统是影响青藏高原东北侧区汛期降水的大尺度环流背景关键系统。同时，多雨年的主要流场特点是有利于水汽输送，且整层大气始终表现为上升运动。 |
| 5. | The atmospheric circulation of the wet year deviate from enso year to no - enso year . in enso year , the subtropical high is strong with the deepening of trough over south of baikal lake while in no - enso year , the subtropical high is weak with the high incidence of typhoons over northwest of pacific and south china sea
多雨年发生在enso年和no - enso年大气环流形式的不同主要表现在： enso年副热带高压较强，贝加尔湖地区南部低压槽容易加深；在no - enso年副热带高压强度减弱，在西北太平洋和南海地区多热带系统活动。 |
| 6. | Longitude circulations exist in the soohpa height fields in wet . springs and latitude circulations exist in dry springs . the composite : differences of the atmospheric circulation exist in wet springs and dry springs , which appears to be the eu teleconnection pattern of the general circulation
结果表明，山东省春季涝年与旱年的环流形势存在明显的差异：异常多雨年，贝加尔湖以西的广大中高纬地区高度场降低，我国东部到日本的高度场明显升高，亚洲中高纬地区呈现纬向环流。 |
| 7. | The precipitation character of the middle part of viet nam and its relation to the atmospheric circle . the autumn precipitation of the middle part of viet nam has obvious variations in inter - annual and inter - decade scale with clearly quasi 6a , 10a , 15a period ; in heavy rainfall years , there are a positive anomaly over the north - west pacific and a negative anomaly over japan ; while in deficient rainfall years , the anomaly distribution is on the contrary ; 4 . the precipitation character of the south part of viet nam and its relation to the atmospheric circle . the research finds that the rainfall of the south part of vietnam usually concentrates in the autumn every year and a clear difference of atmosphere condition exists between that of flood and drought years
越南中部降水变化特征及其与大气环流和海温的关系越南中部秋季降水具有明显的年际、年代际变化特征，具有明显的准6a 、 10a 、 15a左右的周期；越南中部多雨年， 500hpa高度距平场在热带西北太平洋为正距平，日本附近上空为负距平；而少雨年则相反；越南中部多雨年，热带中东太平洋海温异常偏高，西太平洋海温异常偏低；少雨年则相反；越南中部多雨年，登陆越南的台风频数偏多；而少雨年则相反。 |
| 8. | 4 , the summer rainfall anomaly in northeast china bears close correlation with the atmospheric circulation backgroud . while cold air in middle and high levels of troposphere is active in wet year with the positive anomalies over high - latitude and polar area , the active longwave ridge , the anomalous long - wave ridge in northeast china and inner - mogolia as well as the northward and eastward of the polar vortex , the contrary is in the dry year in northeast china
4东北地区夏季降水异常与大气环流背景有密切的关系，东北地区夏季多雨年在对流层中、高层冷空气比较活跃，高纬和极区主要由位势高度的正距平所控制，贝加尔湖以北的地区长波脊较为活跃，在东北地区和蒙古地区有异常的长波槽发展，极涡位置偏北、偏东；而在东北地区夏季少雨年则容易出现与上述相反的异常环流形式。 |
| 9. | The vertical velocity in low troposphere is larger than high troposphere , and vertical velocity in flood year is also larger than that in drought year . the vertical velocity on different levels show that there exists distinct sinking motion from midlevel to uplevel of troposphere in drought years and updraft in whole atmosphere in flood years
垂直分布曲线均呈s形，垂直上升速度在对流层低层大于对流层上层，多雨年大于干旱年;不同层次上垂直速度分布图表明，旱年对流层中上层盛行下沉气流，而涝年整层大气始终表现为上升运动。 |
