亚澳季风区内水汽汇的准两年振荡及其与大气环流的关系 |
| 3. | In the eastern monsoon region , transition of summer rainfall from below normal to above normal in the lower yangtze river in 1979 was accompanied with dry trends in north china and south china
与全球增暖相联系的是：我国微量降水在空间上表现为一致的减少趋势，我国北方寒潮事件显著减少，冷夜和冷日的减少与暖夜和暖日的增多并存，以及极端强降水有增多的趋势。 |
| 4. | The 1st time coefficient shows the staged feature of the progression of the moisture transport over asian - australian monsoon region , which relates with the large - scale important weather incidents in asian - australian monsoon region . iv
第一特征向量对应的时间系数图表现了亚澳季风区4 - 9月份的水汽输送阶段性的时间演变特征，可反映夏季亚澳季风区的大型天气事件的发生变化过程。 |
| 5. | In this study , we have analyzed the time - space variation characteristics of global cross - equatorial flow ( cef ) at the lower and upper rroposphere . especially for the monsoon region of the eastern hemisphere . the ncep / ncar reanalysis dataset used in this study are from 1958 to 1997
本文利用1958 1997年ncep / ncar逐月再分析资料，分析了全球各经度不同层次上越赤道气流( cef )的时空分布特征，尤其是东半球季风区夏季的越赤道气流。 |
| 6. | Climatological characteristics , which can provide some drought or flood years with large - scale background , are investigated for large - scale water vapor transport over asian - australian monsoon region based on vertically integrated water vapor flux by pentad from 1980 to 1997 . at the same time , the differences of moisture transport over the yangtze river basin between drought and flood and the moisture budgets over eastern china from april to september are examined . major results are as follows : i
使用1980 ? 1997年垂直积分的整层水汽输送通量资料，从气候平均的角度分析了亚澳季风区大尺度水汽输送演变和偏南风水汽输送在东亚地区推进的气候特征，为研究异常年份旱涝事件的产生提供了相应的大尺度背景；同时还讨论了长江流域旱涝年水汽输送的差异以及4 - 9月我国东部各区域的水分收支情况。 |
| 7. | 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
分析了东亚季风区水汽输送的季节变化，并着重研究了夏季东亚季风区的水汽输送特征，指出夏季东亚季风区水汽输送有四条通道到达中国大陆：西南通道、南海通道、东南通道和西北通道，分别体现了南亚季风、南海季风、副热带季风和中纬度西风带对中国夏季降水的影响。 |
| 8. | The most obvious feature of the first leading term of eof applied to the climatic vertically integrated water vapor flux over asian - australian monsoon region shows a planetary - scale southwesterly moisture transport , starting from south hemisphere , passing over asian monsoon region and flowing into north pacific , which indicates the interaction between the northern and southern hemisphere as well as between mid and low latitudes in the northern hemisphere
( 3 )亚澳季风区气候平均状态下4 - 9月份的水汽通量的eof矢量展开的第一特征向量最显著的特征是存在一条行星尺度的强西南风水汽输送带，它源于南半球低纬地区，经过亚洲季风区，进入北太平洋地区，集中反映了南北半球和中低纬各支水汽输送气流的相互作用。 |
| 9. | In winter ( january ) , there are four nearly latitudinal moisture transport belts ( channel ) over asian - australian monsoon region . they are closely related with the easterlies and westerlies over southern hemisphere and northern hemisphere . in boreal winter , asian monsoon region is moisture source ; the cross equatorial moisture transport channels transport the moisture to australian monsoon and south indian ocean from asian monsoon region
主要结论如下： ( 1 )冬季( 1月)的水汽输送形势与南北半球东、西风带紧密联系，主要有四条近似纬向分布的垂直积分的强水汽输送带，越赤道输送将水汽从亚洲季风区输送到南半球澳大利亚季风区和南印度洋季风区，亚洲季风区为水汽源区。 |
| 10. | 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
确定了东半球季风区对流层高低层各支越赤道气流通道的位置，并探讨了越赤道气流与我国夏季降水和西北太平洋上热带气旋发生频数的年际变化之间的关系。结果表明：季风区夏季的几支越赤道气流具有不同的年际变率、周期以及年代际的变化特征。夏季季风区对流层低层的5支越赤道气流的强度与我国夏季降水呈不同的相关型。 |
