As 22 january 1999 was a fine day , the signal returns captured by the terminal doppler weather radar tdwr were too weak and the westerlies were too shallow for any windshear event to be detected using tdwr data . a windshear alert had been issued following receipt of aircraft report 由于一九九九年一月二十二日天气晴朗，机场多普勒天气雷达( tdwr )收集到的回波讯号相当微弱，而且西风也太浅薄，以致未能根据tdwr数据探测到风切变现象。
Diagnostic results show that the westerly wind stress anomaly and convergent meridional wind stress anomaly over the tropical pacific correspond to the every el nino , and the easterly anomaly and divergent meridional wind stress anomaly correspond to the vanishing of el nino 通过研究表明，每次elnino事件在热带太平洋都伴随着西风应力异常以及向赤道辐合的经向风应力异常，东风应力异常及向两极辐散的经向风应力异常与elnino消亡对应。

Results show that subtropical high in june 1998 is more intensive and westerly and than normal , leading to the floods in yangtze river valley . vertical diabatic heating has stronger impacts on the variation of intensity and location of western pacific subtropical high 结果表明： 1998年6 - 7月西太平洋副高较常年同期偏强偏西，从而导致了我国长江流域持续暴雨洪涝天气的发生；副热带地区的非绝热加热对副高的强度和位置的变化有极其重要影响。
During the el nino ( la nina ) events , the negative ( positive ) sst anomaly occurs and the corresponding the olr mjo intensity weakens ( enhances ) in the tropical western pacific ; at the same time , the positive ( negative ) surface westerly anomaly leads to positive ( negative ) mld anomaly , and the corresponding sst mjo intensity weakens ( enhances ) in the equatorial eastern pacific , 4 ) the interdecadal variation of the atmospheric mjo intensity took place distinctly in 1970s in the tropical western , northwest and eastern pacific , with the stronger intensity in the former than the back stage , and the interdacadal variation of sst is its cause Elnino ( lanina )事件中热带两太平洋sst出现负(正)异常， olr季内振荡强度出现减弱(增强)的变化。 elnino ( lanina )事件中，赤道太平洋出现地面信风西风分量正(负)异常，并引起热带东太平洋mld出现正(负)异常，造成热带东太平洋sst季内振荡强度出现减弱(增强)的变化。 4 )热带印度洋、热带西太平洋和热带东太平洋季内振荡强度在上世纪70年代发生了明显的年代际变化，均为前弱、后强， sst本身的年代际变化是其原因。
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。
