quasi-biennial oscillation meaning in English
准两年振荡
Examples
- Tthe quasi - biennial oscillation , an oscillating phenomenon in which the wind in the upper atmosphere over the tropics changes its direction from east to west and then back to east about every two years
准两年振荡发生在赤道附近的高空，分为西风异常和东风异常两个交替出现的位相，周期约为两年。 - ( 2 ) in the condition of quasi - quadrennial or quasi - biennial oscillation , monthly mean anomaly fields of slp , ssta , x and f have the most important effect on the linear response of nino3 . 4 , and there exists obvious spatial symmetry among cold and warm events of enso oscillation
( 2 )在准4a或准2a振荡下， slp 、 ssta 、 _ x 、和_ y的月平均距平场对于nino3 . 4指数的线性响应占主导地位， enso振荡的冷暖事件间具有明显的空间的对称性。 - ( 4 ) latitude and meridional wind stress fields both have the character of quasi - quadrennial and quasi - biennial oscillation , but their phases are different . so their conjunct effect makes enso oscillation have both quasi - quadrennial and quasi - biennial periodicity and erratic , which causes the forecast of enso events uncertainty
( 4 )纬向和经向风应力距平场具有准4a和准2a的振荡性质，但是位相存在差异，因此共同作用下造成enso振荡既有准4a和准2a的周期性，又有不规则性，对于enso事件的预报带来不确定性。 - The probability distributions of climatic elements are discussed . based on the characters of them , a multimode model is introduced and verified through the nonlinear fitting . the climate features of quasi - biennial oscillation of the stratospheric zonal wind over equator , the enso index , the surface pressure at reykjavik 21 90w 64 13n and swedish temperature , and the northern hemisphere tree ring all show that the multimode are universal in the climatic system
对气候要素的概率分布进行了讨论，根据这些概率分布的特点提出了多模态模型，并用非线性拟合的方法进行了验证。对赤道平流层纬向风enso指数esi序列冰岛reykjavik 21 . 90w , 64 . 13n气压和瑞典温度北半球树木年轮等数据的分析表明：气候系统中多模态现象具有普遍性。
