moisture flux meaning in English
水汽通量
Examples
- The elements of vorticity , divergence , specific humidity , moisture flux divergence and k index etc . were benefited to the form and development of storm rainfall over the rainfall region
降水区上空的涡度、散度、比湿、水汽通量散度、 k指数等要素有利于暴雨的形成和发展。 - We also analyzed the elements of vorticity , divergence , specific humidity , moisture flux divergence , wind - field , wind shear , maximum lifting speed and so on in the snow - storm of north - east china , found that they are favorable for and benefited to the formation and development of snow - storm
对2000年1月同一天不同时刻发生在西北和东北的一场暴雪过程进行了对比分析，发现两地暴雪虽发生在同样的大尺度环流背景下，但却在很多方面有不同之处。 - The result indicates that , in the course of the rainstorm in huoshan , there are obvious low - level jet of great intensity , infection of mesoscale shear line , enhancement of plus vorticity which increases intensity of convergence , improves ascending velocity and brings on precipitation , and quick enhancement of helicity which provides the basis to forecast , in addition , convergence of moisture flux and analyzed potential vorticity which reflects baroclinic convective instability sufficiently indicate the characteristics of the rainstorm
结果表明：此次霍山暴雨发生前后，存在明显的大强度低空急流，并受到中尺度切变线的影响，而且正涡度的加强引起了辐合加剧，提高了上升速度从而引起降水，同时暴雨发生前螺旋度的迅速增强，也为预报提供了根据，另外水汽通量的辐合以及分析位涡反映出的斜压对流不稳定都充分体现了这次降水的特点。 - When the southwesterly ( northeasterly ) moisture flux over southern china and its vicinity increased , then more ( less ) water vapor was transported from the low latitudes to the atmosphere over southern china , which resulted in strong ( weak ) atmospheric moisture sinks over the above - regions in southern china
华南中东部以及广西北音队湖南西部贵州东部地区水汽汇的强度异常与东亚上空水汽输送异常导致上述地区垂直积分的水汽通量辐合的异常密切相关，当中国南方上空有西南（东北）风水汽通量距平，即西南风水汽输送增强（减弱）时，则上述地区上空的水汽汇偏强（偏弱） 。 - In the first part of paper , we introduce the appliance of doppler weather radar in meteorological work in the near future , and simply enumerate all kinds of adjoint methods to retrieve data of radar . in the second part of paper , we choice some methods that are usually used domestically and overseas , compare excellence and flaw of the methods by using data of simulate wind field , analyze synthetically the precision of simulate result , the length of retrieval time and the structure of data distributing , lastly decide to regard ameliorated quasi - 4d adjoint method as retrieval technology in the paper . in the third part of paper , we retrieve the data of single doppler weather radar in hefei , anhui province , then calculate 3d wind field , streamline field , divergence , vorticity , helicity , moisture flux , divergence of moisture flux and potential vorticity from the result of retrieval
文中第一部分对近年来多普勒天气雷达在气象工作中的应用作了介绍，同时简单的罗列了反演雷达资料的各种变分方法；接下来在第二部分选取了几种国内外常用的反演方法，利用模拟的风场资料比较各种方法的优缺点，从模拟结果的精度、反演时间的长短、资料的分布结构上综合分析，最后决定将已做改进的准四维变分分析方法作为本文的反演工具；第三部分就是反演安徽合肥多普勒天气雷达资料，然后由反演得出的风场计算了各个时间各个层次的三维风速、流场、散度、涡度、螺旋度、水汽通量、水汽通量散度和位涡。
