The low-level wind field displayed cyclonic character on the north part of the squall line, whereas on its south part the wind field pattern was anticyclonic, with clear convergence of westerly and southeast inflows in between.

飑线不同位置的水平风场结构有很大不同，在飑线北端，低层是气旋性辐合风场，飑线南端是反气旋性辐合风场，而中部沿强对流窄带的前部是偏西和东南风的风场辐合。

Numerical results show that the major change is the environmental circulation of tropical cyclone when the surges immerge into the outmost of the tropical cyclone.

通过研究冷暖空气对热带气旋发展影响的试验发现，冷暖空气在入侵热带气旋外围时，最主要改变的是外围的环流场。

Before the occurrence of ENSO, due to the anticyclonic anomaly in midlatitude of the South Indian Ocean, the anticyclonic anomaly over Australia tends to be enhanced through the dispersion of Rossby wave; In the meantime, the equatorial convergence of the southerly anomaly off the east of Australia and the northerly anomaly in the Philippine excite the onsets of the westerly anomaly in the equatorial western Pacific and the occurrence of ENSO.

在ENSO发生前，南印度洋中纬度为反气旋异常，并通过Rossby波的频散作用加强了澳大利亚附近的反气旋异常；同时，澳大利亚东部沿海的南风异常与菲律宾附近的北风异常在赤道辐合，促进了赤道西太平洋西风异常的爆发和其后ENSO的发生。

Initially, if the thermal wind vorticity of wind field is larger than that of the temperature field, and the horizontal scale of the disturba...

这种不稳定的作用，可在较短的时间内(约24小时)造成上层是反气旋、下层是气旋和中心为暖中心的猛烈的涡旋形成。

The eddy flow around waterspout of a tub and the cyclone in the bottom of a typhoon are convergent flow-in rotational flow .

水槽排水孔形成的旋涡和台风底层的气旋都是Coriolis力作用下的辐合流入层旋流，台风顶部是辐散流出层气旋。

On the basis of this, the role of condensational latent heat release is studied emphatically and a conceptual model of mutual positive feedback mechanism between the growing of meso-α-scale cyclone on MeiYu front and its accompanying intensifying precipitation due to stable condensational heating is posed, i. e. condensational heating generates negative allobar, divergent wind kinetic energy promotes meso-α-scale cyclone growing, and simultaneously, updraft motion is also reinforced, precipitation continues intensifying.

并在此基础上着重对凝结潜热释放的作用进行了研究，提出了一种由稳定性凝结加热作用而导致的梅雨锋上α中尺度气旋发展与降水增强之间相互正反馈机制的概念模型即凝结加热可以产生负变压，变压风动能通过转变为旋转风动能促进中气旋发展，同时上升运动得到增强，降水增幅。

The time of peak value of low frequency u wind isprior to the peak of rainfall in flood years;(3) There are low frequency OLRmoves northward at low-latitude and southward at mid-latitude at the same time inflood years , the join point is between 20-30 N.

3涝年低频OLR在经向上同时存在由低纬度向北和由中高纬向南的传播，二者交汇在20～30°N之间。旱年则没有显著的汇合区。(4)影响我国东部的低频气旋和反气旋源地在北半球中纬度太平洋和低纬的菲律宾附近。

When a tropical cyclone near the center of the largest wind power is less than 8 hours as the tropical low pressure, 8 and 9 as the tropical storm's winds, 10 and 11 the wind was stronger tropical storm, the only center in the vicinity of the largest wind power reached 12 tropical cyclones It is called a typhoon.

当热带气旋中心附近最大风力小于8级时称为热带低压，8和9级风力的称为热带风暴，10和11级风力的为强热带风暴，只有中心附近最大风力达到12级的热带气旋才称为台风。

Taking advantage of potential vorticity thinking and vortex Rossby wave theory, we verify the existence of waves like VRW that is dynamical mechanism for intensity change.

利用位涡表征的螺旋雨带以及涡旋—Rossby波理论，探讨气旋加强与减弱的成因机理，证实了气旋环流中确实存在有涡旋—Rossby波性质的波动。

This paper is a part of the "Studies on characteristics of acidrain subsidence and its prevention,"adout the weather feature in Qingdao area. It lays emphasis on both boundary layer pollution meteorological characters and acid causing substance sources.It points out that boundary layer has special nature in Qingdao.

青岛地区酸雨成因研究表明，青岛市近代工业发展排放大量致酸物质、海洋上天然排放的二甲基硫是重要的原因；青岛地区边界层风场和温度场的特殊规律是形成酸雨的另一个重要原因；江淮气旋和黄淮气旋大型天气形势起了辅助作用。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
