低压中心

在东风气流中，低压中心位于15～20°N之间，低压中心位置跟实际热带东风气流中低压形成位置比较一致

In the easterly flow , the center position of depression appears between 15 ° N to 20 ° N. The center position of depression is relatively consistent with the position of depression formation in the observational tropical easterly flow . COMPARE

文中还揭示：臭氧总含量的低值和高值区通常分别与500hPa高度场的高压中心和低压中心相对应。

Also , this paper reveals that high ( or low ) values of total ozone amount usually correspond to the low ( or high ) at 500 hPa height field .

高低压中心、槽线识别的初步试验

A Test of Recognition of Centres of High and Low Pressure and Trough-Line

低压中心高度值的频数分布是双峰型。

The frequency distribution of cyclone center heights appears in a two peak type .

一种是气旋，在低压中心的四周形成旋转的螺旋气流时就出现了气旋。

One is the cyclone this happens when the windsform a circulating spiral around the low .

所分析的地面低压中心位于中（尺度）气旋之东约8公里处。

The analyzed low-pressure center at the surface was located ~ 8 km east of the mesocyclone .

地面中尺度低压中心和与之配置的切变线北侧对特大暴雨落区有较好的指示。

The center of the surface mesoscale depression and the north of the shear line are indicative to the rainfall area .

地面气压场上，低压中心位于日本海，冷锋已经越过山东半岛，渤海和山东半岛处在庞大的冷高压控制之下。

In surface pressure field , huge cold high pressure controls Bohai sea and Shandong peninsula , and low pressure lies in Japan sea .

当热带东风气流减弱时，低压中心位置偏北，低压强度增强，低压纬向宽度变大；

When the tropical easterly flow decreases , the center position of depression moves northward , the strength of depression increases and the zonal width of depression widens .

与此对应，中央北极区及气候冰岛低压中心海平面气压在降低，而再往南区域海平面气压在升高。

Meanwhile , the sea level pressure in the center part of the northern polar region and the region where the climatic Icelandic low exist decreases , but in places farther southward it increases .

而且，季风槽向南移动轴的今天经过比卡内尔，迪萨，贾巴尔普尔，赖布尔，低压区中心。

And , the southward moved axis of monsoon trough today passes through Bikaner , Deesa , Jabalpur , Raipur , Center of low pressure area .

通过对试验数据的分析，判断出低压转子中心孔的堵头落入联轴器内孔，据此进行了针对性的检查，证实了这种判断的正确性。

Through the analysis of testing data , it was thought that the loose caulking block of center bore of low pressure rotor fell into the internal opening of coupling , and the following inspection proved the correctness of judgement .

如果大片地域产生气压差，风开始以巨大的圆形路线行进。高压的空气被牵引到低压区的中心。

If the pressure changes over a large area , winds start to blow in a huge circle . High-pressure air ( area ) is pulled into a low-pressure center .

将电压从中压变至低压的电厂负荷中心单元变电站，也从厂用母线获得电源。

Load-center unit substations , where the power is transformed from the medium voltage level to the low voltage level , are also powered from the auxiliary buses .

在安装中，对制造厂家有关低压转子联轴器找中心的设计值提出了修正意见，最终保证了在额定工作氢压状态下整个轴系的安装达到要求。

During the installation , amendments were made to the manufacturer 's design values on the alignment of LP rotor by coupling , thus ensuring the final success of shafting installation at rated working hydrogen pressure .
