  circulation
In a discharge passage with a guide blade discharge circulation and secondary flow because of bend pipe, the flow in a 1-channel discharge passage of an axial flow pump is a complicated spiral flow.
      
As for the 1-channel passage, the axial-flow pump outlet circulation is usually too big; the passage hydraulic losses are also big, but a small circulation can slightly reduce hydraulic losses.
      
The outlet guide blade with a small discharge circulation or without circulation could reduce discharge passage hydraulic losses and increase pump assembly efficiency by 6%-11%.

In the summer half year,the average intensity of the Pacific high pressurechanges more or less abruptly.It strongly increaseses from June to July and de-creases gradually from April to June.In middle September it decreasees suddenly. In.the summer season(from June to August),tha advance and retreat of theWestern Pacific pressure ridge(moving from east to west or reversed)is intimatelycorrelated with teh upper westerlies.At the same time,the Pacific High itselfis an important factor of the atmospheric circulation.When the zonal circulationis strong,the intensity of the Pacific High is also relatively strong and the posi-tion of the western Pacific pressure ridge changes little.When the small wavesin the westerlies move out from Asia into the Pacific Ocean,the position ofthe western Pacific pressure ridge only vibrates slightly.But,when the waves in thewesternlies are strong,the western Pacific pressure ridge advances westward andthen retreats eastward apparently.The period advance and retreat of the ridgeis about five or six days During the period of fow zonal circulation index, thewestern Pacific pressure ridge moves eastward.when the circulation index growsfrom low to high,the ridge advances westward.The range of longitudes ofoscillation of the ridge in this type is largest,about 30-40 degrees,and the periodof oscillation is longest,about half month in general.The longest period reachesone month. Besides,the movement of the Pacific High ridge is also studied in relationto he tropical systems,such as typhoons.

夏半年太平洋高压的平均变化,带著突变性质的增强和减弱,突然的增强发生6月到7月,而4月至6月更有逐渐减弱的趋向,到9月中旬以後则突然的减退。 夏季西太平洋高压脊的东西进退和整个西风环流变化及西风环流的情况密切关连,同时太平洋高压本身也是西风环流及其变化的重要因素之一。当西风环流强时,太平洋高压比较强大,这时太平洋高压脊的变化很少,在西风环流小波动东移的过程中,太平洋高压脊只有微小的摆动。但西风带波动较大时,随着西风槽和高压脊的东移,太平洋高压脊便有了比较长时期的和明显的东退和西伸,它的周期一般都在5、6天左右。如果西风环流起了大型的变化,即西风环流由强转弱,再由弱转强,太平洋高压脊随之不断的东退和西伸,进退的范围可达30-40经距。它的周期较长,一般都在半个月的光景,最长的可达一个月,10天以内的很少。 太平洋高压脊除了和西风带的环流,极地高压和低压槽有关外,也和它南边的气压系统,如台风和热带风暴有关。

Integrating with respect to time the equation for the balance of angular momentum of the atmosphere north of certain latitude (30°N say)we obtainIn the above equation ρ is thedensity; (?), the zonal wind; v, the meridional wind; R, the earth's radius; Ω, the angular speed-of the earth's rotation; dm, the mass element of the atmosphere; dτ, the volume element; ds, the area element on the earth's surface, and dσ, the urea element on the vertical surface over the latitudial circle of 30°N. The first two terms (in the parenthesis) On the left side of (2) are evaluated from the mean westerlies in summer and winter given by Mintz. The last two terms on the left and the first two terms on the right side of (2) are evaluated from the mean surface pressure charts of July and January. The transfer of angular momentum across latitude 30°N given by Starr and White is used to evaluate the 3rd. term on the right. Then the value of the last two terms in the parenthesis on the right of (2) is calculated. The result agrees very well with that obtained by other authers.It is further found that: 1. From summer to winter the transfer of angular momentum from low to high latitudes by gross weather systems overcompensates the destruction by the earth's surface. The small residue of these two factors acounts for the main part (about85%)of increase of westerly circulation from summer to winter. The remaining small part of the increase of the westerly circulation may be acounted for by the advection of mass of the atmosphere, which carries the angular momentum due to earth's rotation (difference between the first two terms on the right and the last two terms on the left side of (2)).2. The transfer of angular momentum or the destruction of angular momentum, as well as the intensity of the westerly circulation has annual variation. However this annual variation is not of sine or cosine type, i,θ, the variation from summer to winter is not the opposite of that from winter to. summer. The property of this asymmetry is explained by the irreversible heat addition and subtraction. From winter, to summer heat is added to, and summer to winter heat is subtracted from the atmosphere (N.H.). Since the process of adding and subtracting heat is irreversible, the variation from summer to winter can not be symmetric to that from winter to summer.3. Transfer of angular momentum from easterlies to westerlies occurs mainly in the period of breakdown of zonal circulation (low index), mainly in the belt of longitudes of"extended troughs" (troughs extending from high to low latitudes) and "extended ridges" (ridges extending from low to highlatitudes), and mainly in the high levels of the atmosphere.

把30°N以北大气角動量平衡方程由七月積分到一月,則其中各項都可計算:此緯度以北大气相对西風角動量的改变可用Mintz平均西風冬夏分佈圖算出;地轉角動量的改变可用冬夏地面平均气压圖算出;通过30°N緯度的角動量的渦動輸送已为Starr和White算出,因此利用積分結果可求得30°N以北地面应力和山脈东西兩側气压差所引起的角動量消耗,結果与别的作者用别的方法所得數值極为符合。 作者更指出: 1.从夏到冬大型天气系統的角动量輸送勝过地面摩擦的消耗,从夏到冬西風环流增强的主要部分(約85%)即由於二者之差,西風环流增强的其餘一小部分則由於大气的質量平流,而引起地轉角動量的傳送。 2.角動量的输送,角動量的消耗以及西風环流强度都有年变化。但这种年变化並非正餘弦型,即从夏到冬的变化並不正是从冬到夏变化的反面,此种非对称性可由加熱过程和减熱过程的不可逆性解釋。在北半球从冬到夏对大气來说是加熱的,而从夏到冬大气失去熱量,因为加熟过程和減熱过程都不是可逆的,故从夏到冬的变化也不与从冬到夏的变化对称。 3.东風帶向西風帶的角動量輸送,主要發生於西風环流破坏的時候;主要發生於“引伸槽”和“引伸脊”的經度帶;同時也主要發生於大气的...

It is founded by several authors that: the total angular momentum of the atmosphere decreases from winter to summer, compensating the increase of the angular momentum of the solid earth in the same period (principle of conservation of total angular momentum of an isolated system). However the average (over the globe)westerly circulation in the lower atmosphere (from 800 mb to surface) is stronger in summer than in winter. It is the authors, opinion that: it may be this increase from winter to summer of...

It is founded by several authors that: the total angular momentum of the atmosphere decreases from winter to summer, compensating the increase of the angular momentum of the solid earth in the same period (principle of conservation of total angular momentum of an isolated system). However the average (over the globe)westerly circulation in the lower atmosphere (from 800 mb to surface) is stronger in summer than in winter. It is the authors, opinion that: it may be this increase from winter to summer of the westerly circulation near the earth's surface, that speeds up the angular velocity of the earth's rotation from winter to summer. It may also be this increase that causes a higher rate of destruction of atmospheric angular momentum in summer, thus diminishing the total amount of the angular momentum from winter to summer.

把大气和地球看成一个孤立的系统,则此系统之总角动量不改变。从冬到夏地球本身的角动量增加,则同一时期大气的总角动量减少,但是低层大气(从地面到800毫巴)的平均西风环流夏季反而强於冬季,因此作者认为:从冬到夏近地面西风环流的这种加强,可能就是同一期间地转角速加快的原因;同时也可能是夏季大气角动量消耗率较高的原因。
