  energy flux
The radiant energy flux from the shock layer is partially absorbed by a vapor layer and falls on the surface of the body, causing intense vaporization.

  flux of energy
As a result, an additional azimuthal flux of energy with an angular momentum opposite to that of the fundamental flux is induced.
      
By using the maximum entropy ansatz for the closure one obtains, in the limit of small anisotropy, explicit constitutive relations for the stress tensor and the flux of energy flux tensor.
      
The theme of this paper is the computation and estimation of the flux and absolute flux of energy across hypersurfaces for evolution equations.
      
The main surprise is that for smooth rapidly decreasing solutions of the wave equation or Schr?dinger equation in dimensions greater than one, the absolute flux of energy across a hyperplane can be arbitrarily large compared to the total energy.
      
Our results thus support the idea of a flux of energy not always oriented towards an increasing particle size range.

The study is based on the close relation between energy fields and the motion of typhoons in attempt to develop a new means for forecasting the movement of the depressions by examining the variations in energy fields.By investigating the total moist potential fields of Typhoons numbered as 7504,7708,7806,7909 and 7910, the authors have found the correspondence between these fields at isobaric surfaces and the closed energy field system (▽~2 Eσ<0 above 700mb and ▽~2 Eσ<0 at lower levels)as well as the same trends in their movements. Moreover, analysis shows that there exists an intense energy transport belt along the typhoon's track as the tropical cyclone moves and travels basically in the direction of gradients of horizontal flux at 500mb level, Charts of VEσ and ▽·(Eσ) can be used as an additional means for judging typhoon movements in troublesome situations.

基于能量场的变化与台风移动有密切关系的事实,本文试图从讨论能量场的变化入手,探讨通过预报能量场系统的移动以预报台风移动的方法。通过对7504、7708、7806、7909、7910号台风总湿位能场的分析,发现台风在各层等压面上均对应着闭合的能量场系统(700毫巴以上▽~2E_σ<0,低层▽~2E_σ>0),且两者的移动路径一致。此外,能量通量场和能量通量散度场的分析结果表明,在台风的进路方向有明显的强能量输送带,台风基本上沿着500毫巴能量水平通量散度梯度的方向移动。VE_σ图和▽·(E_σ)图可以作为定性判断台风疑难路径的一种辅助工具。

Through using the aerological data of August-September, 1982, theenergy exchange and its oscillation between the eastern and westernmonsoon regions in Asia are calculated and analyzed. It is found that various kinds of energy are transported from theplateau monsoon region to the North China monsoon region whereassensible heat, potential and kinetic energy are transported from SouthChina Sea monsoon region to Indian monsoon region. These transportsprimarily take place in the upper troposphere. It is worthy to notethat latent energy, though small in amount, is transported mainly bythe low--level southwesterlies from Indian monsoon region to SouthChina Sea, and it is an important factor for the monsoon rainfall. Thepredominant oscillation periods of the energy flux in the two southernmonsoon regions are longer than the two northern monsoon regions,being about two weeks and four weeks for the former and about twoweeks and three weeks for the latter. The oscillation period at upperlevel is longer than at lower level, with the weekly oscillationmainly occurring at the lower levels. Difference in initial phasemay exist between the upper and lower levels even though theperiods are identical. This phase lag is probably an important causeof periodic occurrence of strong convective weather.

本文应用1982年8—9月的气象资料,分析计算了亚洲东部的南海季风区和华北季风区与其西部的印度季风区和高原季风区之间的能量交换及其周期振荡。高原季风区向华北季风区输送各种能量,南海季风区向印度季风区输送感热能、位能和动能,主要是从高层输送的。值得注意的是印度季风区向南海季风区净输送潜热能,主要是由低层西南季风输送的,虽然其数量相对地较小,但对于季风降水却是重要因素。南部季风区能量通量的主要振荡周期较北部季风区长,前者为准双周和准四周,后者为准双周和准三周。高层的振荡周期长于低层,准单周振荡主要出现在低层。同一主要振荡周期,高、低层的初始位相有差异,这种位相差可能是造成强对流天气周期性出现的重要原因。

The energy flux derived from the barotropic vorticity equation differs from that obtained directly from the momentum equation. We re-study this problem raised in early 60's. The results show that if the momentum equation is rewritten in such a form that it contains the same conditions as that for barotropic vorticity equation, then the same energy flux form can be obtained for the waves with the constant amplitude. With this new momentum equation, the potential energy of Rossby wave is derived and the Lagrangian...

The energy flux derived from the barotropic vorticity equation differs from that obtained directly from the momentum equation. We re-study this problem raised in early 60's. The results show that if the momentum equation is rewritten in such a form that it contains the same conditions as that for barotropic vorticity equation, then the same energy flux form can be obtained for the waves with the constant amplitude. With this new momentum equation, the potential energy of Rossby wave is derived and the Lagrangian of the non-linear barotropic vorticity equation can be found approximately with this potential energy. This privides the physical basis for studying the dynamics of non-linear Rossby wave with the approach of variation.

利用正压涡度方程计算波动能量通量时,它的形式将不同于直接利用运动方程所求得的通量,这是一个于六十年代初所提出的问题。在本文中,对此问题进行再次分析与研究。结果表明,如果将运动方程进行改写,使其包含了与涡度方程相等的条件,对于波动而言,就整个波动范围求平均且假定波动振幅为常数,则可得到相同的表示式。于文中,还利用此改写的运动方程,导得了波动位能的表示式,这为进一步研究非线性Rossby波提供了一个物理基础。
