The energy conversion in the upper troposphere and the lower stratosphere and the energy transports across the tropopause are evaluated for the region 30°—60°N, 120°—70°W for a summer period in 1959. It is found that there still is the potential to kinetic energy conversion process in the lower layer of stratosphere, though with a net conversion of kinetic to potential energy. In the 40°—55°N latitudinal belt, all the kinetic energy, potential energy and sensible heat...

The energy conversion in the upper troposphere and the lower stratosphere and the energy transports across the tropopause are evaluated for the region 30°—60°N, 120°—70°W for a summer period in 1959. It is found that there still is the potential to kinetic energy conversion process in the lower layer of stratosphere, though with a net conversion of kinetic to potential energy. In the 40°—55°N latitudinal belt, all the kinetic energy, potential energy and sensible heat are transported from the stratosphere to the troposphere, and in both the belts north of 55°N and south of 40°N the transports are reverse in direction. It suggests that the stratosphere and mesosphere may play an important role in the energy equillibrium of the troposphere.

本文挑选了一个适当地区适当时段,对於平流圈下层和对流圈上层的动能位能转换及穿越对流圈顶的动能、位能、可感热进行实际计算。发现在平流圈下层仍存在使位能转换为动能的过程,但有动能向位能的淨转换。在对流圈上层有位能向动能的淨转换。在40°—55°N纬带内,巨大的动能、位能和可感热的输送从平流圈进入对流圈,其南及其北的纬带内所有能量则从对流圈输入平流圈。计算结果指出:关於对流圈中能量平衡问题,是不能把对流圈孤立处理的,而必须要考虑到和平流圈及中圈大气的联系问题。

The stability problem of rotating parallel flows was discussed by use of the barotropic vorticity equation. A stability .criterion of barotropic stability was obtained. It is an explicit expression which relates the perturbation growth rate to the function of the energy conversion between basic motion and perturbation. The results indicate that the growth rate of perturbation is proportional to that of the energy conversion. In addition, the case of a basic flow with horizontallinear shear was treated...

The stability problem of rotating parallel flows was discussed by use of the barotropic vorticity equation. A stability .criterion of barotropic stability was obtained. It is an explicit expression which relates the perturbation growth rate to the function of the energy conversion between basic motion and perturbation. The results indicate that the growth rate of perturbation is proportional to that of the energy conversion. In addition, the case of a basic flow with horizontallinear shear was treated for β≠0. Some results obtained are similar to that given by Haltiner (1971) for 0 = 0. The perturbations are damped waves. The wave speed, however, has a westward component which depends upon the strength of the shear of basic flows.

本文利用正压涡度方程讨论了旋转平行流的稳定性问题。导出了一个显式正压稳定性判据。它把扰动的增长率(kc_i)与能量转换函数直接联系起来了。结果表明,扰动的增长率正比于基本流与扰动间的动能转换率。此外,还讨论了基本流具有线性切变的情形,所得结果与Haltiner所给出的β=0时的结果大致类似。

Fluid field dissolution shows that maintenance and evolution of the mean circulation can be studied by analyzing kinetic energy equlibrium. 500-mb pentad height data from 1972 through 1980 are used for calculating mean zonal kinetic energy, eddy kinetic energy and the rate of their conversion. The results indicate that the interrelations between the three parameters for kinetic energy of the mean pentad circulation as well as their seasonal and other periodical variations are analogous to, but smaller than,...

Fluid field dissolution shows that maintenance and evolution of the mean circulation can be studied by analyzing kinetic energy equlibrium. 500-mb pentad height data from 1972 through 1980 are used for calculating mean zonal kinetic energy, eddy kinetic energy and the rate of their conversion. The results indicate that the interrelations between the three parameters for kinetic energy of the mean pentad circulation as well as their seasonal and other periodical variations are analogous to, but smaller than, those of the instantaneous circulation. Analyzing the sequence of the parameters by the power and cross spectra yields main periodic changes of quasi-two-week oscillation. It is then found from the wave spectrum and mechanism of kinetic energy parameters that such oscillation is behavior of extra-long-wave activity in energy cycle. The primary process consists in the peak value of kinetic energy conversion occurring 3—4 days after the eddy energy has attained a peak one and in another 3—4 days the zonal average kinetic energy exhibits the same one.

本文首先用流场分解方法说明平均环流的维持与演变可以通过对其动能的分析来研究。然后利用1972—80年逐候北半球500毫巴高度资料计算出纬圈平均运动动能、涡动动能及两者间的转换率。结果表明,候平均环流动能三参数的相互关系及其季节变化与瞬时环流的情况相类似,但数量上小于瞬时环流。对三参数序列应用功率谱和交叉谱分析得出,其主要周期变化为准两周振荡。再从动能参数的波谱分析和机理分析出发,指出准两周振荡就是超长波活动过程在能量循环上的反映,其大致过程是涡动动能达峰值后3—4天动能转换率达峰值,以后再过3—4天纬圈平均运动动能达峰值。
