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。

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。

In this paper, a barotropic vorticity equation model is used to investigate the relationship between midlatitude response of tropic forcing from different longitudinal positions and Northern winter stationary waves of basic flow. The results indicate that for the tropic forcing over most area of Indian Ocean and Pacific the midlatitude response patterns are determined mainly by the structure of the basic flow and are supported by the kinetic energy conversion of basic flow to perturbation. These results could interpret the finding that the structure of the GCM's midlatitude response is insensitive to the longitudinal position of the SST anomaly forcing during El Nino episode. Moreover, the roles of zonally oriented low frequency dipole convective anomaly forcing appeared in observation and GCM simulaton on GCM midlatitude response are also discussed.

本文利用正压涡度方程模式研究了热带不同经度位置异常强迫激发的中纬响应类型与北半球冬季基本气流定常波结构的关系。发现对热带印度洋和太平洋的大部分地区,中纬的响应类型主要由基态定常波的结构决定,并且基态定常波通过向扰动转换动能维持了中纬的响应。通过这些结果解释了GCM研究中发现的中综异常响应类型对El Nino成熟期海表面温度异常位置变化的不敏感性。此外还讨论了观测和GCM中出现的热带印度洋——太平洋地区低频尺度上的纬向偶极强迫源对GCM响应结果的作用。
