The purpose of this paper is to find an accurate and reliable reduction method for the synchro-reduction domain including nine to fifteen virtual height data above the minimal appreciable frequency fmin. For this domain three higher ionization mo-dels with two variables are given, whereas six or eight lower ionization models with two variables are given for the ionization below fmin. At most twenty different reduc-tion results may be obtained for each h'-f curve by the least square method. It is possible to select an accurate result from the above calculations. 468 theoretical noc-turnal h'-f curves have been reduced. They possess different shapes, critical fre-quencies fc, semi-thicknesses H and fmin's, and these theoretical virtual heights have an accuracy of about 0.1 km. The maximal reduction errors of 462 h'-f curves are less than 5 km, whereas those of 6 curves are between 5-9 km.

A method is presented for initialization the primitive equation model including real wind and height data. Vertical mean mass divergence is set to zero as a kinematic constraint for eliminating the extra-gravity wave in the initial wind field. Errors in the real wind are altered by assuming that they effect only the divergence part of the flow. The three dimensonal consistent array of velocity components and the height are used as the initial value of the model. The numerical results appear to be better then the balance approximation. This procedure is more effective for the initializing the sub-synoptic circulation system.

Kinetic energy budget of sub-synoptic scale disturbance which produces heavy rainfall during Mai-yu season is computed by using conventional rawinsonde and height data. The main results of this study are as follows: 1) In the calculation of kinetic energy, divergence part of the wind cann' t be neglected; 2) Kinetic energy is exported from the disturbance toward the surrounding atmosphere; 3) The rate of kinetic enemy generation by rotational wind is negative, while that of divergence wind is positive in the upper and lower troposphere. The summation of two parts is still negative, then the subgrid scale kinetic energy exchange exerts a significant effect on the kinetic energy budget of the disturbance. In other words, moist convection developed in conditional unstable atmosphere is an important process in moist baroclinic atmosphere. Hence, probably this is a proof of the importance of role of water vapor in the motion of the atmosphere.These results are helpful to understand the mechanism of this disturbance and to improve the design of numerical model.

计算了梅雨期间产生暴雨的次天气尺度扰动的动能分布及其乎衡。结果表明:1)在动能计算中不能略去风的散度部分;2)暴雨期间,扰动向周围大气输送动能;3)旋转风的动能产生率为负值,散度风在对流层下层和上层产生动能,两者之和仍是消耗动能。这样,次网格尺度对流在动能平衡中起着重要的作用。即在条件性不稳定的大气中,发展起来的温对流是湿斜压大气中重要的一种过程。上述结果有助于了解扰动的机制和改进数值模式的设计。
