For 9.6μ band of ozone, theory and experimental results show that the pressure-correction (p/p0)K for optical length ?of absorbing gas is a function of p and u.

Based on the data of radiation and evaporation from Beijing Solar Radiation Station and Quanting Evaporation Station, the Penman's formula is corrected aswhere HO is the radiation balance expressed in evaporation units, Ea is the "drying power" determined from windspeed and the vapour-pressure deficit. Evaporation from open water may be expressed by equationwhere F is heat flux downward from water surface. During the increasing temperature season its sign is plus, and in decreasing temperature season minus. Since we lack the data of water temperature gradiant, F cannot be directly calculated. In this paper it is suggested that the regressive equations of E depending on E0 may be respectively established during increasing or decreasing temperature season. Thus, the monthly values of evaporation in warm season in Beijing may be estimated by following formulas

In this papar, a direct method for calculating divergence, vorticity and vertical velocity on computer, without objective analysis, is proposed. Similar technique is applicable to calculation of physical quantities, such as gradient, advection and flux.However, in practical application, there still remain some problems to be solved, such as the inconsistency between the number of the vertical boundary conditions usually specified in an atmospheric model and the order of the equation of continuity, the problem how to calculate the vertical velocity in the case of uneven vertical resolution and the case of mountainous regions.To tackle these problems, some preliminary methods have been suggested and the equivalency of two different formulations of vertical velocity has been discussed. The formulations are as follows. 1. If the vertical distribution of div V is given, solve the equationunder the condition: at p = p0, ω = 0; 2. If the vertical distribution of is given, solve the equationunder the conditions: at p = p0, ω= 0 and at p = ps,ω = ωs. Here p0 is the pressure at the top of the model atmosphere assumed, and ps is that at the earth surface. It can be shown that only the conditionbeing satisfied can the two formulations be said to be equivalent to each other.Finally, calculations of some physical quantities for a case of large-scale heavy precipitation in South China are given. The results seem reasonable and in agreement with most forecasters' experiences.

提出了一个直接用观测资料,便于用电子计算机计算大范围散度、涡度和垂直速度的方案。还提出了计算某些物理量的梯度、平流和通量的方法。对于在垂直方向不均匀分层的计算,垂直边界条件个数和连续方程不协调的问题,以及在地形起伏的山地如何计算垂直速度等问题,也作了初步讨论。最后,用一次华南大范围降水的例子进行了计算,结果和预报员经验还比较一致。
