Abstract:In this paper, the basic design idea of software and hardware of SWT-1 type sodar probing system,made in our country,is described.The user software of SWT sodar is also described more detailedly here. Continuous auto -acquisition and real-time processing of probing data and screen display of three-dimention wind profiles form of histogram could be realized. Moreover, the profiles of to'tal wind speed and wind direction, the values of temperature gradient, the wind speed and direction shear in the strata, and the relative statistical parameters, etc. could be printed out.

Abstract:The results of experiments on vapor field objective, analysis, supported by statistical interpolation, correction and straight-forward methods are compared. Statistical interpolation method is superior hi these experiments. The different characteristics of the three methods are investigated. A so-called mixed method which absorbs advantages of different methods is created. The new one improves the analysis quality.

Abstract:In this paper, annual and seasonal-precipitations in China are classfied by the fuzzy systems cluster method, A method used to find out the correlation coefficient within a certain class is given for objectively expressing of interclass correlation level. A principle for selecting of precipitation classification scheme is put forward. The results are satisfactory.

Abstract:The atmospheric environmental capacity is of great significance to the planning and reasonable distribution of industry as well as the emission control of pollutants. Taking the area of Maoming Oil Industrial Corporation for example, the evaluation method of atmospheric enviromental capacity is introduced. The results show that they are basically accordant with the actualities and the method proves to be reasonable.
