Statistical Analysis of Measurements
Statistical analysis has been increasingly used in recent years for treatment of the results of observations. The statistical nature of many atmospheric phenomena makes such analysis essential, and the development of diverse computational techniques (analog and digital) has provided the means for conducting the analysis. Hence, we must discuss, albeit briefly, the techniques of statistical analysis and, what is just as important, the accuracy of the results obtained. It should be noted that while the actual methods of statistical analysis are fairly well known, the question of the accuracy of the statistical characteristics obtained has received relatively little consideration in the meteorological literature. This, in turn, makes it difficult (and often simply impossible) to compare heterogeneous experimental data, and in addition, can lead to erroneous conclusions regarding the nature of the phenomenon. The results of statistical analysis are usually variances, structure and correlation functions, and spectral densities, which are simple and also the most important characteristics of meteorological fields.
