An electrical counting technique applied to a statistical study of atmospheric pressure fluctuations

Abstract

<p>A method has been presented for detecting and electrically tabulating fluctuations of dynamic and static pressures in the atmosphere. The method is used to present, in tabulated form, the data necessary for computations of the means, standard deviations, and correlation coefficient for two electrical signals representing the fluctuations of static and dynamic pressures. From the results, conclusions are drawn that the fluctuations in static and dynamic pressures are uncorrelated, that the standard deviation of both the static and dynamic pressure fluctuations increase in fairly regular fashion with increased wind speed, and that the ratio of the standard deviations of static and dynamic pressure fluctuations has a rough dependence on wind speed;The tabulating technique has a wide application for statistical examination of any variable that can be reduced to an electrical signal. The technique combines the advantages of relatively small lag error, compactness, and versatility with the ability to tabulate the data as they are accumulated, thus eliminating the time consuming process of manually transferring the data from conventional tape records.</p>
