Abstract : For making an objective analysis of aerologic field anomalies it is necessary to accumulate data on their statistical structure. Until recently few such data were available due to the difficulty of making the required computations manually. The availability of electronic computers has now made it possible to compute such characteristics. As the initial material we used data on the mean monthly values of geopotential and temperature at the 500-mb isobaric surface for the ten years from 1956 to 1965 as published by the United States Weather Bureau. The authors selected 48 aerologic stations located in the United States and Canada. Using these data for both elements for each month separately the authors computed the mean values and the mean square deviations for each station and also the spatial autocorrelation functions to distances of about 6,000 km.
