Abstract
Data obtained at O'Neill, Nebraska, during the summer of 1953, particularly data dealing with temperature fluctuations, have been examined to obtain information on eddy sizes. It was found that under conditions of lapse and slight inversion, the eddy sizes affecting any one level varied only slightly. Thus, on the assumption that the vertical temperature distribution was logarithmic, it was calculated that two thirds of the eddies affecting the 2-m level under these conditions lay between 0.5 m and 7.5 m in vertical extent. With increasing stability, the sizes decreased rapidly. Under all conditions of stability, the eddy size increased with height. Under inversion conditions, the increase was more rapid and, under lapse, less rapid than the logarithm of the height.Keywords
