Abstract

The variability of wind with distance over New England during the period January–March, 1969, is compared to some general models and found to be larger than the models would predict. The difference is not unreasonable considering the location and the amount of cyclonic activity.

Abstract

The time-lag variability of winds at 3,6,9 and 12 km, observed at approximately 1-hr intervals over Bedford, Mass., during the first week of April 1960 is proportional to the square root of the time lag. The proportionality factor varies with mean wind speed, and perhaps also with altitude, thus differing from the average value found by previous investigators. Of the other sources of variability present in this unique series, deviations from precise 1-hr intervals were most important; less important, but still significant, were difference in the exact balloon positions when successive measurements were made, and in the exact heights to which they applied.
