Abstract: The accuracy and significance of a series of wind measurements at Johnston Island are discussed. The manner in which the chaff responds to changes in the wind is deduced from the observed rates of fall. The standard error ...

Abstract: A simplified model of the rainfall mechanism is used as a guide in developing a statistical formula, with readily measured variables as arguments, for forecasting precipitation amounts in winter at Washington, D. C. The ...

Abstract: The growth of small errors in numerical models of the atmospheric circulation destroys the detailed predictive capability of those models within a few days. Despite the failure of the models to produce accurate local ...

Abstract: A method for computing the probability of a cloud-free line-of-sight (CFLOS) between a given point in the atmosphere and a given point on the earth, was developed. The method is based on 3-hr synoptic weather reports of ...

Abstract: It is not possible to state at present just how much economic value either is derived or could be derived from present weather forecasts. It is, however, possible to analyze the weather factors that affect an industry. In ...

Abstract: Transosonde balloon data are analyzed to provide a measure of the dispersion on a large scale in the upper atmosphere. An expression for the autocorrelation function is inferred from synoptic experience and is applied to ...
