FALLOUT PREDICTOR. Quarterly Report No. 3 for January 1 through March 31, 1959
BS>A functional fiow chart of a program for calculating fallout is presented. Four different means of predicting the stabilized height of the cloud center are given. A simplified concept of cloud shape is described and formulas for determining the thickness and diameter of the mushroom are presented. Equations are derived for specifying a radioactive model of the bomb cloud. Methods are presented for determining the normalized dose rate and the accumulated dosage due to fallout. A brief review of wind input sources is followed by a discussion of vertical air motion forecasting methods and associated shower activity. The influence of topography on wind fields is discussed. Methods of silent area and single station forecasting are described. A method of dividing the bomb cloud into small pieces and operating on these pieces to determine their final ground positions is presented. The application of radar support information to rainout is discussed. A method is suggested for including the wind deviation in the total fallout prediction. The structure of a typical digital computation svstem is described and a preliminary estimate is made of the storage requirements of the predictor. (auth)
