Description/Abstract:
ON THE BASIS OF WINDS FROM FOUR SHOT DAYS OF CASTLE, THAT PART OF THE VARIABILITY OF THE COMPUTED FALL-OUT INTENSITY PATTERNS DUE TO THE VAR IABILITY OF THE WINDS IS INVESTIGATED. AN EXTREME CASE FROM SANDSTONE IS ALSO CONSIDERED. THE TENTATIVE OPERATIONAL CONCLUSIONS ARE DRAWN TH AT: (1) LOW LEVEL WINDS ARE QUITE LIKELY TO BE THE CRITICAL ONES FOR C ASES OF RAPID MARKED CHANGES IN FALL-OUT INTENSITIES; FURTHERMORE, SUC H POTENTIAL EXTREME CASES OUGHT TO BE RECOGNIZABLE. THIS IMPORTANCE OF THE LOWER WINDS MAY INFLUENCE CHOICE OF LEVEL FOR THE WEATHER RECONNA ISSANCE FLIGHTS. (2) SINGLE POINT WIND RUNS, WHILE PROBABLY ADEQUATE F OR MEDIUM RANGE FALL-OUT COMPUTATIONS, ARE INADEQUATE FOR RANGES OF TH E ORDER OF THE ENIWETOK-BIKINI DISTANCE. A MAP WITH RESPECT TO THE EXP ECTED HOT LINE IS PRESENTED, GIVING A BEST ESTIMATE OF THE THREE-HOUR VARIABILITY DUE TO WINDS IN FALL-OUT INTENSITY. SUCH A VARIABILITY REP RESENTS THE ERROR OF A THREE-HOUR PERSISTENCE FORECAST FROM THE LAST W IND RUN PRIOR T SHOT TIME - THIS SHOULD BE AN UPPER LIMIT TO THE ACTUA L FORECAST ERROR.
