JOINT TASK FORCE SEVEN San Francisco, Califonria Los Almos ScientificLaboratory Location i Our weatherstudiesseem to be progressingquite satisfactorily.!Je have had a recent exampleof the relationof sun activityto our weather. It is not yet time to get real excitedover it, but in this case 6 days followingincreasedactivityof the sun we had an upset in the weatherpattern w%ch would have been more or less predictablehad we had the infornation in ttie. Rex gets his reportsfron Coloradoand only once a week by Sut we will trg to get then to send us the informationby radio. He is doing a splemiidjob and Palmer and his people at WheelerField liexhas made some interestingpresentationson falloutpatternsand when verticalcomponentsof wind are consideredit is reallyamazinghow the picture changes. In a specificermple which they mrked up, the falloutarea was increasedby a factorof about 20 in the westernsectorand about 4 in the easternsector. This was the B?AVO shot--theone so much discussedat the Some time ago we were asked whetherwe had any suggestionsfor different locationsfor shots. Ve have not done anythingspecific.
