C. Dear Dr. Graves? chonwd “SF “s phitbawdtlSnel!slag:LLBS SIES . a7HD ylnewtHuw’4 ace Thank you for providing me with the opportunity of reading the definitive text of "A Study of Certain Operational Weather Considerations Involving the Test and Delivery of High Yield Weapons". Since I did not understand, at the time the manuscript vas being prepared, that my name was to appear on the title page and since it would be an impertinence on my part to comment upon those mtters in the study which lie outside my field of knowledge I should like to state my position unequivocally. 1. I wrote the sections "Weather over the Marshall Islands" (Chspter 1) and “The Dynamics of Bomb Clouds" (Chapter 11). I have not as yet any reason for repudisting the statements contained in these chapters. However, certain misprints occur and these should be corrected in accordance with paragraph 3 of this letter. 2. Any conclusions in the report, other than those contained in the chapters referred to above, lie outside my field of competence. For example, sampling techniques and the delivery problem are matters about which I have no knowledge. ter. 3. On page 6 the diagram at the bottom of the page is out of regis- The 10 knot isopleths surrounding minima of speed should lie over theirazrergctire singularities in the vind field. On page LI, line & should read “ty? Tp» Ty represent the mean temperatures along the verticals AF, BE and cp,”. Sincerely yours, /s/ Clarence E. Palmer Clisrence ©.
