mm!r’ . total complement of nine would have been ample to staff the weather center aboard the Mt. kKinley, if the facs~e charts could have been prepared in accordame with these suggestions. 9 8. Base Charts, Speci~ b-e ckfis were designed on which to enter the weather ? recauuissarme reports. These charts were large scale of approximately one inch to sixty miles. This permitted entering weather reconnaissance reports in full detail. The charts were printed on good qyaUty paper and used for making supplementary @Pes for such paranmters as misture content, cloud heights and stream lines. A special need was found for an overall base chart to cover a sufficient portion of the North and South Pacific to be adequate for forecastingat the Eniwetok area. The Navy HydrographlcOffice chart (HO 5556) which was used for surface synoptic analyses is too small a scale ad does not sufficiently cover the South Pacific. The Air Force WRC series 5-3 is of sufficientlylarge scale but does not adequately cover the area to the north or to the west. The ideal base chart for forecasting in the Eniwetok area should extend from the Philippine Islands to Hawsdi ad from the Aleutians to twenty degrees south latitude on a 1:10,000,000 scale. The use of a greatly reduced in seals base chart of the Hydrographic Office series (HO 5556) was employed to advantage h xs~ upper air data. 9. Weather Recomaisaance.
