The Weather Central was able to cope effectively with the huge mass of @ raw data coming in at all times, translate the data into usable form, and mect all requirements of the command without dolay or confusion, New mothods of tropical anal-sis were omployed with Some success, h. Onc disapoointing feature of the operation was the failure to establish a reliable and satisfactory radio facsimile link between the WNIYETCK Central and. Andrews Air Force Pase, Mar-land, Although the necessary roeguirament had becn os- tablished through proper chamncls, and agrecment reached that the facsimile Link for Lransinission of special charts would be fully operational by 1 dJaruary 1951, the service was never satisfactory and made little contribution to the operation until about 20 April 1951. i. The charts actually roccived, how.ver, were vory useful. Similarly, obligations acsumed by the Navy ab TAP, TRUK, and PONAPE Were not completely fulfilled. The Chici of kaval Operations had directed that spec- lal upper wind equinment be installed at these locations, personnel augmented, and special reports be made avalluble for CGperation CRELNHOUSE, Various difficulties wore experienced with equipment due to non-delivery of critical items and apparently poor condition of that which did arrive. While thoir surface reports wore of eonsi- derable value, the lack of reliable uppor wind data to high Jevols was a handicap, j. The primary m.ssior of the weathor program vas to furnish weabher inies formation and forccasts necessary for the accomplishment cf the tests and the completion of related experimented prozrams. 2. This riiesion was successfully accomplished, MAJOR EVENTS The following is a chronological, generally non-technical, sumiary of major events concerning the weabhuer program in CRUBNHOUSE. ALL times and dates are JIKE (180° cast longitude), except those specifically indicated as ZEbRA, a, TYPHOON GRORGTA (1) First indications of a suspicious development in the equatorial Pacific were noted on 16 and 17 March 1951. This unusual develop- mont consisted of a well developed deep current with extremely strong south winds, to an altitude of 55,000 feet over KUSATE,*~ Pahene be wo ate . wa Ea oe" k u > : A £ + aehab deo Al,§!
