Weather influences fmm the 5outhern Hemisphere unquestionably affect Eniwetok. However, inadequatelymeteorologicalreports fmm the southern hemisphere’were received to stuly th@se effects. Considerableeffort should tlmvfore be made to collect as such of the oouthern atmosphere weather data as poeaible in otier to analyze ad chart the atMspheric perturbationswhich result in storq tropical weather. In areaa whera there ia a predominance of alr transport operations, much enphasia iB placed on securing data in the strata where the transport planes operate. Because of this there haa been an emphasis on prumpt transmissionof upper alr data only to levels below 20,0(M feet. For an operation such as Sandstone, it is suggested that all rawinsonde data be transmitted in their entirety to the highest levels obtained. Ysis of Collected Data. 7. a.

In every ease the weatkr analyses were read with ease. This is in centrast to the nomal wfi garbleds an type radio teletype transmissionswhich generally completely useless ● The contents of the surface charts fnm Pearl and Guam contributed very little as a forecasting aid. The contents of the upper air charts contributednothirg. In the main this was due to the small area SECTION XII ’72
