Abstract : The report describes the cloud data and some of the research results of Project 4.5, Task Group 3.1, Task Force III. A rational classification of tropical clouds characteristics of the Central Pacific Ocean is attempted; fifty-two color photographs of oceanic clouds are reproduced as a foundations for a tropical cloud atlas; and the topic of cumulus precipitation is treated at some length. Then follows a discussion of the techniques necessary to any attempt to forecast the movement and transformation of atomic clouds in low latitudes, the chief attention being paid to events following the first six hours after the explosions. A method of computing vertical motions in the free atmosphere is described and applied. The report concludes with a chapter of recommendations.
