Abstract
An observation program was made to record cloud distribution over the Pacific Ocean, utilizing a 16mm time-lapse movie camera from an airplane along a routine flight course. As a test run for this observation flight, cloud distributions between Tokyo and Sado Island were observed. The result of the observation agrees very well with that predicted by synoptic considerations. It is therefore expected that the method planned will be useful in the observation of the cloud distribution over the Pacific Ocean where detailedweather maps are not available.
