Abstract
The aspects of the cloud formation over the Japan Sea during the three day period from Feb.10 to Feb.12,1962 was analysed by using T. V. data and channel 2 radiation data of TIROS IV in the author's previous report.
In this report, the distrribution of the albedo over the Japan Sea and her neighbourhood during the period mentioned above is obtained by using channel 3 radiation data. The bright areas in channel 3, which indicate solid overcast, are very well correlated to low equivalent black body temperatures in channel 2. The estimations of cloud cover and cloud height over the Japan Sea are tried by coordinating the albedo and equivalent black body temperature. It is shown that, under the winter monsoon situation, cloud cover increases rapidly 2-300 km off the shore of the Japan Islands and that the cloud exists mainly under the inversion layer.
