Abstract : TIROS IV nephanalyses for the months of March, April, and May 1962 were examined in conjunction with sixhourly surface charts to obtain examples where TIROS photographic series passed over surface frontal zones. The geographical area covered was limited to the Northern Hemisphere and extended from Japan, across the North Pacific Ocean, the Continental United States, and the North Atlantic Ocean. A total of 216 passes over frontal zone areas were selected for presentation, to illustrate the characteristics of cloud cover patterns in frontal zones for this series. To provide information on the synoptic scale atmospheric circulation systems in the vicinity of the frontal zone areas, sectional surface and upper air charts are used. The cloud cover photographs corresponding to the nephanalyses are displayed in a mosaic format, rather than selected single photographs, to bring out, in addition to the frontal cloud cover characteristics, the synoptic scale cloud cover features in the attendant atmospheric circulations. A unique color transparency overlay format is used to present the nephanalyses and synoptic scale surface and upper air charts. (Author)
