Abstract
The mean difference in temperature ¯ΔT between a cirrus deck and an overshooting top in the shapes of an entire hemisphere and a spherical segment of a hemisphere is determined theoretically for different angles of view from a satellite sensor. The effects of changes in the area of the view and ¯ΔT on the equivalent blackbody temperature measured by a satellite are evaluated. Results show that changes in the mean temperature of the dome with the angle of view are as important as changes in the area of the field of view.

RADAR DETECTION OF A FRONTAL STORM 18 JUNE 1946
(Paper presented 28 December 1946 at the Annual Meeting, A. M. S., Cambridge, Massachusetts)
Abstract
The theory of radar storm detection is briefly stated and applied to detection of the frontal storm of 18 June 1946. The precipitation pattern associated with the front is found to be a series of overlapping line squalls each about 100 miles in length. The mean rain intensity along the front is computed with the aid of radar theory.

Abstract
The theoretical growth of hail and the behavior of the first radar echo in a cumulus cloud are analyzed. Good agreement is found between the theory and the observations of Workman and Reynolds.

Abstract
A radar study of the streamers of 25 February 1954 at Cambridge, Mass., indicates that horizontal bands of rain are produced by the action of wind shear on the precipitation particles. It is suggested that a “generating layer,” responsible for the streamer formation, consists of a cumuliform cloud configuration within which ice crystals grow rapidly both by sublimation and by riming.
