Abstract
An evaluation is made of techniques that have been or could be employed to determine the existence and nature of worldwide variations in atmospheric electric phenomena. In the course of a discussion of surface measurements, data from six sites on the surface of the earth are presented. The use of airborne vehicles in studies of global phenomena is discussed and results from soundings and transits are presented. It is concluded that, the use of instrumented aircraft is potentially the most promising technique to use, but that the expenditure of more care and effort than has been employed in the past is required if this potential is to be realized.

Abstract
TIROS photographs of cloud patterns in the vicinity of the jet stream are examined and compared with surface, upper air, and pilot-report data. It is found that with certain conditions of lighting and satellite attitude the northern edge of the cirrus cloud shield, which lies immediately south of the jet, can be easily identified by a shadow cast by the higher cloud deck on the lower underlying surface. This shadow identifies the cloud structure associated with the jet stream. Differences in texture and pattern also help to identify the northern limits of the high-level cirrus and thus aid in positioning the jet stream.
