RADIOGONIOMETRIC INVESTIGATIONS OF THUNDERSTORMS AND CLOUDS OF GREAT ELECTRICAL ACTIVITY

Abstract

The first subject considered in this analysis is the precision obtainable with the NSR (Narrow Sector Recorder, after Lugeon-Nobile) and with the CRDF (Cathode Ray Direction Finder.) The errors forthcoming in the use of the two instruments are discussed. The requirements and the procedures to be applied for reducing these errors to a minimum are indicated. Particularly developed was the treatment of the possible errors in the coupling from two CRDF-stations: the equation of the curves joining all couplingpoints where the mean planimetric error assumes a constant value was derived. The circuit diagrams of the CRDF are given. An example is developed relative to the thunderstorm situation which occurred in southern France on July 1st, 1962, which demonstrates the performance of the CRDF-method in the synoptical analysis, with respect to the other procedures.
