The paper describes the results of observations on the nature of the Effect of Sunset on Atmospherics. An automatic device specially constructed for the purpose was employed and with its aid, records of atmospherics on two wavelengths (37·5 metres and 375 metres) were taken for about two minutes at intervals of one hour throughout the day.
The study has brought to light certain interesting features characteristic of the period of investigation, which extended for a fortnight in the month of August 1940 and showed active monsoon conditions, particulaly between the the 11th and the 26th, in the Peninsula, the central parts of the country and North West India (
It is pointed out that (1) the effect of sunset on atmospherics is that of Trigger action, (2) the study of atmospherics can give advance information regarding the preparation of the atmosphere for the onset of a powerful thunderstorm and (3) prolonged atmospheric activity on the short waves appears to be connected with the formation of meteorological depressions.
