Sažetak
The existence of seasonal variation in the tridiurnal variation in cosmic ray intensity is investigated in the present study. The data used in the analysis are the hourly counting rates recorded at Deep River over a period of about one solar cycle from 1961-1971. The tridiurnal wave is found to be persisting during each season. The amplitude of the wave varies from one season to another. A comparison between the amplitude of that wave for the different seasons with their mean value over the investigated period indicates that the presence of the tridiurnal wave may be arising from the geometrical inclination of Earth's axis to the ecliptic plane in the presence of semidiurnal anisotropy.
