Abstract
Abstract The records of VLF atmospherics over Calcutta and then over Kalyani West Bengal during the torrential rainfall caused by violent monsoon and postmonsoon depressions exhibit distinct longperiod fadings both at day and night Interesting results obtained from an analysis of roundtheclock atmospherics data and associated meteorological parameters are reported in this paper A possible correlation between the severe meteorological activity with the solar geophysical phenomena was studied The results are indicative of an interesting sequence of solarterrestrial events A tentative conclusion is reached suggesting an origin of the fading from atmospheric gravity waves generated in the centre of activity of the depressions concerned
