Abstract: Lightning in the form of electromagnetic radiation, in very low frequency (VLF) and low frequency (LF) bands, is received on 1 April and 7 April 2015 from 10 kHz to 300 kHz over Kalyani during pre-monsoon thunderstorms. Their characteristics, viz. the spectral pattern and other relevant properties, are examined with the help of radio frequency (RF) spectra. Another severe thunderstorm experienced, over a wide area covering different parts of South Bengal including Kalyani, on 11 April 2013 has also been recorded in the form of integrated field intensity of atmospherics at 27 kHz receiver. After analysing, some interesting results are reported related to radio signal reception originating from lightning as electromagnetic radiation.
