    Abstract: The characteristics of whistlers generated from a gigantic jet (GJ) are modeled as well as to examine satellite observations. Modeling is based on disturbances in the electric field, as measured by NCKU ELF/VLF station, associated with a representative tree-like GJ event over typhoon Lionrock. The calculated frequency-time spectrogram shows two sequent whistlers, with the later one emitted mainly below a few kHz. Our results show that the waves are subject to greater attenuation as the frequency increases; however, a reversal occurs at lower frequencies of a few hundred Hz due to ion effects. The electric fields observed by DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) satellite mission are then investigated based on the locations of tree-like GJ events observed by ISUAL (Imager of Sprites and Upper Atmospheric Lightning). Paired whistlers, detected right after the tree-like GJ event occurred closest to the satellite location among all examined events, with power distribution features on the frequency-time spectrogram resembling modeled two sequent whistlers, are found.
