Description:

The tropical cyclone (TC) ‐induced concentric gravity waves (CGWs) are capable of propagating upward from convective sources in the troposphere to the upper atmosphere and creating concentric traveling ionospheric disturbances (CTIDs). To examine the CGWs propagation, we implementtropical cyclone ‐induced CGWs into the lower boundary of global ionosphere ‐thermosphere model with local ‐grid re ﬁnement (GITM ‐R) and simulate the in ﬂuence of CGWs on the ionosphere and thermosphere. GITM ‐R is a three ‐dimensional non ‐hydrostatic general circulation model for the upper atmosphere with the local ‐grid re ﬁnement module to enhance the resolution at the location of interest. In this study, CGWs induced by the typhoon Meranti in 2016 have been simulated. Information of the TC
