| Abstract | We document two kinds of traveling ionospheric disturbances, namely, CTIDs (Co-tsunami-TravelingIonospheric-disturbances) and ETIDs (Early-Arrivalthan-Tsunami-Traveling-Ionospheric-disturbances) related to the Tohoku-Oki tsunami of 11 March 2011. They are, respectively, referred to the disturbances that remain behind and ahead of the principal tsunami wave-front. We first note their presence in a numerical experiment performed using a simulation code coupling the tsunami, atmosphere and ionosphere. This code uses the tsunami wave-field as an input and simulates Acoustic-Gravity Waves (AGWs) in the atmosphere and TIDs, in the form of total electron content (TEC) disturbance, in the ionosphere. The simulated TEC reveals the excitation of CTIDs (at about 2 TECU) and ETIDs (at about 1 TECU), representing up to 5% disturbance over the ambient electron density, and they arise from the dissipation of the AGWs in the thermosphere. A novel outcome is that the strong ETIDs are excited about 20-60 minutes earlier (than the tsunami arrival time) at a location which is about 3o -10o ahead of the instantaneous location of the principal tsunami wave-front. Simulation results are compared with the far-field observations using GNSS satellites and in both, ETIDs are identified as the secondary TEC maximum, occurring 20-40 minutes before the tsunami arrival while the primary TEC maximum representing the CTIDs occurs 10-45 minutes after the tsunami arrival. The ETIDs reported in this study are a new kind of TIDs whose characteristics can be potentially used for the early warning of the tsunami. | |||
