[PEM06-02] Three-dimensional plasma bubble simulation driven by whole atmosphere-ionosphere coupled model
Keywords:plasma bubble, equatorial ionosphere, simulation, GAIA model, HIRB model
We have developed a new 3D high-resolution bubble (HIRB) model for EPB and presented nonlinear growth of EPB which shows very turbulent internal structures such as bifurcation and pinching. The eastward neutral wind in the evening produced reverse-C shape of EPB as frequently observed by various instruments. We are trying to integrate the high-resolution model for EPB with the whole atmosphere-ionosphere coupled model (GAIA) to study the growth of EPB under the realistic background conditions. The background electric field and neutral wind partially controlled by forcing from the lower atmosphere may cause the day-to-day variability of EPB occurrence.
