We present a three-dimensional simulation of collisional-interchange-instability in the equatorial-low-latitude F region of
ionosphere. The instability is responsible for the generation of large plasma density depletion or bubble. General 3D potential
and continuity equations are derived to simulate the phenomena. To understand the linear aspect of the instability, the general
3D linear growth rate is derived using 3D potential equation. The linear growth characteristics are compared with earlier
field-aligned-integrated growth analyses. The numerical simulation of bubble in the 3D spherical polar geometry is finally
presented. Distinct evolution characteristics of bubble in 3D and 2D simulation are further discussed. 相似文献
