abstract = "In this work, we present a simulation study of equatorial plasma
bubble (EPB) in the evening time ionosphere. The fluid simulation
is performed with a high grid resolution, enabling us to probe the
steepened updrafting density structures inside EPB. Inside the
density depletion that eventually evolves as EPB, both density and
updraft are functions of space from which the density as implicit
function of updraft velocity or the density distribution function
is constructed. In the present study, this distribution function
and the corresponding probability distribution function are found
to evolve from Maxwellian to non-Maxwellian as the initial small
depletion grows to EPB. This non-Maxwellian distribution is of a
gentle-bump type, in confirmation with the recently reported
distribution within EPB from space-borne measurements that offer
favorable condition for small scale kinetic instabilities.",
