Theoretical modeling of the occurrence of equatorial and low-latitude ionospheric irregularity and scintillation

2013 
In this paper,the three-dimensional linear growth rate of Rayleigh-Taylor(R-T) instability depending on the local time is investigated based on the analysis of the generalized three dimensional R-T instability.The maximum of the growth rate in a day is taken as the signature of that day.The characteristics of three-dimensional linear growth rate varying with the seasons,solar activities,geographic longitudes and day-to-day variations are studied and modelled.The variations of growth rate significantly rely on the local times,seasons,solar activities,longitudes and also day-to-day.Comparing the characteristics of the growth rate with the characteristics of the irregularities and scintillations in equatorial and low-latitude ionosphere,it is found that three-dimensional linear growth rates of the R-T instability display similar characteristics with that of the irregularities and scintillations,the growth rate can be used in modeling the theoretical characteristic of the occurrence of the ionospheric irregularity and scintillation.
