 Abstract: The Rayleigh-Taylor instability growth rate (γRT) was estimated in order to investigate the impact of physical parameters that control the equatorial plasma bubbles (EPBs) development and compare the values with the EPBs occurrence data. γRT was estimated by using ionosonde data at Fortaleza (3.9°S, 38.45°W; dip angle: 9°S) and atmospheric models (IRI-2016, MSISE-00 and HWM-14). The EPBs occurrence was obtained by observing the rate of change of total electron content index (ROTI) using the ground-based global navigation satellite systems (GNSS) receivers in the northeast of Brazil. One year of data was used (2014). The comparison of γRT and the EPBs occurrence data indicates that the relationship between these two parameters could be characterized by a continuous probability distribution function. The results also indicate that background zonal and meridional winds, with the strength of the pre-reversal enhancement, are important factors to control EPB occurrence. The EPB occurrence probability is small when the γRT reaches negative values and becomes larger than 80% when the γRT is greater than 3 x 10-4 s-1. Some main features of the relation between the occurrence rate and from the point of view of the space weather concern will be presented.
