“…The remaining portion (approximately 32%-16%) can be explained by the other effects which are not including to model here (such as, lightning, earthquakes, tides) of sub-atmospheric origin. The results obtained are supported that the ion-generation processes that occur in the lower ionosphere are closely related to the chemistry of neutral components and to meteorological processes [Krivolutsky 2009].…”

“…It is noted that, none of these statistical studies provides any physical mechanism to determine the apparent relationships, but the QBO through the atmospheric waves [Pancheva et al 1991] may have a greater effect on the N n D in the D-region, which is considered as weakly ionized plasma. Apart from causing a statistical decrease in the N n D due to the QBO, it is also may give rise to changes in the ion chemistry of this region [Krivolutsky 2009]. This change would become physically and chemically by interacting with the carrying momentum by QBO of neutral components in D-region.…”

A multiple regression model, which defines relationship between two variables, is used to perform a statistical analysis of the relationship between the stratospheric QBO and the neutral density of the D region (NnD) at altitudes of 75 km and 90 km for Singapore station. While performing the analysis, the solar maxima and solar minima epochs of the sun for 21st, 22nd and 23rd solar cycles (SCs) are taken into account. Before applying the model for the statistical analysis of the relationship, the stationary of the variables is investigated by using the unit root test. The relationship between the variables is also investigated by using the co-integration test. The relationship between NnD measured at 75 km altitude and QBO obtained at altitude of 10 hPa is observed that it is positive for solar maximum epoch at 21st and 23rd SCs and for solar minimum epoch at 21st SC and is negative at the other epochs. The relationship between NnD measured at 90 km altitude and QBO is observed to be negative at both the solar maxima expect for solar maximum of 23rd SC and the solar minima epochs. The relationship between variables is positive for both phases (east and west) of QBO. Thus, QBO leads to a statistical change in the NnD. It may also give rise to changes on the ion chemistry of the D region.
