“…The degree of disorderliness/irregularities in a dynamical system is defined by the entropy measures and thus describes its dynamical complexity. Notably, the underlying dynamics of the ionosphere as a dynamical system depends on the changes in external influences and its various internal irregularities leading to chaotic behavior and dynamical complexity (Ogunsua, 2018; Ogunsua et al., 2014; Oludehinwa et al., 2021; Papadimitriou et al., 2020; Rabiu et al., 2015; Unnikrishnan et al., 2006; Unnikrishnan & Ravindran, 2010). Based on the dynamical nature of the ionosphere, the occurrence of TIDs possesses some dynamical characteristics that need to be unveiled by determining the degree of dynamical complexity response in the dynamics of the ionosphere.…”
