Tsallis’ Analysis of the Horizontal Component of the Earth’s Magnetic Field over India during 2002

A widely used measure of entropy to quantify uncertainity in an open system is the Boltzmann-Gibbs (B-G) entropy. It, however, cannot describe non-equilibrium systems with large variability and multi-fractality. generalisation B - G Tsallis’ The values horizontal components Earth’s magnetic field, observed at various stations India 2002 were used. During years 2000 – 2002, solar cycle 23 reached its maximum. Data from Ettaiyapuram (ETT, latitude = 90 10’ N, longitude 780 01’ E, geomagnetic 0.130 N), Visakhapatnam (VIS, 170 41’ 830 19’ 8.170 Hyderabad (HYD, 25’ 33’ Alibag (ABG, 180 37’ 720 52’ 10.020 N) Tirunelveli (TVI, 80 42’ 770 48’ 0.320 S) Using these as inputs, we demonstrate that can be detect minor differences field between different pairs stations. method a very simple elegant one variations similar signals.
