Fig. 4From: On the modelling of M2 tidal magnetic signatures: effects of physical approximations and numerical resolutionMagnetic signatures of \(\hbox {M}_{2}\) tides. The real (left column) and the imaginary (right column) parts of the three magnetic field components at the Earth’s surface calculated using the elmgFD code with 2-D surface conductance and forcing at the highest lateral resolution, \(j_{\mathrm{max}}=480\). Note the use of different colour scales for vertical and horizontal componentsBack to article page
