1 Fig. 5 Morphology of in situ peak Poynting flux during storm periods.
Morphology of in situ peak Poynting flux during storm periods. The global distribution of peak wave Poynting flux during storms (Dst < −40 nT) flowing toward Earth as measured at high altitude (4 to 7 RE geocentric) in the Northern Hemisphere obtained from 6 years of Polar measurements and scaled along converging magnetic field lines to ionospheric altitudes (100 km). Each bin covers 2° magnetic latitude times 0.75 hour local time. Circles represent magnetic latitudes (60°, 70°, and 80°); radial lines indicate local times (e.g., 6, 12, 18, and 24). The black circle in the center was not analyzed. For a few bins (black), Polar did not encounter storm conditions; hence, no Poynting flux values are shown. The two dashed oval-shaped curves delineate the statistical auroral oval for geomagnetically active periods (15). Andreas Keiling et al.
