The variations of the SAA variables, as demonstrated in this study, were due to external magnetic field changes. It must be noted that the plot of both variations (red and blue contour lines) in all of the three panels was drawn for illustrative purposes, not according to realistic situations. A meteoroid traveling supersonically through Earths atmosphere produces a shock wave generated by the extremely rapid compression of air in front of the meteoroid. Ferraro current, particularly when the ram pressure of the solar wind stream is exceptionally high (Gonzalez et al., 1989. The movement of the SAA center location and the variation of the SAA area are shown in Panels (b) and (c), respectively, in addition to a typical ground track of a LEO satellite. One of the effects of the continuous minor fluctuations in solar wind dynamic pressure is the oscillating motion of the magnetopause. In addition, the study placed a typical spacecraft at Low Earth Orbit (LEO) (colored in magenta) that traveled across the SAA anomaly a dangerous situation arose when the spacecraft body itself (rectangular shape colored with magenta) entered the high charging (= radiation) zone (colored in light red), whereas the safer region was outside of the SAA (colored in light blue). Regarding the space weather parameters, we considered the solar wind dynamic pressure, the interplanetary magnetic field components, \(B_\)), and the movement of the SAA center (= variations in longitude and latitude of the SAA center). For the physical parameters characterizing the SAA, the study considered the minimum magnetic field, the location (longitude and latitude) of the SAA center, and the area of the SAA. In essence, the structure of the MP regions under the unusually high solar wind ram pressure condition in this case does not seem to be qualitatively different from that observed under more typical. We studied the space weather effects on the South Atlantic Anomaly (SAA) magnetic response using Tsyganenko models. The MP/BL forms where the solar wind pressure bal-ances the geomagnetic pressure: Higher (lower) ram pressure forces the boundary inward (outward) until it equals the higher (lower) pressure of the dipolar geo-magnetic eld there.
