| Zusammenfassung |
A quantitative model of the magnetospheric
magnetic field is developed using poloidal vector fields. This formalism is
applied to the ring current region, the distant field and the return currents.
The tail model is similar to the unwarped model of Tsyganenko. Several sets of
coefficients are obtained for different Kp through a fit of the NSSDC data base.
Experimental ΔB contours and theoretical distributed currents
contours are correctly described and are Kp-dependent. Field line topology
problems and poor ring current description observed in models of similar
complexity are avoided. Computer time has been kept reasonable and makes this
model particularly adapted to intensive-type calculations.
Key words. Magnetospheric physics (magnetospheric ·
configuration and dynamics).
