We have constructed two new two-dimensional equilibrium magnetic field models for the Earth's magnetotail, in which flux tubes have nearly constant pV5/3 between the outer boundary of the Alfv¿n layers and 36 RE geocentric distance. These models, corresponding to different values of pV5/3, are constructed for magnetospheres with rectangular magnetopauses and nonflaring tails. These results thus confirm the speculation made in our earlier paper (Hau et al., 1989) that, within the limit of ideal MHD, there exists a family of steady state convection solutions, corresponding to various degrees of magnetotail inflation. Like our previous steady state solution, each of these models also exhibits a broad minimum in equatorial magnetic field strength Bze tailward of the inner edge region between 10 and 20 RE. However, these new steady state magnetic field models possess higher values of flux tube content pV5/3 and thus have more stretched tail configurations and smaller minimum values of Bze than those in the original model. For a model that has Bze/Blobe≈0.15 at 36 RE, which is close to observed averages, the ratio Bze/Blobe is about 0.029 at 13 RE. ¿1991 American Geophysical Union
