“…To our knowledge, solid body rotations on a nonrotating sphere have been described firstly by Dey (1969) and on a rotating sphere by Umscheid and Sankar-Rao (1971). Taking into account that, except for the Coriolis term, the SSWE are invariant under a rotation of the spherical coordinates, an inclined solid body rotation with an inclination angle α = π 2 was given in Umscheid and Sankar-Rao (1971) and for arbitrary α ∈ [0, π] in Williamson and Browning (1973). Considering a more realistic zonal wind field, resembling a typical tropospheric jet, Browning et al (1989) deduced a steady state analytical solution with compact support.…”

“…A descrição da teoria geral de transformações conformes e de projeções clássicas pode ser encontrada em vários livros relativos as ciências aplicadas (por exemplo [3,6,12,14]), assim como nos livros de matemática [5,10]. Neste trabalho vamos nos referir principalmente ao livro de métodos matemáticos em cartografia de Pearson [11] e a uma revisão de geração de grades computacionais em modelos atmosféricos de Williamson [18].…”
