Linear and weakly nonlinear thermal convection in a moderately thin
\nspherical shell in the presence of a
\nspherically symmetric gravity subject to a spherically symmetric
\nboundary condition is systematically investigated
\nthrough fully three-dimensional numerical simulations. The convection
\nproblem is self-adjoint and the
\nlinear convective stability is characterized by l, the degree of a
\nspherical harmonics Y_l^m(theta,phi). While the radial
\nstructure of the linear convection is determined by the stability
\nanalysis, there exists a (2l+1)-fold degeneracy
\nin the horizonal structure of the spherical convection. When l=O(10),
\ni.e., in a moderately thin spherical shell,
\nthe removal or partial removal of the degeneracy represents a
\nmathematically difficult, physically not wellunderstood
\nproblem. By starting with carefully chosen initial conditions, we are
\nable to obtain a variety of
\nnonlinear convective flows at exactly the same parameters near the onset
\nof convection, including steady
\naxisymmetric convection, steady azimuthally periodic convection, steady
\nazimuthally nonperiodic convection,
\nequatorially asymmetric convection, and steady convection in the form of
\na single giant spiral roll covering the
\nwhole spherical shell which is stable and robust for a wide range of the
\nPrandtl number.<\/p>\n
