Confinement of the Sun's Interior Magnetic Field: Some Exact Boundary‐layer Solutions

摘要: High‐latitude laminar confinement of the interior field Bi is shown to be possible. Mean downwelling U as weak 2×10−6 cm s−1‐gyroscopically pumped by turbulent stresses in overlying convection zone and/or tachocline—can hold advective‐diffusive balance within a layer thickness scale δ∼1.5 Mm∼0.002R⊙. The sits at base high‐latitude tachocline, near top radiative envelope and just above ‘tachopause’ marking helium settling layer. A family exact, laminar, frictionless, axisymmetric confinement‐layer solutions obtained cylindrical polar coordinates, for uniform limit strong rotation Ωi stratification N. cannot penetrate must therefore feed into an equatorward flow immediately tachopause. retrograde Coriolis force on that balanced prograde Lorentz Buoyancy forces keep tachopause ap...
