  Using direct numerical simulations, we study rotating Rayleigh-B\'enard
convection in a cylindrical cell for a broad range of Rayleigh, Ekman, and
Prandtl numbers from the onset of wall modes to the geostrophic regime, an
extremely important one in geophysical and astrophysical contexts. We connect
linear wall-mode states that occur prior to the onset of bulk convection with
the boundary zonal flow that coexists with turbulent bulk convection in the
geostrophic regime through the continuity of length and time scales and of
convective heat transport. We quantitatively collapse drift frequency, boundary
length, and heat transport data from numerous sources over many orders of
magnitude in Rayleigh and Ekman numbers. Elucidating the heat transport
contributions of wall modes and of the boundary zonal flow are critical for
characterizing the properties of the geostrophic regime of rotating convection
in finite, physical containers and is crucial for connecting the geostrophic
regime of laboratory convection with geophysical and astrophysical systems.
