  Multiple chaotic and turbulent regimes in Rayleigh-B\'{e}nard convection have
been studied and classified from the onset of deterministic chaos to the fully
developed turbulence using the distributed chaos approach supported by results
of laboratory experiments and numerical simulations. It is shown that the
regimes can replace each other depending on value of the Rayleigh number and
location in the convection cell (in the bulk of the flow or in the boundary
layers). The inertial-buoyancy and helicity based invariants play crucial role
in the formation of the regimes. Transition from the classical to ultimate
state has been also discussed in this context.
