The most important coherent structures in thermal turbulence are plumes.  Despite being the primary heat carriers, the potential of manipulating thermal plumes to transport more heat has been overlooked so far.  The result is the formation of highly coherent system-sized plumes and the emergence of a new regime of convective thermal turbulence characterized by universal temperature profiles and significantly enhanced heat transfer.  It is also found that the universality of the temperature profiles and heat transport originate from the geometrical properties of the coherent structures, i.e., the thermal plumes.
