Professional Interests
George Bryan's main research interests are cloud dynamics and numerical model development. Recently, he has studied the intensity of squall lines, the surface-based cold pools (i.e., gravity currents) in mesoscale convective systems, the triggering and spacing of orographic rainbands, the resolution dependence of convective processes in numerical models, and the maximum intensity of tropical cyclones.
