Research in this area focuses on the coupling of convection and large-scale
atmospheric waves, including diagnosing energy exchanges by radiation and
latent and sensible heat fluxes. We are interested in all ranges of wave and
convective activity: from mesoscale to planetary and from diurnal to interannual
and to climate scales. We use variety of diagnostic tools to understand
dynamical and physical processes. Early foci include understanding the
evolution and causes of the Madden-Julian Oscillation and its interaction with
monsoons, the relation of tropical jets and waves with convection and tropical
cyclone development, and the larger-scale coupling of atmospheric motions
with the ocean as part of the seasonal and ENSO variations.
