Convectively coupled equatorial waves

摘要: [1] Convectively coupled equatorial waves (CCEWs) control a substantial fraction of tropical rainfall variability. Their horizontal structures and dispersion characteristics correspond to Matsuno's (1966) solutions the shallow water equations on an beta plane, namely, Kelvin, Rossby, mixed Rossby-gravity, inertio-gravity waves. Because moist processes, tilted vertical CCEWs are complex, their scales do not that expected from linear theory dry The dynamical cloud morphology display large degree self-similarity over surprisingly wide range scales, with convection at leading edge, followed by deep then stratiform precipitation, mirroring individual mesoscale convective complexes. have broad impacts within tropics, simulation in general circulation models is still problematic, although progress has been made using simpler models. A complete understanding remains challenge meteorology.
