Ji. Yano et al., Wavelet analysis of simulated tropical convective cloud systems. Part II: Decomposition of convective-scale and mesoscale structure, J ATMOS SCI, 58(8), 2001, pp. 868-876
Numerically simulated three-dimensional tropical convective systems were an
alyzed using a wavelet approach in which the vertical shear of the ambient
wind is used as a decomposition criterion. The method objectively decompose
s the simulated systems into their two primary components, namely organized
deep convection and a mesoscale stratiform region. This reproduces the sta
ndard model of highly organized mesoscale convective systems as well as giv
ing an objective characterization of less organized regimes. It demonstrate
s the vertical component of wind shear as a statistically useful criterion
in addition to its better known role as a quasi-deterministic mechanism con
trolling the organization of convection and its scale selection.
