“…,.. For instance, ducted gravity waves apparently had an important part in the organization and maintenance of the simulated mid1atitude squall line of Schmidt and cotton (1989). Tripoli and cotton (1989b) stated new cells in their control run were generated by low-level convergence ahead of the gust front but when they reduced the winds in the control case by 50\, new convection sometimes developed ahead of the system in response to propagating gravity waves which appeared to be ducted by the leading anvil of the squall line.…”

“…A physical explanation of the layer inflow to convective updraft regions of MCSs is suggested by the work of Schmidt and Cotton [1990] and Pandya and Durran [1996]. These studies ran nonlinear high-resolution models and simulated the detailed behavior of a mesoscale system consisting of a squall line and trailing-stratiform region.…”

“…Gravity waves may propagate ahead of a system and thereby modify the inflow conditions (Fovell, 2002), and short gravity waves close to the system may contribute to triggering of new cells ahead (Fovell et al, 2006), especially where small but significant convective inhibition (CIN) may be modified by the waves (Morcrette et al, 2006;Marsham and Parker, 2006). Furthermore, a great deal of work has focussed on propagation mechanisms involving coupling between gravity waves and convection, as summarised by Cram et al (1992), including wave-CISK (convective initiation of the second kind) theories (Raymond, 1984) and the role of upper tropospheric gravity waves in exciting the rear inflow jet (Schmidt and Cotton, 1990). Pandya and Durran (1996) show that key features of two-dimensional squall lines can be accounted for directly from the gravity-wave response to the mean heating profile, largely that arising from the leading edge convection.…”
