The secondary layer may generally be subdivided into two main sublayers: the about 400 [micro]m thick outer sublayer with undular
laminae of the ribs (Fig.
Nocturnal MCS-induced cold pools often trigger undular
bores and solitary waves within the SBL.
On the other hand, for the same initial conditions as the ones discussed above but with dispersion and no diffusion, the initial steepening of the leading part of the initial profile caused by the nonlinear advective term is eventually somewhat balanced by dispersion and a dispersive shock wave or conservative undular
bore may form [17, 20, 21].
Nonlinear behaviour of pure gravity waves (Bo = 0) under resonant condition (Fr [equivalent] 1) has been intensively investigated experimentally [2,3] and numerically , and the fKdV equation has been found to give good results, including the generation of unsteady undular
bores upstream and downstream of the obstacle [5,6].

Jump became undular
at the discharge of 500000 and 1000000 cusec as upstream Froude number became 1.
For, aside from surmising that wavelike properties must be associated with microcosmic entities, de Broglie also specified the measurable aspect (wavelength) of this undular
These, rather than the lives of individual artists, are the basic units of art history, though too little is understood of what one might term the undular
mechanics of such surface perturbations to pretend that we know very much about what causes the swells, the crests, the breakers and the foam tides--or for that matter what accounts for the attenuation of movements when they at last subside.
As these trains frequently resemble combinations of internal solitary waves and undular
bores, we shall call such trains solibores in what follows.
SRSOR data showed rapid dissipation but also an undular
bore (Martin and Johnson 2008) over southern Wisconsin on the morning of 26 August 2013.
Its presence reflects a common feature of another class of weakly nonlinear disturbances--solutions of the KdV equation called undular
bore, a phenomenon known theoretically for more than 60 years (Benjamin and Lighthill, 1954; Peregrine, 1966).
In this article, a higher-order system of dispersive evolution equations and the associated energy integral are used to study the energy balance across an undular
