lee waves

waves on the sheltered side, away from the wind, of an obstruction; a meteorological wind phenomenon thought to play a part in abnormal down-wind transmission of foot-and-mouth disease.

What follows in the sections below concerns first the main science efforts to consolidate our understanding of turbulence from 1) mixing elevated over rough topography related to internal wave generation by tides, 2) low-frequency flows that generate internal lee waves, and 3) near-inertial internal wave generation by winds.
Local mixing occurs through tidally generated, transient, arrested lee waves (Legg and Klymak 2008; Klymak et al.
For turbulence at tall, steep slopes, a new parameterization of the near-field mixing due to transient arrested lee waves (Klymak et al.
2014) gives rise to vertically propagating internal lee waves of frequency Uk, where k is the topographic horizontal wavenumber and U is the mean flow speed.
Available global estimates for the energy conversion rate from geostrophic flows into internal lee waves range from 0.
2014) using the estimated global map of energy conversion into lee waves of Nikurashin and Ferrari (2011; Fig.
The inline implementation allows for feedbacks between wave drag and the low-frequency flows that produce the lee waves.
The tethersonde site on the southwest sidewall was moved slightly up the slope after the first IOP because the initial site seemed to be too close to the downstream edge of the lee wave and warm-air intrusions.
The shallow inversion at the bottom of the warm-air intrusions marks the depth to which the lee wave penetrated into the crater.
This can be caused either by horizontal movements of the tethered balloon because of strong winds and turbulence or by a smaller lee wave so that the ascending branch of the wave was located over the tethersonde site.
The lidar scanning strategies designed to visualize the lee wave in the crater (Cherukuru et al.
