الوصف: An analysis of a mesoscale wave which occurred over the eastern United States on 6 March 1969 is presented. Its origin is attributed to the perturbation of a midtropospheric inversion by a squall line. After the wave formed, it propagated in the direction of the mid- and upper-level tropospheric flow and expanded as an arc with the center located near the region of convective activity. The wave travelled from western Tennessee and Kentucky over a distance of more than 1000 kilometers to Nova Scotia with a mean speed of 55 m s−1. The event was quite obvious on surface barographs throughout this region. Pressure traces showed an obvious V-shaped pressure drop of 3 to 6 mb over much of the wave path. The wave persisted for about 9 hours with little change in character. The synoptic situation is analysed and compared with similar atmospheric conditions in other studies. The generation mechanism of an internal gravity wave of depression is investigated by a simple model. It is found that wave of depre...
