Abstract:

Drift velocities measured at the high latitude Digisonde stations in Goose Bay, Argentia, and Millstone Hill are used to investigate the formation of mid-latitude troughs in the dusk sector. The observations show the existence of westward drift velocities of magnitudes comparable to the velocity of the earths rotation during trough formation. These drifts are part of the two cell convection pattern as implied by the stagnation theory of trough formation.
