Polarward

On the polarward side of the trough, the disturbance appears as the wave in the Easterlies described by Riehl [9].

In general, the polarward flow is strongest as a result of western intensification (Stommel, 1948; Munk and Carrier, 1950).

However, during low geomagnetic activity the distribution of latitudinally asymmetric events is close to Iijima and Potermra's Region 1 and 2 current picture: the equatorward events prevail in the morning and postmidnight sectors, and the polarward ones – in the evening and premidnight.

There is, therefere, a constant tendency with the air that these upper currents carry polarward to be crowded out, so to speak — to slough off and turn back.
