Mean winds and waves observed in the mesosphere and lower thermosphere with MF radars located at Davis (69¿ S, 78¿ E) and Poker Flat (65¿ N, 147¿ W) are compared. Measurements covering the period from 1999 to mid 2000 show differences in the strength of the horizontal wind fields. In the southern hemisphere the zonal and meridional winds reach their maximum values near the summer solstice, but are delayed by 2--3 weeks in the northern hemisphere. Gravity wave variances also show significant differences, as do the strength of vertical velocities. ¿ 2001 American Geophysical Union |
